10 Gigabit Performance for Critical Connections These fibre cords are OM3 rated for the extreme demands of SAN networks. The OFNP (plenum) rating conforms to strict NEC building safety codes but is compatible with unrated or OFNR (riser) rated applications. They are precision factory tested for insertion and return loss to ensure transmission performance per TIA-568-C.3 specifications. The combination of LC connectors in a protective yoke, strain relief boots and zirconia ceramic ferrules provides a dependable, low-loss performance. Bend Insensitive Engineering Bend insensitive multimode fibre (BIMMF) provides greater flexibility in tight spaces or long cable runs with multiple bends. BIMMF fibre cable is engineered with an extra layer of glass around the core to ensure optical performance and provide durability for the extreme requirements of SAN network or high density patch panel installations. It offers interoperability and backwards compatibility with OM3 and OM4 50 micron fibre systems. Protect your network against macro-bend losses that are difficult to isolate, troubleshoot, and repair.
