Description

2.488Gbps Compact Bi-Di SFP Transceiver 1490nm TX 1310 nm RX 20km

Description

The GCS-B4325-B4325-20C transceiver is high performance, cost effective module where both ports are bi-directional, each port supports 2448Mbps throughput and 20km transmission distance with SMF.

The two independent channel transceiver unit consists of three sections: a high quality 1490nm DFB laser transmitter, a high reliable 1310nm PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C interface as specified in the MSA SFF-8472.

The transceiver is fully compatible with Compact SFP Multi-Source Agreement (MSA).
