RealSea’s QSFP28-100G-LR4 optical transceivers are based on 100G Ethernet IEEE 802.3ba standard. The QSFP28 transceiver converts 4 inputs channels of 25Gb/s electrical data to 4 LAN-WDM 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 LAN-WDM channels signals, and converts them to 4 channel output electrical data.
