Product Descriptions
GFC-OLSB45(54)25L-C(I)D80, The SFP-BIDI transceivers are high performance, cost effective modules supporting dual data-rate of 2.5Gbps/2.125Gbps and 80km transmission distance with SMF.The transceiver consists of three sections: a DFB laser transmitter, a APD photodiode integrated with a trans-impedanc e 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.

Notes:
- TD+/- are internally AC coupled with 100Ω differential termination inside the module.
- Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.
- RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.
