SFP Gigabit CWDM modules, 1471-1611nm, 40Km range, Digital Diagnostic

Product description
The SFS-7040 series CWDM SFP modules have a 1.25Gbps (Gigabit) rate. Transceivers operate on 9/125um single-mode fiber for up to 40Km, using special CWDM channels (1471nm to 1611nm, in steps of 20nm). SFP CWDM modules support DD (Digital Diagnostic) functions. Three operating distances are available for Gigabit CWDM modules: 40Km, 80Km and 120Km. For 120Km please contact us for quotations.

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 the special CWDM optical modules. Also, the CWDM SFP modules can be installed in dedicated managed CWDM solutions, like the Sigma Links series.

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.
