TK-B3424-3LCD20 1.25Gbps SFP Bi-Directional Transceiver, 20KM Reach Tx1310nm/Rx1490nm

The SFP-BIDI transceivers are high-performance, cost-effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 20KM transmission distance with single-mode fiber.

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 specifications.
