Description

This product is a transceiver module designed for optical transmission applications over both MMF and SMF with transmission distances of up to 100m on MMF (OM3) and 2km on SMF. The module converts 4 inputs channels (ch) of 25Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 100Gb/s optical transmission.

Reversely, on the receiver side, the module optically de-multiplexes a 100Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.

The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface.

The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

For applications over OM3/OM4 MMF, MMF cables are directly connected to the LC connectors of QSFP28 LX4 module and optical signal is directly launched from the transmitter into the MMF cable as shown in Figure 2. For applications over SMF, the module is used as a QSFP28 CWDM4 module and SMF cables are directly connected to the LC connectors of the module as shown in Figure 3.
