Transceiver Driver slot module of FOTS system is an efficient module for the characterization of SFP type transceiver and the test of optical line or components. This module is a kind of Small Form Factor Pluggable(SFP) host board that can be used to test SFP transceiver modules to define the modules’ performance. The transceiver driver slot has two SFP cage and 20-pin SFP connector sets to mount and control two SFP transceivers simultaneously.

Using the built-in high-speed processor and its programmed internal PRBS pattern generation circuit, the SFP can be modulated up to the rate of 1.25 Gbps in various pseudo random patterns. The PRBS pattern generation and BERT function of this module can be used to perform FTTx-PON test and optical line or system test. This instrument provides wide range of applications and attractive solution of performance in SFP test and FTTx-PON test.
