General Description
The ST UPC to ST UPC fiber optic patch cord consists of a fiber optic patch cable that is terminated with ST UPC fiber optic connector on both ends. As the ST fiber optic connectors end faces come with the ultra-physical contact (UPC) finish, the attenuation loss during the optical connection is minimized. The ST to ST patch cord is available in various lengths, type of fiber and can be simplex or duplex to cater to the different network connection needs.
