Fiber optic cable for microducting - 48F 4T12F, G652D, 5.8 mm
Extralink 48F 4T12F with 48 fibers type G.652D is a fiber optic cable designed for microduct applications. Fibers are placed in 4 tubes, apart from them there are 2 fillers inside the sheath. The tubes and fillers are twisted around the central reinforcement element, i.e. the FRP rod which constitutes the reinforcement element. The filler is Water Swellable Yarn, i.e. polyester yarn swelling in water, which prevents water penetration. The corrugated outer coating makes it easier to blow the cable into the sewer pipe.
6 tubes twisted around the central FRP rod - 4 loose tubes and 2 tubes as fillers
