25G SFP+ Duplex LC 1310nm 10KM DFB Optical Module Transceiver
25G SFP+ Duplex LC Fiber Transceiver 1310nm 10KM DFB Optical Module Transceiver
25Gb/s SFP28 Transceiver SFP28-28G-LR dual fiber singleimode 10km 1310nm LC DDM
Description
The NuFiber SFP-25G-LR is is a single-channel, pluggable, fiber-optic SFP28 transceiver module for 25G Ethernet and InfiniBand EDR applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125Gb/s up to 10km. This module is designed to operate over single mode fiber systems using a nominal wavelength of 1310nm. The electrical interface uses a 20 contact edge type connector. The optical interface uses duplex LC receptacle. This module incorporates Gigalight Technologies proven circuit and technology to provide reliable long life, high performance, and consistent service.
