Description

Fiberxon 1310nm transponders are intended for 1310nm system applications with reaches of up to 7km and 20km, which is designed to provide high optical performance for SONET OC-192 / SDH STM-64. The transmitter converts the electrical data into 10Gbit/s optical signal, which uses 1310nm externally EA modulated laser with specified driving circuit. At the receiving side, the incoming data stream is received at 10Gb/s PIN receiver, which converts it into a 10Gb/s electrical data stream. The MUX section multiplexes 16 parallel 622Mb/s electrical channels into a 10Gb/s series data stream and sent it to the trans mitter. And the DEMUX section demultiplexes the 10Gb/s electrical data stream into 16 parallel 622Mb/s electrical channels. The parallel data is sent out to and get from the 300-pin MSA (Multi Source Agreement) compliant connector. The transmitter and receiver reference clock rates are selectable for divide by 16 or 64.

This section details the specif ic functions, capabilities, and limitations of each. Note that all clock rates sh own are at STM-64/OC-192 rate, but should be scaled appropriately for other data rates. The LVPECL TxREFCLK, provided via the 300-pin interface, may be at 1/16 or 1/64 of the transmitted serial data rate. The TxREFCLK must be synchronous with t he TxPICLK. There are several approaches to ensure this synchronous relationship. The two most common are 1) Locking the TxPICLK to the TxPCLK out of the transponder
