Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling. The implementation of a cabling design, compatible with LED and laser-based Ethernet network devices, which will allow the integration. Yet I am seeing references on the Internet to 40km for 10Gbase-ER as well as stating that 1000base-LX supports 10km and some vendors even offer that up to 20km although it's not in the standard - implying that 10km is actually in the standard for the LX cable. Can anyone advise why the discrepancy. Alternate Name Transmission Speed OM1 (62. 5/125) OM2 (50/125) OM3 (50/125) OM4 (50/125) OS1 (9/125)Let's dig deeper into the numbers for full details of your fiber optic cable range: 1 GB/s Network – An OM1 cable supports 1000BASE-SX up to 275 meters, increasing to 550 meters with an OM2 cable. If you want to reach greater distances of 860 meters, it's probably best to use single mode cable. Many factors decide the fiber cable distance, but the key factors include the below six aspects.
