1000BASE CSFP Dual BIDI 40km TX1550 RX1310 SM Transceiver LC DOM
Description
This GCS-B5312-B5312-40C CSFP Transceiver is high performance and high stability product operating in standard temperature,provides 1000Base-BX 2-Channel throughput up to 40km over single-mode fiber (SMF) using a nominal wavelength of 1550nmTx/1310nmRx via an LC connector.
For each Channel, The transceiver consists of three sections: a 1550nm DFB laser transmitter, a 1310nm 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.For further information, please refer to SFP MSA
