This Korenix SFPGSX compatible SFP module supports 1000BASE-SX connectivity over multimode fiber cable (MMF). It supports a link distance of 550m via 50µm OM2 or 220m via 62.5µm OM1 fiber. This multimode transceiver module complies with SFP MSA, IEEE 802.3z, and SFF-8472, so it is suitable for any MSA-compliant equipment. Instead of an OEM supplier, it comes from OPTCORE, a third-party manufacturer. Hence, this SFP offers a very affordable price compared to the original SFPGSX. Most importantly, we code and test each transceiver to ensure it works flawlessly with the Korenix 1G network switches, routers, servers, and network interface cards (NICs).1000Base-SX multi-mode transceiver 550m
