It operates copper SFP 1.25Gb/s optical transceivers

Copper transceiver is high performance, cost effective module compliant with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE 82. 3-22 and IEEE 82.3ab, which supporting 1Mbps data- rate up to 1 meters reach over unshielded twisted-pair CAT 5 cable. Copper SFPs enable system manufacturers to populate SFP ports with either copper or optical transceivers. 1000Base-T copper SFP is used for copper networks, which refers to GbE over copper, primarily Category 5, 5E, and, increasingly, Category 6 twisted-pair cable. Typical 1000Base T SFP includes Cisco GLC T and SFP 1.25Gb/s,these SFP modules are used in Gigabit networks and they are fully compatible with 1000Base-T. SFP GE T is the copper SFP that are with extended working temperature and DOM support It operates on standard Category 5 unshielded twisted pair copper cabling of up to 100m length. This transceiver is also compliant with RoHS, SFP MSA, FCC 47 SFR Part 15, Class B and SONET/SDH recommendations for OC-48 specifications. It is widely used in serial telecom and datacom applications.
