Generic SFP1G-LH-31 Compatible 1000BASE-LX SFP Transceiver Module (SMF, 1310nm, 20km, LC, DOM)<\/span><\/h2>\n

Optcore’s 1000BASE-LX SFP transceiver offers a low-priced replacement for Generic SFP1G-LH-31 without lowering the quality of your fiber optic network connectivity. It is a new SFP module made by a third-party manufacturer rather than a Brand to provide a cheaper transceiver with the same high quality. This module supports 1G connectivity up to a maximum distance of 20km over single mode fiber (SMF) at a wavelength of 1310nm. Moreover, it has been programmed and tested to work as the original Generic SFP1G-LH-31. It suits brand network switches, routers, firewalls, security gateways, fiber media converters, servers, NAS, accelerator cards, network adapters, and interface cards (NICs).<\/p>\n
