The capacity of SFP-7120-55 module is 1.25Gbps (Gigabit rate). The transceiver is able to work on long-haul 9/125um single-mode fiber for up to 120Km distance. The fiber standard for SFP-7120-55 is 1000Base-ZHX. SFP module supports DD (Digital Diagnostic) functions.

All the managed FRM220-1000MS and FRM220-1000TS, as well as unmanaged FMC-1001S and FRM220-1000DS 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.
