Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with water blocking yarns. The tubes (and fillers) are stranded around the central strength member to form a cable core. The core is covered by water blocking tape and armored with aramid yarns. Finally, a PE(o...

Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member to form a cable core. The core is armored with a layer of fire resistance tape and glass fibre yarn...

Optical fibres are housed in 3 loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes are stranded around the central strength member to form a cable core. The core is surrounded with water blocking yarns and armored with laminated aluminum tape. A steel w...

Optical fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. The tube is surrounded with dry water blocking materials and armored with aramid yarns. A single steel wire or stranded steel wires are applied as the messenger. Finally, a figure-...

Optical fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. Two glass fibre reinforced plastic (FRP) rods are placed outside the tube in parallel, and water-blocking yarns is placed between the tube and the rods, then a flat-shape PE sheath i...

Optical fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. The tube is armored with a layer of glass fibre tape. Then a PE sheath is extruded.

Optical fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube fulling compound. The tube is armored with a layer of aramid yarns as the strength member. Then a LSZH sheath is extruded.

Tight buffered fibres are surrounded with a helical steel hose and a layer of aramid yarns as the strength member, and then a LSZH sheath is extruded to form an optical sub-unit. Optical sub-units and copper wires are stranded around a non-metallic central strength member to form a cable core. The...

Optical fibres are surrounded with a layer of aramid yarns as the strength member. Then a LSZH sheath is extruded and another layer of aramid yarns is placed outside the inner sheath. Finally a LSZH outer sheath is extruded. The strength members can be made of other high-strength yarns and other she...

Tight buffered fibres are surrounded with a layer of aramid yarns as the strength member. Then a LSZH sheath is extruded. The strength member can be made of other high-strength yarns and other sheath materials are available on request.
