100BASE Dual BIDI CSFP Optical Fiber Transceiver TX1310nm RX1490nm LC 20km DOM
100BASE Dual BIDI CSFP Optical Fiber Transceiver TX1310nmRX1490nm LC 20km DOM
Description
The 100Base dual Bi-directional CSFP optical transceiver is a version of SFP with the same mechanical form factor allowing two independent bidirectional channels per port.
For each channel, this 100BASE CSFP transceiver unit consists of three sections: a 1310nm DFB laser transmitter, a 1490nm 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 SFF-8472, which provides real time monitors of temperature, supply voltage, laser bias current, laser average output power, receiving output power and etc.
It’s idea for Fast Ethernet, 100Base-X applications.
