Kexint 24/48/72/96/144/288 Core Ribbon Optical Fiber Cable Duct Central Tube

Product Description

Product Description
Cable Description: Optical fiber ribbon are housed in loose tube.
Water blocking tape are used in and over the loose tube to prevent it from water ingress.
FRP is used as the strength member.
Polyethylene outer sheath is extruded around the tube.
