High-performance CresFiber 8G SM is single-mode step-index fiber optic cable engineered by Crestron to support long-distance DigitalMedia cable runs in large buildings, campuses, and municipalities. When used with DigitalMedia8GSingle-Mode Fiber (DM 8G SMF) devices, CresFiber 8G SM guarantees consistent performance over cable runs up to 12 km (7.5 miles).[1] It is tested to wavelengths up to 1550 nm and meets the requirements of ITU-T G.652.D.
CresFiber 8G SM provides two individually jacketed fiber strands in a composite side-by-side "zip-cord" construction. This duplex configuration affords a complete DM 8G SMF solution with send and return channels in one cable. It is also ideal for individual DM 8G SMF wire runs where a spare backup fiber strand is desired. Zip-cord cable construction helps simplify termination, eliminating any need for a separate breakout assembly or intermediary splice.
CresFiber 8G SM is plenum-rated for use in an environmental air-handling space. It is sold in 2 km (6561 ft) spools. Meter markers are printed on the outer jacket making it easy to determine the exact length of each cable run when commissioning the installed system. Termination of CresFiber 8G SM cable can be accomplished using Crestron CRESFIBER8G-SM-CONN-LC-12 connectors and the CRESFIBER-TK termination kit.
