Tight buffered fibres are surrounded with a layer of aramid yarns as the strength member. A LSZH inner sheath is extruded on the tight buffered fibre to form an optical sub-unit. Then optical sub-units and fillers are stranded into a cable core. Finally, a LSZH sheath is extruded outside the core. The fillers can be made of other high-strength yarns and other sheath materials are available on request.

Distribution Tight Buffer Optical Cable use 900μm or 600μm flame-retardant tight buffer fiber as optical communication medium. The tight buffer fiber wrapped with a layer of aramid yarn as strength member, then completed with a layer of PVC or LSZH material as out jacket.

Indoor cable Φ900μm or Φ600μm tight buffer , spiral steel armor, layer of Kevlar yarn, LSZH/ PVC/ OFNR Jacket.

Indoor cable. 1 fiber, Φ900μm or Φ600μm tight buffer , spiral steel armor, layer of Kevlar yarn, LSZH/ PVC/ OFNR Jacket.

Round Self-supporting Cable use 900um flame-retardant tight buffer fiber as optical communication medium. The tight buffer fiber wrapped with a layer of yarn as strength member units, Then the wire rope is integrated into an 8-shaped LSZH sheath cable
