SFS-7040-L31 - 1000Base-LHX, single-mode, 40Km, 1310nm SFP module

Product description
The capacity of SFS-7040-L31 module is 1.25Gbps (Gigabit rate). The transceiver is able to work on 9/125um single-mode fiber for up to 40Km distance. The fiber standard for SFS-7040-L31 is 1000Base-LHX. SFP module supports DD (Digital Diagnostic) functions.

All the managed FIB1-1000ES and FIB1-1000TS as well as unmanaged FMC-1000ES and FIB1-1000DS series of standalone Gigabit media converters can be equipped with miniGBIC/SFP optical modules.

SFP's or miniGBIC modules are extremely versatile, working with any active equipment that support the SFP type of interface: Ethernet switches, routers and any other networking equipment. Our SFPs have been tested and found 100% compatible with various Ethernet switches from major manufacturers like: Cisco, Nortel, Extreme, ZyXEL, D-Link or Netgear.
