100BASE Compact SFP Dual Bidirectional Optical Fiber Transceiver TX1310nm RX1550nm LC 20km DOM

100BASE CSFP Dual Bidirectional Optical Fiber Transceiver TX1310nmRX1550nm LC 20km DOM


Description


The GCS-B3502-B3502-20C is a high performance CSFP transceiver module for Fast Ethernet data links.

It is specifically designed for the high performance integrated two bi-directional links on a duplex single-mode fiber, each link supports 155Mbps throughput and 20km transmission with LC interface.

For each channel this BIDI transceiver unit consists of a 1310nm DFB laser transmitter and a 1550nm PIN photodiode, all module satisfy Class 1 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 specified in the SFP MSA SFF-8472.

This CSFP LX Transceiver is fully compliant to compact Small Form-Factor Pluggable (CSFP) MSA option 2 and CE/RoHS certified.
