This SFP transceiver is a high performance, cost effective modules supporting data-rate of 1. 25Gbps and 20km transmission distance with SMF. The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA). 1G SFP optical transceiver modules for multi-mode and single-mode in distances ranging from 300 meters up to 80km with a limited lifetime warranty. FS gigabit ethernet transceiver solutions provide fibre or copper options including 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-T etc. 30-Day. Optcore's 1000BASE SFP transceiver is suitable for 1G Ethernet and fiber channel applications. Therefore, it is sometimes called 1G SFP or GE SFP module.
