The LSZH Cables, Ribbon Cables And Indoor Outdoor Cables

by www.fiber-mart.com
With the creation of modern technology, many new networks will choose to use bulk fiber cable instead of traditional copper based cables to increase the capability and speed of the network.Many different types of fiber optic cables in our life. They are generally used in different places. Under different conditions to select the appropriate cable.From fiber-mart.com, they inculding the Indoor Cables, Outdoor Cables, FTTH Cables, Armored Cables, LSZH Cables and some special cables. They are various at Aerial Cables, Building Cables, Direct buried cables, Duct Cables, Underwater/Submarine Cable. Some of our optical fiber comes with steel tube and steel wire armoring, suitable for sea, lake and river applications. Customers have the flexibility to choose a cable plant to best fit their needs. Only optical fiber that meets or exceeds industry standards is used to ensure quality products with best-in-class performance.So many cable in it, but do you know which cable you need.Tell you some info about LSZH fiber cable,Ribbon fiber cable,Indoor Outdoor Cable.I think it can help you choose the nice cable.
 
What is Low Smoke Zero Halogen (LSZH) ?
 
Low Smoke Zero Halogen (LSZH) is a type if cable jacketing made of polypropylene that gives off limited smoke and no halogens when come across fire or strong heat. LSZH cable jacketing consists of thermoplastic or thermoset compounds that produce limited smoke and no halogen when come across high sources of heat, e. grams. flare.Low Smoke Zero Halogen cable can be called LSF (low smoke and fume), LSHF (low smoke halogen free), and LS0H (low smoke zero halogen).
 
Why to used the LSZH Cables ?
 
Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted during combustion. This type of material is typically used in badly ventilated areas such as planes or railroad cars. Low smoke zero halogen is becoming very popular and, in some cases, a requirement where the protection of men and women and equipment from toxic and corrosive gas is very important.
 
They don’t produce a dangerous gas/acid combination in case of fire. LSZH patch cords are for utilization in patching environments with poor air circulation where personnel and equipment may be exposed to corrosive fumes and toxins during combustion. The cable jacket for these wires is designed to minimize the release of halogen fumes and toxicants into the air, reducing the potential of hazardous contact in occupied spaces. LSZH cables are mainly used in The european countries.
 
What is Ribbon Fiber Cable ?
 
Ribbon Fiber Cable is preferred where high fiber counts and small diameter cables are needed. This cable has the highest packing density, since all the fibers are laid out in rows in ribbons, typically of 12 fibers, and the ribbons are laid on top of each other. Not only is this the smallest cable for the most number of fibers, it’s usually the lowest cost. Typically 144 fibers in ribbons only has a cross section of about 1/4 inch or 6 mm and the jacket is only 13 mm or 1/2 inch diameter! Some cable designs use a “slotted core” with up to 6 of these 144 fiber ribbon assemblies for 864 fibers in one cable! Since it’s outside plant cable, it’s gel-filled for water blocking or dry water-blocked. These cables are common in LAN backbones and data centers.
 
Where can used the Ribbon Cables?
 
Ribbon cables are usually seen for internal peripherals in computers, such as hard drives, CD drives and floppy drives. On some older computer systems (such as the BBC Micro and Apple II series) they were used for external connections as well. Unfortunately the ribbon-like shape interferes with computer cooling by disrupting airflow within the case and also makes the cables awkward to handle, especially when there are a lot of them; round cables have almost entirely replaced ribbon cables for external connections and are increasingly being used internally as well.
 
What is Indoor Outdoor Fiber Optic Cable?
 
Indoor Outdoor Fiber Optic Cable is designed to meet both the stringent environmental requirements typical of outside plant cable AND the flammability requirements of premise applications. Ideal for applications that span indoor and outdoor environments. By eliminating the need for outside to inside cross-connection, the entire system reliability is improved and with lower overall installation costs.
 
Ideal for applications that span indoor and outdoor environments, Indoor/outdoor cable can eliminate the need for building entryway splice points, saving both time and money. Outdoor/Indoor cables combine the flame resistance and safety features of an indoor riser or plenum cable with the durability that is critical for OSP use. The result is a unique, dual-purpose cable that can save time and money by allowing OSP applications to flow seamlessly indoors, using a single cable and no splices.
