D-Link DEM-433XT Compatible 10GBASE-ER SFP+ Transceiver Module (SMF, 1550nm, 40km, LC, DOM)
This D-Link DEM-433XT compatible SFP+ transceiver supports 10GBase-ER (10.31 Gbps) and 10GBase-EW (9.95 Gbps) throughput up to 40km over single-mode fiber (SMF). It operates at a 1550nm wavelength and features an LC duplex connector. Following various industry standards, the transceiver complies with SFP+ MSA, SFF-8431, SFF-8432, and IEEE 802.3ae. That ensures seamless interoperability and flexibility within a multi-vendor network. The 10GBase-ER SFP+ is specially designed to address the challenges of long-distance connections in 10G networks. It delivers a low-cost solution for long-reach fiber link interconnectivity, such as data center interconnect (DCI), campus networks, metro area networks, telecom networks, and enterprise backbone networks. Most importantly, we code and test each SFP+ module to ensure it works with the 10G SFP+ port of D-Link network switches, routers, servers, and network interface cards (NICs).

Key Features
Optimal Performance and Quality for 10G Networks
Featuring a built-in Semtec/Macom chip and reliable cooled EML laser from global leaders, the 10G SFP+ ER module delivers low power consumption and stable optical links for high-speed single mode networks like 10G Ethernet/Fibre Channel. You can rest assured regarding quality and warranty.
Intelligent DOM/DDM for Reliable Networks
With built-in DOM/DDM function, the 10G SFP+ ER module allows users to monitor the fiber link operating parameters in real-time. It will enable you to troubleshoot when problems occur quickly, ensuring a reliable optical network.
Green Network, Extending Switch Lifespan
High energy consumption and heat generation are significant threats to network stability. Our 10G SFP+ ER transceiver features a low-power design (<1.5W), effectively reducing heat generation and preventing performance degradation caused by temperature increases. And finally, extend the life of your switch and server, and help build a green and efficient 10G network.
