The FDDI-rated N370-20M has 8.3/125 duplex (zipcord) fiber made from glass, instead of polymer. The sturdy LC male connectors meet stringent insertion loss standards and feature beveled edges on their glass ends for easy insertion into a patch panel or switch. The OFNR-rated PVC jacket is yellow to easily identify it as a singlemode cable.
