2x 155Mbps 1310nm 1490nm Compact SFP BIDI Transceiver LC 40km DOM
2x 155Mbps TX_1490nm/RX_1310nm CSFP BIDI Transceiver LC 40km DOM
Description
The GCS-B4303-B4303-40C compact small form-factor pluggable (CSFP) is a version of SFP with the same mechanical form factor allowing two independent bidirectional channels per port.
It include two BOSA in one SFP port, each BOSA consists of a high quality 1490nm DFB laser transmitter and high sensitivity 1310nm PIN photodiode, providing 155Mbps throughput with 40km link transmission.
It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C interface specified in the SFP MSA SFF-8472,real time monitors of temperature, supply voltage, laser bias current, laser average output power and receiving output power are provided.
This two-fiber CSFP transceiver is fully compliant to compact Small Form-Factor Pluggable (CSFP) MSA option 2 and CE/RoHS certified.
