Fiber SFP Module 100G 10KM QSFP28 Transceiver Single Mode Duplex LC Connector
100G QSFP Transceiver Advantages
► 4 lanes MUX/DEMUX design
► Integrated LAN WDM TOSA / ROSA for up to 10 km reach over SMF
► Built-in digital diagnostic functions
► Support 100GBASE-LR4 for line rate of 103.125Gbps and OTU4 for line rate of 111.81Gbps
Applications

► Wide Area Network (WAN)
► Ethernet switches and router applications
Overview
The LNK-QSFP28-LR4-10 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) of 25.78 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.
