SFP-10G-LR-1310nm 20km LC DDM Optical Transceiver Module CISCO, HUAWEI, H3C, Juniper, D-link, HP, IBM, dell, Mikrotik, Aruba,Quidway Compatible This 10GBase-LR 1310nm SFP+ transceiver is designed to transmit and receive optical data over single mode optical fiber for link. This is a industrial SFP optical module. It uses duplex single mode optical fiber and the speed rate can up to 1. 25Gbps, transmission distance up to 20km. This product need to use in pair and match up with fiber converter and optical Ethernet switch with SFP port, it can be used in Ethernet. This Generic SFP-1G-LX compatible SFP module supports 1000BASE-LX/LH connectivity over single mode fiber cable (SMF). It supports a link distance of 10km to 20km on SMF fiber, or 550m on MMF fiber (need to be used along with mode conditioning patch cable). 25Gbps data rate and use a 1310nm wavelength to deliver stable long-distance. Our 1000BASE-EX SFP 20km transceiver delivers extended-reach gigabit connectivity for metro networks.
