Optical Cables for Vertical Wiring in Buildings

Optical cables for vertical wiring in buildings, which is a major component of the drop segment in FTTx networks, refer to the drop cables going from ducts in buildings into rooms. Vertical wiring is mainly applied to high-storey buildings, super high-storey buildings, buildings with high-density subscribers and large information processing centers such as data centers. Features • Good flame-retard ant performance ensuring communication under fire conditions • Small size and light weight, allowing large transmission capacity in limited space • Good mechanical performance, including...

The duplex cable uses two 900|im or 600pm tight buffered fibres as optical transmission medium, covered with aramid yarns as the strength member, then a LSZH sheath is extruded. Other sheath materials are available on request. Features • Tight buffered fibres with excellent strippability • Good flame-retardant performance • Aramid yarns providing excellent tensile performance • Anti-corrosion, water blocking, flame-retardant and environment-friendly Applications • Fibre jumper or pigtail • Indoor riser level and vertical cabling • Interconnection between instruments and communication...

The duplex flat optical cable uses two 900pm or 600pm tight buffered fibres as optical transmission medium, covered with aramid yarns as the strength member. A PVC inner sheath is extruded on each fibres, then a flat PVC outer sheath is extruded. Other sheath materials are available on request. Features • Tight buffered fibres with excellent strippability • Good flame-retardant performance • Aramid yarns providing excellent tensile performance • Compact arrangement of fibres due to flat structure • Anti-corrosion, water blocking, flame-retardant and environment-friendly Applications •...

The multi-core bundle optical cable uses several 900pm or 600um tight buffered fibres as optical transmission medium, covered with aramid yarns as the strength member, then a PVC sheath is extruded. Other sheath materials are available on request. Features • Tight buffered fibres with excellent strippability • Good flame-retardant performance • Aramid yarns providing excellent tensile performance • Anti-corrosion, water blocking, flame-retardant and environment-friendly • All-dielectric design, applicable to lightning-prone areas Applications • Multi-core optical fibre flexible connector •...

The multi-core branch cable I uses several simplex optical cables (made of 900pm tight buffered fibre and aramid yarns) as optical sub-units. Sub-units are stranded around a non-metallic central strength member to form a cable core. Then a PVC sheath is extruded on the core. Other sheath materials are available on request. Features • High tensile strength due to stranded structure and non-metallic central strength member • Anti-corrosion, water blocking, flame-retardant and environment-friendly • All-dielectric design, applicable to lightning-prone areas • Connection between communication...
