Fibre optic patch cables are defined components of an internationally standardised structured cabling of ISO/IEC11801. Historically, many different connectors have grown in structured cabling, whereby the following are still relevant: LC, SC, E2000®, MPO/MTP. A fibre optic patch cable represents the shortest connection between a passive cabling port and an active network port or a point-to-point connection of two active network ports. Quality classes allow a qualitative differentiation of the fibre optic patch cables depending on the network service.
