D-Link DEM-311GT Compatible 1000BASE-SX SFP 850nm 550m MMF LC DOM Optical Transceiver Module


D-Link DEM-311GT compatible optical transceiver is a dual fiber 1000Mbps Small Form-factor Pluggable SFP module for use in 1000BASE Ethernet. SFP SX provides 1Gb/s throughput up to 550 meters over OM2 multi-mode fiber (MMF) using 850nm wavelength. This transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3z 1000BASE-SX and SERDES standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP transceiver features highly reliable VCSEL transmitter and PIN photo detector to offer high performance interconnection at 1 Gbps data rate. Built-in Digital Diagnostic Monitoring (DDM) support is present for real-time performance monitoring via 2-wire Interface (TWI/I2C). Our modules are factory pre-programmed for compatibility, perform identically to original D-Link DEM-311GT transceivers.
