155Mbps Compact Bi-Di SFP Transceiver 1310nm TX 1550nm RX 40km
Description
This 2 Fiber 100Base CSFP transceiver is an ultra-low power (power consumption < 1.3W), high performance and high stability product operating in commercial temperature, supporting 155Mbps and 40km transmission distance with SMF cable.
The transceiver consists of three sections: a DFB 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 Compact SFP Multi-Source Agreement (MSA) and SFF-8472.
