Duplex Jumper LC-LC 50/125µ, OM5, LSZH, lime green, 2.0mm, 30m. Fiber optic patch cables are defined components of an internationally standardized structured cabling system according to ISO/IEC 11801. Historically, various connectors have evolved in structured cabling, with the following still being relevant: LC, SC, E2000, MPO/MTPE. A fiber optic patch cable represents the shortest connection between a passive cabling port and an active network port or a point-to-point connection between two active network ports. Quality classes allow for a qualitative distinction of fiber optic patch cables depending on the network service. Equivalent terms for patch cables include: patch cord, adapter cable, connection cable, hybrid cable, jumper, and connection cord. Features of EFB fiber optic patch cables: strain relief reinforced with aramid yarn, halogen-free and flame-retardant jacket according to IEC-60754-2, IEC-60332-1, and IEC-61034. EFB fiber optic connectors meet the minimum quality class Grade B/2 according to IEC-6175.
