10G SFP+ Transceiver Modules and Patch Cords Selection Guide

by www.fiber-mart.com
10G connection in telecommunication network is gradually moving from the backbone to layer 2 and layer 3. Both technology and market of 10G SFP+ transceiver modules are mature: the 10G transceiver modules have advanced from XENPAK which is the first generation of 10G transceiver to SFP+ which is now the most popular 10G optics. In addition, the price of 10G modules is getting lower. 10G modules are becoming affordable. Some genius guys even buy 10 SFP+ modules online to DIY private point to point 10G network. This article will offer basic information about 10G SFP+ transceiver modules and their connection instructions.
 
Basic of 10G SFP+ Transceiver Module
10G SFP+ transceiver has the same form factor of Gigabit SFP transceiver. Thus, many 10G modules can support 1/10G data rate to increase its flexibility during practical using. A SFP+ transceiver usually has two LC ports (as shown in the following picture). While 10G BiDi SFP+ transceiver, which transmitting and receiving signals from the same fiber optic cable, only has one LC port.
 
Except fiber optical transceivers, there are also various factory terminated copper-based or fiber optic based cables which are terminated with a SFP+ module on each end of the cable. There are mainly three types of these 10G cables: 10G SFP+ passive direct attached copper cable, 10G active direct attached copper cable and 10G SFP+ active optical cable. These 10G SFP+ cables eliminate the used of additional patch cable and can be directly plugged into the 10G SFP+ ports on switches. It is acceptable that these cables are an cost-effective and reliable solutions for 10G connections in short distance.
 
Optical Standards of 10G SFP+ Transceiver
According to IEEE standards, there are a variety 10GBASE SFP+ transceivers. For short distance transmission, 10GBASE-SR SFP+ and 10GBASE-LRM SFP+ can support transmission distance up to 300 meters and 220 meters over multimode fiber optic cables separately. 10GBASE-SR SFP+ modules is the most commonly used transceiver for short distance. It is suggested to work over wavelength of 850 nm.
 
There are a lot of 10G SFP+ transceivers that support long distance, like 10GBASE-LR SFP+, 10GBASE-ER SFP+, 10GBASE-ZR SFP+, CWDM SFP+, DWDM SFP+, BiDi SFP+, etc. These transceivers can support transmission distances ranging from 10 km to 120 km over single-mode fiber optic cables.
 
There is another special type of 10G transceivers which has been mentioned in this post, which is known as dual-rate SFP+. For example, dual-rate 1000BASE-LX and 10GBASE-LR SFP+ transceiver can be adjusted to support both 1G and 10G data rate up to 10 km over wavelength of 1310 nm.
 
Fiber Patch Cable Selection Guide for 10G SFP+ Transceivers
As 10G SFP+ DAC and AOC eliminate the using of additional patch cords. This part will introduce the selection guide for 10G SFP+ transceivers. During the selection of fiber optic patch cables for 10G SFP+ transceivers, the transmission distance is the first element to be considered. Single-mode patch cable is used for long distance transmission and multimode is designed for short distance transmission. Then the ports on the transceiver for receiving and transmitting should be considered. As mentioned, most 10G transceiver use duplex LC port, while BiDi SFP+ use simplex port (as shown in the above picture). Thus, simplex LC patch cords or duplex LC patch cords are used according to the port type on the transceiver. The following chart introduces detailed cabling information for 10G SFP+ transceivers.
 
This post just introduced the basic information of 10G optics and cabling information. For more specific information, please visit fiber-mart.COM, where you can find a variety of 10G SFP+ optics modules.

PLC Splitter Selection Guide

by www.fiber-mart.com
PLC splitter is a simple passive component which plays an important role in the applications of technologies like GPON, EPON and BPON. It allows a strand of fiber optic signal being equivalently splitted into several strands of optical signal, which can support a single network interface to be shared by many subscribers. When selecting it, split ratios should always be considered. However, with the network cabling environment becoming increasingly complex, various PLC splitters with different package form factors are being invented. Now the package form factor of it is also a key factor to be considered. This post will introduce the most commonly used PLC splitters in different package form factors for your reference during selection.
 
Bare Fiber PLC Splitter
Bare fiber PLC splitter is commonly used in FTTx projects. It leaves bare fiber on all its ends. Thus, they can be spliced by network engineer freely according to the applications. Meanwhile, it requires the least space during cabling. They can be installed in fiber optic splicing closure easily to provide FTTH signal distribution.
 
Blockless PLC Splitter
A blockless PLC splitter looks like a bare fiber splitter. The main differences are that the blockless one is usually terminated with fiber optic connectors and it uses a compact stainless tube package. It is also common that many bare fiber PLC splitters also use stainless tube package for the split chip.
 
Fanout PLC Splitter
Fanout PLC splitter generally uses 0.9mm buffer fiber, added with a length of ribbon fiber terminated with fanout kit behind the PLC split chip. The splitter ratios of it also come in various types. The following picture shows a 1:8 fanout version which is terminated with SC/APC connectors.
 
ABS PLC Splitter
ABS PLC splitter uses ABS plastic box to holding the splitter chip. The inbound fibers and distribution fibers are arranged on the same plate of this ABS box, which can provide easier and more flexible cabling. Except providing reliable protection, it can also be installed in a variety of boxes or enclosures. It is very commonly to install a it in a standard 19-inch rack unit.
 
LGX Box PLC Splitter
LGX Box PLC splitter looks like a MTP LGX cassette. It houses the whole splitter inside a metal box and leave fiber optic adapters for both inbound fibers and distribution fibers on its front panel. The LGX splitter can be used stand alone or be installed in the standard rack unit or fiber enclosures for better cabling.
 
Mini Plug-in PLC Splitter
Mini plug-in PLC splitter is now widely used in FTTx project, especially at the distribution points near the end users of the FTTx networks. It provides fast installation and low space requirement helping to alert the deployment of FTTs projects. Fiber pigtails for input and output can be directly connected with this passive component easily.
 
Tray Type PLC Splitter
Tray type PLC splitter also uses a space saving package form factor for better cable management. However, it uses a international 19-inch design which can be deployed in ODF for compact cable management and signal distribution. With this design, the ports on tray type splitter are clearly marked, which can reduce the faults caused by wrong connections.
 
Rack Mount PLC splitter
Rack mount PLC splitter is designed to meet the requirement of high cabling density for data centers or server room. It can be firmly installed on the data center or server racks. It is an ideal solution for high density cabling environment. fiber-mart.COM can provide PLC splitter ports up to 64 in 1U 19-inch rack. The following picture shows the details of a 1:8 rack mount one provided in fiber-mart.COM.
 
fiber-mart.COM PLC Splitter Solution
PLC splitter is a cost-effective passive optical component enabling a single network interface to be shared by two or more users. Selecting the right package form factor for it can help a lot during both the network deployment and maintaining. The above mentioned splitters in different package form factors are all being provided in fiber-mart.COM. Customized ones are also available in fiber-mart.com.

Drop Cable and Its Termination in FTTH

by www.fiber-mart.com
FTTH (fiber to the home) networks are installed in many areas covering indoor section, outdoor section, as well as the transition in between. To fulfill the cabling requirements from different areas, different types of fiber optic cable are well developed. Drop cable as an important part of FTTH network forms the final external link between the subscriber and the feeder cable. This blog post will focus on this special outdoor fiber optic cable.
 
The Basic of FTTH Drop Cable
Drop cables, as previously mentioned, are located on the subscriber end to connect the terminal of a distribution cable to a subscriber’s premises. They are typicality small diameter, low fiber count cables with limited unsupported span lengths, which can be installed aerially, underground or buried. As it is used in outdoor, drop cable shall have a minimum pull strength of 1335 Newtons according to the industry standard. Drop cables are available in many different types. The following part introduces three most commonly used drop cables divided according to the cable structure.
 
Flat Type Drop Cable, also known as flat drop cable, with a flat out-looking, usually consists of a polyethylene jacket, several fibers and two dielectric strength members to give high crush resistance. Drop cable usually contains one or two fibers, however, drop cable with fiber counts up to 12 or more is also available now. The following picture shows the cross section of a flat drop cable with 2 fibers.
 
Aerial Drop Cable is self-supporting cable, with the cable fixed to a steel wire, designed for easy and economical aerial installation for outdoor applications. This type of drop cable is fixed to a steel wire as showed in the following picture. Typical fiber counts of figure-8 Drop Cable are 2 to 48. Tensile load is typically 6000 Newtons.
 
Round Drop Cable usually contains a single bend-insensitive fiber buffered and surrounded by dielectric strength members and an outer jacket, which can provide durability and reliability in the drop segment of the network. The following shows the cross section of a round drop cable with one tight buffered optical fiber.
 
Drop Cable Connectivity Method: Splice or Connector?
It’s necessary to choose a right architecture for FTTH network from overall. However, drop cable as the final connection from the fiber optic network to customer premises also plays an important role. Thus, finding a flexible, efficient and economical drop cable connectivity method becomes a crucial part of broadband service. Whether to use a fiber optic connector, which can be easily mated and un-mated by hand or a splice, which is a permanent joint? The following will offer the answer and the solutions for your applications.
 
It is known that splice, which eliminates the possibility of the connection point becoming damaged or dirty with a permanent joint, has better optical performance than fiber optic connector. However, splice lack of operational flexibility compared with fiber optic connector. Fiber optic connector can provide an access point for networking testing which cannot be provided by splicing. Both methods have their own pros and cons.
 
Generally, splice is recommended for drop cables in the places where no future fiber rearrangement is necessary, like a greenfield, new construction application where the service provider can easily install all of the drop cables. Fiber optic connector is appropriate for applications which flexibility is required, like ONTs which have a connector interface.
 
Choosing the Right Splice Method
For splice, there are two methods, one is fusion splicing, the other is mechanical splicing. Fusion splicers have been proved to provide a high quality splice with low insertion loss and reflection. However, the initial capital expenditures, maintenance costs and slow installation speed of fusion splicing hinder its status as the preferred solution in many cases. Mechanical splicing are widely used in FTTH drop cable installation in countries, as a mechanical splice can be finished in the field by hand using simple hand tools and cheap mechanical splicer (showed in the following picture) within 2 minutes. It’s a commonly used method in many places, like China, Japan and Korea. However, in US mechanical splicing is not popular.
 
Choosing the Right Connector
For fiber optic connector, there are two types connector for drop cable connection. Field terminated connector, which contains fuse-on connector and mechanical connector, and pre-terminated drop cable, which is factory terminated with connector on the end of drop cable.
 
Fuse-on connector uses the same technology as fusion splicing to provide the high optical connection performance. However, it requires expensive equipment and highly trained technician, and more time like fusion splicing. Mechanical connector could be a replacement of fuse-on connector (showed in the following picture), if the conditions do not fit the mentioned ones. It could be a time-save and cost-save solution for drop cable termination.
 
If you have no limits in cost and want high performance termination in a time-save way, pre-terminated drop cable could be your choice. Many factories can provide you customized drop cables in various fiber types, fiber optic connector and lengths.
 
Conclusion
Customer demand for higher bandwidth will continue to drive the development of FTTH as well as its key component like drop cable. Choosing the right drop cable and drop cable termination method is as important as choosing the right network architecture in FTTH.

10G Connectivity – Comparing XFP With SFP+

by www.fiber-mart.com
Defined in 2002, XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable and protocol-independent transceiver for 10G high-speed computer network and telecommunication links. Except for XFP, there are SFP and SFP+ transceivers available for 10G connectivity. These devices plug into a special port on a switch or other network device to convert to a copper or fiber interface. So what is the difference between them? The following passage will provide a satisfying solution to you.
 
What Is XFP?
XFP is 10 Gigabit transceiver operating at wavelengths of 850nm, 1310nm or 1550nm. This module combine transmitter and receiver functions in one compact, flexible, and cost-effective package. The physical dimensions of the XFP transceiver are slightly larger than the original small form-factor pluggable transceiver (SFP). XFP transceiver modules are available with a variety of transmitter and receiver types including the SR, LR, ER and ZR. The maximum working distance of XFP SR is 300 meters. 10GBASE-LR XFP transceivers have a wavelength of 1310nm and a transmission distance up to 10 km. For example, XFP-10G-L-OC192-SR1 covers a distance of 10km with LC connectors. XFP-10GLR-OC192SR is Cisco XFP 10GBASE-LR/-LW operating at wavelength of 1310nm over singlemode fiber with a links length of 10km. Both 10GBASE-ER XFP and 10GBASE-ZR XFP modules have a wavelength of 1550nm, and the maximum transmission distance of 40km and 80km, respectively.
 
What Is SFP/SFP+?
SFP is most often used for Fast Ethernet of Gigabit Ethernet applications and can support speed up to 4.25Gbps. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is specified by the SFP transceiver multi-source agreement. The standard SFP transceiver, SFP+ supports speeds of 10Gbps or higher over fiber. The SFP+ product family includes cages, connectors, and copper cable assemblies. It is also similar to the performance requirements of SFF-8431 and also supports 8G Fiber Channel and 10G Ethernet applications. Take 46C3447 as an example, it is 10GBASE-SR SFP+ that can support a distance of 300m over OM3 cable.
 
What’s the Difference Between XFP and SFP+?
First of all, both of them are 10G transceiver modules and can contact with other types of 10G modules. The primary difference between SFP+ and the slightly older XFP standard is that the SFP+ moves the chip for clock and data recovery into a line card on the host device. This makes SFP+ smaller than XFP, enabling greater port density. Because of the smaller volume, SFP+ transfer signal modulation function, serial/deserializer, the MAC, clock and data recovery (CDR) and electronic dispersion compensation (EDC) function from the module to the Lord on the card. In addition, SFP+ compared to XFP, is a more compact factor package. The cost of SFP+ is also less than that to the XFP, X2 and XENPAK. It can connect with the same type of XFP, X2 and XENPAK as well. Therefore, SFP+ is more popular than XFP for 10G network.

Are You Ready for Embracing 100G Ethernet?

by www.fiber-mart.com
Ethernet as the networking standards, enables computers to locally connect to each other, which is the ultra-strong backbone to the many networks we use every day. Although most of the Ethernet market is still running around 1 Gbqs or 10 Gbqs, there is a strong interest in higher data rates. Many hardware vendors like Cisco, Finisar, Huawei and Brocade have recently announced support for 100 Gigabit Ethernet and telecom vendors around the world have also shown interest in launching 100G networks. All these events shows the sign of the advent of 100 Gigabit Ethernet in the commercial segment. However, is it necessary to move to 100G now? Or should the 100g migration be a smooth one just as the IEEE has made when moving to 40G? This article will highlight the reasons and solutions of upgrading to 100G.
 
Why Move to 100G?
 
Most enterprises today are encouraging telecommuting and promote real-time, high-definition, high-quality voice and video solutions. All these require a huge bandwidth capacity. Additionally, 100G implementations offer an effective means to operate seamlessly within an existing 10G network infrastructure, avoid the need for additional optical amplifiers, dispersion compensators or regenerators. 100G is today’s choice to scale networks in a way that delivers the required capacity in the most efficient manner, readying the network for tomorrow’s bandwidth crunch.
 
Another interesting point is the efficiency of 100G Ethernet compared to link aggregation that is used today. As of now, a 10 x 10G Ethernet link aggregation can not give a throughput of up to 100 Gbps. This limitation can be overcome with a true 100G connection which can give a 100Gbps bandwidth, thus allowing high capacity links to scale even further. Considering all these, if not this year or the next, 100G will be widely adopted soon.
 
Last but not the least, the industry have come together in order to create a healthy 100G ecosystem, which will be beneficial for the entire community. This broad inclusion will result in a fast introduction of 100G solutions that will meet industry performance, size, cost, and power requirements. If the cost drive is right, once 100G is standardized and commercially available, network operators will quickly capitalize 40G investments and adopt 100G transmission for their future deployments.
Migrate to 100G with 100G Transceiver Modules
 
There are several form factors for supporting 100GbE including CFP, CFP2, CFP4, QSFP28 and CPAK. The following will make a clear introduction to all of them.
 
CFP Transceiver
 
The CFP is the very first 100G transceiver for the transmission of high-speed digital signals, the C stands for the Latin letter centum (means 100). The CFP module was designed after the SFP interface, but is significantly larger to support 100 Gbqs using 10 x 10 Gbit/s lanes in each direction (RX, TX). The optical connection can support both 10 x 10 Gbit/s and 4 x 25 Gbit/s variants of 100 Gbit/s interconnects. There are four common types of CFP transceiver modules, such as 100GBASE-SR10 in 100 meter MMF, 100GBASE-LR10 and 100GBASE-LR4 in 10 km SMF reach, and 100GBASE-ER10 and 100GBASE-ER4 in 40 km SMF reach respectively.
 
As improvements in technology have allowed higher performance and higher density, which drives the development of the CFP2 and CFP4 specifications. While CFP, CFP2 and CFP4 are electrical similar, they specify a form-factor of 1/2 and 1/4 respectively in size of the original specification. Note that CFP, CFP2 and CFP4 modules are not interchangeable, but would be inter-operable at the optical interface with appropriate connectors.
 
QSFP28 Transceiver
 
QSFP28 is the same footprint as the 40G QSFP+ module. Just as the 40G QSFP+ module is using four 10Gbps lanes, the 100G QSFP28 is implemented with four 25Gbps lanes. In all QSFP versions, both the electrical lanes and the optical lanes operate at the same speed, eliminating the costly gearbox found in CFP, CFP2, and the CPAK. The QSFP28 module has an upgraded electrical interface to support signaling up to 28Gbps signals, yet keeps all of the physical dimensions of its predecessor. As QSFP28 technology becomes even maturer, QSFP28 transceivers will become more and more popular in 100G optics market. The above image shows a QSFP-100G-SR4-S. it is Cisco 100GBASE-SR4 QSFP28 transceiver module.
 
100GBASE-SR4 QSFP28 transceiver and 100GBASE-LR4 QSFP28 transceiver are the two main types of the QSFP28 transceivers. The former is specified to operate over multimode fiber (MMF) with the maximum link length of 70m on OM3 and 100m on OM4, while 100GBASE-LR4 QSFP28 is standardized to work through single-mode fiber (SMF), able to realize 10km link length.
 
QSFP28 vs. CFP
 
QSFP28 and CFP are the two common 100G optical transceivers available on the market. As noted before, CFP is the first-generation 100G transceiver. It is the common scene that QSFP28 makes an appearance and CFP takes a bow, which reflects the trend in the industry to aggressively bring 100GE density up and costs down. CFP4 is half the width of CFP2, which is half again the width of CFP. QSFP28 has the same footprint and faceplate density as QSFP+ and is just slightly smaller than CFP4. Theoretically, QSFP28 seems to have the density advantage over CFP4, but CFP4’s higher maximum power consumption gives it the advantage on longer reach optical distances. However, the CFP is much more expensive than QSFP28 and will not be used for lower speeds because of the high cost.
 
CPAK Transceiver
 
CPAK is another newcomer to supporting 100G network. This is a proprietary form factor from Cisco but the interfaces demonstrated are IEEE standards and will interoperate with the same interfaces supported by other form-factors. Together, these solutions will deliver the smallest form-factor, most efficient 100-Gbps optical transceiver portfolio in the industry. Cisco CPAK will be available in several IEEE-standard optical interfaces.
 
Conclusion
 
Within the next several years, 100G is doom to become the dominant backbone technology in terms of its high capacity over 10G and surpassing would-be high-speed contender 40G. Of course, we must count on the components and systems suppliers to build products that meet technical and economic requirements while allowing a smooth migration to the 100G infrastructure that is being put in operation today.
