SFP-7020-31 SFP module has a 1.25Gbps (Gigabit) transmission rate. The transceiver is able to work on 9/125um single-mode fiber for up to 20Km distance. The fiber standard for SFP-7010-31 is 1000Base-LX. Transceiver includes Digital Diagnostic Monitoring features (DDM) reporting back operating temperature and signal levels for laser and photodiode, information that can be processed by compatible DDM networking devices.
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. These SFPs have been tested and found 100% compatible with various Ethernet switches from major manufacturers like: Cisco, Nortel, Extreme, ZyXEL, D-Link or Netgear.
