This document describes the main features and functionality of the evaluation module (EVM) board for the
devices.
The ONET1131EC is a 11.7-Gbps transceiver with an integrated limiting amplifier and a modulator driver.
The EVM can be used to evaluate the performance of the parts in conjunction with an electroabsorptive
modulated laser (EML) transmit optical subassembly (TOSA) and a receive optical subassembly (ROSA)
in standard XMD-compliant packages.
The EVM is controlled with a graphical user interface (GUI).
Throughout this document, the images shown may represent the ONET1130Ex. Those images are
representative of the boards and parts on the ONET1131EC.
