Sfp Module 1.25G 40km T1550 R1310 Sfp Transceiver Epon Sfp Optical Module Single Mode Fiber Sc Network Fttx Solution
The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 10km 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.
