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.
