D-Link DEM-S2810LR Compatible 25Gbps SFP28 25GBASE-LR 1310nm 10km SMF Duplex LC DDM/DOM Optical Transceiver Module D-Link DEM-S2810LR compatible optical transceiver is a dual fiber 25Gbps Small Form-factor Pluggable SFP28 module for use in 25GBASE Ethernet network. SFP28 LR provides 25.78Gb/s throughput up to 10km over single-mode fiber (SMF) with host FEC using 1310nm wavelength. This transceiver is fully compliant with SFP28 Multi-Source Agreement (MSA), IEEE 802.3cc 25GBASE-LR and 25GAUI standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP28 transceiver features highly reliable DML transmitter and PIN photo detector to offer high performance interconnection at 25.78125Gbps 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-S2810LR transceivers.
