Vericom PC08U30218RAQ01M duplex fiber optic patch cords utilize Corning® Fiber Optic Glass for superior optical performance, and are constructed with 1.8mm duplex cable with 900um buffered fiber and aramid yarn to provide strain relief to the connectors. The cables ship in a standard A-B polarity but the polarity can be modified for data center applications that require a different polarity due to pre-terminated cassette design. Patch cords are UL OFNR for non-plenum applications. LC connectors have standard 1.25mm ferrule. These cables are built to meet TIA-568-C.3 with regards to patch cord performance and transmission requirements.
