The Gigalight 100G QSFP28 CLR4 10km optical transceiver (GQS-SPO101-CLR4CB) is designed for 100G-CLR4 Ethernet links reach up to 10km over Single-Mode Fiber (SMF).
The module converts 4 input channels of 25Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data.
The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm and 1331nm as members of the CWDM wavelength grid defined in the 100G-CLR4 specifications. The high-performance uncooled CWDM DFB transmitters and high-sensitivity PIN receivers provide superior performance for 100G Ethernet applications up to 10km links.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP MSA. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The Gigalight 100G QSFP28 CLR4 10km optical modules are qualified under case temperature 85°C and humidity 85% @500 hours (the variation of TX ≤ 2.5dBm, RX ≤ 1.5dBm).
