Fiber-Optic SFP Modules

Some fiber-optic SFP modules use LC-type connectors, as shown in

Protect your fiber-optic SFP modules by inserting clean dust plugs into the SFP modules after you

Caution

remove the cables. Be sure to clean the optic surfaces of the fiber-optic cables with a soft antistatic cloth

before you reconnect them to another SFP module. Avoid getting dust and other contaminants into the

optical bores, as the optics do not work correctly when obstructed with dust.

SFPs provide duplex single-mode and multimode connections in supported devices. For cable

specifications for fiber-optic SFP module ports, refer to:

When using shorter distances of single-mode fiber cable, you might need to insert an inline optical

Note

attenuator in the link to avoid overloading the receiver.

When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB) or

10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the

1000BASE-ZX SFP module at each end of the link.
