RealSea’s 100G QSFP28 ER4 Lite optical Transceiver integrates receiver and transmitter path on one module. In the transmit side, four lanes of serial data streams are recovered, retimed, and passed to four laser drivers. The laser drivers control 4-EML with center wavelength of 1296 nm, 1300nm, 1305nm and 1309 nm.The optical signals are multiplexed to a single–mode fiber through an industry standard LC connector. In the receive side, the four lanes of optical data streams are optically de-multiplexed by the integrated optical demultiplxer. Each data stream is recovered by a APD and trans-impedance amplifier, retimed. This module features a hot-pluggable electrical interface, low power consumption and MDIO management interface. The product compliant with QSFP28 Multi-Source Agreement (MSA) and IEEE 802.3bm.
