Customized SFP Transcceiver 1000BASE-LX/LH SFP 1310nm 20km DOM LC SMF Optical Module
Product Descriptions
1000BASE-LX/LH SFP 1310nm 20km DOM LC SMF Transceiver Optical modules are high performance, cost effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps 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) and MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
