SFP is short for small form-factor pluggable. It’s a compact, hot-pluggable transceiver used for telecommunication and data communications. The form factor and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP transceivers can support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP transceivers are upgraded from the traditional version with more flexibility but a smaller size.
Sometimes you may encounter the affairs like the installation and removing of a SFP transceiver. The following will tell you how to install and remove a SFP transceiver.
Install a SFP Transceiver
The following steps tell how to install a SFP transceiver:
Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis. SFP modules are static sensitive. Wear an ESD-preventive wrist strap so that it can prevent ESD damage.
Remove the dust cap and save for future use.
Ensure the SFP transceiver in the correct orientation for your device.
Insert the SFP module into the socket. Be sure that the SFP module is in the right position before inserting.
Observe the LED. If the LED turns green, it means the transceiver and the device establishes link successfully. While if the LED is off, there may be an installing problem with the adapter.
Remove a SFP Transceiver
To remove a SFP transceiver (see the picture), the following procedures you should bear in mind:
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
Disconnect the network cable from the SFP transceiver.
Remove the SFP transceiver carefully from the module slot.
Place the removed the SFP module in a static shielding bag.
The above is about how the installation and removing of a SFP transceiver. One of the most famous brands Cisco SFP transceiver, which offers a convenient and cost effective solution in the adoptions of data center, campuses, metropolitan area, ring networks and storage networks is also suitable to these steps in applications.
At last, SFP transceivers are dust sensitive. So store the devices with plugs to avoid getting dust into the installed optical bores. And clean the optic surfaces of the fiber optical cables before the insertion. But you should better not insert or remove a SFP module until it’s necessary. Because it’s not good for keeping the useful life with repeated removals or insertions of a SFP transceiver.
