Multimode fiber patch cables in this length range are typically used in data centers or enterprise environments where you need to connect switches, servers, or storage equipment across longer runs than standard patch cables allow. The OM4 spec supports 40G and 100G transmission, so it's a practical pick if your hardware requires higher-bandwidth connections. Buy Now at Newegg

Useful if you're working with 10GbE or 40GbE network runs that require OM4 multimode fiber, particularly in data center or enterprise environments where the MTRJ connector format is already in use on your equipment. Buy Now at Newegg

A practical pick for connecting network equipment over longer runs within a building, particularly if your switches, servers, or storage devices use LC ports and require multimode fiber. At 200 meters, this cable suits larger facilities where copper cabling falls short. Buy Now at Newegg
