We offer one of the largest selections of Plenum fire rated 50/125 multimode fiber-optic cables for gigabit ethernet networking. 50 micron fiber is popular for longer runs between switches or data center racks. These cables offer an OFNP plenum rated jacketing, which is very popular running through air Plenum spaces and down walls without the use of conduit. Each cable features yellow bands with a number one or two to identify the send and receive leg of each multimode cable. Restock a large number of these cables in length from 1 m to 50 m in our California warehouse and we also offer 1 to 2 day rapid production of custom length fiber-optic cables for those who need a specific length.
