Description

Fiberxon 622Mbps Spring-latch SFP transceiver is high performance, cost effective module that supports data-rate of 622Mbps and transmission distance from 15km to 80km.

The transceiver consists of two sections: The transmitter section incorporates a FP or uncooled DFB laser, and the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All modules satisfy class I laser safety requirements.

The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver.

An enhanced Digital Diagnostic Monitoring Interface Compatible with SFF-8472 has been incorporated
into the transceivers. It allows real time access to the transceiver operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage by reading a built-in memory with I2C interface. For further information, please refer to SFF-8472 Rev 9.5.
