D-Link DEM-Q28X40Q-ER4 Compatible 100Gbps QSFP28 100GBASE-ER4 1310nm 40km SMF Duplex LC DDM/DOM Optical Transceiver Module D-Link DEM-Q28X40Q-ER4 compatible optical transceiver is a parallel 100Gbps Quad Small Form-factor Pluggable QSFP28 module for use in 100GBASE Ethernet network. QSFP28 ER4 provides 103.1Gb/s throughput up to 25km-40km over single-mode fiber (SMF) with host FEC using 1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm wavelength. This transceiver is fully compliant with QSFP28 Multi-Source Agreement (MSA), IEEE 802.3ba 100GBASE-ER4 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-Q28X40Q-ER4 transceivers.
