One of The Latest Developments in Fiber Optic Cable Networking. The SM Duplex Patch Cord is a high-performance fiber optic cable that is designed to connect networking devices in data centers, telecommunications and enterprise applications. The cable has a duplex configuration - two fibres not more than a few tenths apart from each other - which means that when this pair is used for transmitting data over long distances with minimal signal loss (such as 100 meters of category 3 shielded twisted pair cable or 470 kilometers of optical fiber), one carries an electric signal for input as well as another working at 1310nm wavelength to work upon any light. Major functions involve the distant transmission of data with minimal signal loss and high-speed. Principal technological features involve a Corning or similar high-grade glass fibre core for internal optics, the LSZH jacket which provides flame resistance and one piece of precision polished connector ensuring optimal alignment and signal integrity throughout our products. Applications include : Server Connectivity, Switching, Fiber-to-the-Desktop installations
