D-Link DEM-Q28X10Q-4WDM Compatible 100Gbps QSFP28 100GBASE-4WDM 1310nm 10km SMF Duplex LC DDM/DOM Optical Transceiver Module D-Link DEM-Q28X10Q-4WDM compatible optical transceiver is a parallel 100Gbps Quad Small Form-factor Pluggable QSFP28 module for use in 100GBASE Ethernet network. QSFP28 4WDM provides 103.1Gb/s throughput up to 10km over single-mode fiber (SMF) with host FEC using 1271nm, 1291nm, 1311nm, 1331nm wavelength. This transceiver is fully compliant with QSFP28 Multi-Source Agreement (MSA), IEEE 802.3 100GBASE-4WDM and CAUI-4 standard. Its electrical interface is MSA compliant 38-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex QSFP28 transceiver implements 4 independent 25.78125Gbps transmit and receive signal channels in each wavelength for an aggregate 103.125Gbps data rate. Built-in Digital Diagnostic Monitoring/Digital Optical Monitoring (DDM/DOM) support is present for real-time performance monitoring via 2-wire (TWI/I2C) interface. Our modules are factory pre-programmed for compatibility, perform alternatively to genuine D-Link DEM-Q28X10Q-4WDM transceivers.
