Patch cord

Fujikura provides the optical fiber Patch cord, Hybrid patch cord and Pigtail for laying in indoor installation and designed for telecommunication networks applications. The optical fiber is based on subcategory G.652.B and G.652.D in the ITU-T recommendation G.652 June 2005 and subcategory G.657.A in the ITU-T recommendation G.657 November 2006, and the optical fiber cable is based on the IEC 60794-3-10, March 2002.
