100G QSFP28 LR4 optical transceiver module, support 100Gb/s and up to 10 km transmission on SM fiber, it works in high-speed IDC connection solutions, and so on.
Features
100G LR4 10km QSFP28 Transceiver Hot Pluggable, LAN-WDM4 Duplex LC Connector, Single mode
The QSFP28 100G LR4 10K RQ-100G-LR4 is a transceiver module designed for 10km optical communication applications. The design is compliant to 100GbASE-LR4 of the IEEE 802.3-2012 Clause 88 standard IEEE 802.3bm CAUI-4 chip to module electrical standard ITU-T G.959.1-2012-02 standard . The module converts 4 inputs channels (ch) of25.78 Gbps to 27.95Gbps electrical data to 4 lanes 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 lanes signals, and converts them to 4 lanes output electrical data.
