Optical Cables for Networks in Rural Areas
9Pages

With the development of urban broadband and the improvement of rural economic level, the demands for broadband networks in rural areas are increasing. However, it is hard to realize the FTTH in rural areas because of the high construction costs and large regional differences etc. Based on the characteristics of cabling in rural areas, YOFC integrates different types of optical cable and ODN products and provides solutions for cabling in rural areas.

The optical networkin rural areas, which is non-urban network, is also consisted of the feeder segment, the distribution segment and the drop segment. Central office is connected to the...

YOFC provides optical cables for networks in rural areas, which have the following merits: • Optimized product design to meet the application requirements at optimal costs • Diverse optical cable products to meet different application requirements • Maximum utilization of existing pole and line resource • Easy construction and convenient operation Note: For selection of types of optical cables for the feeder and drop segments, it is suggested to refer to the conventional types for FTTH networks. For specific technical characteristics, please refer to technical specifications of YOFC. •...

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. Features • Good mechanical and temperature performances • All-dielectric design, applicable to lightning-prone areas • Aramid yarns ensuring tensile strength of optical cable • Small size and light weight, easy for installation • Different tensile strength can be designed on request for short-distance self-supporting aerial and duct installations 0 Fibre 0 Tube Filling...

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. Features • Good mechanical and temperature performances • All-dielectric design, applicable to lightning-prone areas • Small size and light weight, easy for installation • Glass fibre tape armor providing certain anti-rodent performance Technical Characteristics Type Note: 1. Xn refers to fibre type. For details, see naming rules for optical cables of YOFC. 2. For color arrangement of fibres,...

Tight buffered fibres are housed in slots in different numbers as needed. A phosphated steel wire is used as the central strength member. The slotted core is wrapped with water-blocking tape and a rip cord is placed outside the tape. Then the core is armored with laminated aluminum tape and a PE sheath is extruded. Features • All-dry design, improving efficiency of construction and splicing • Easy for branching of a single fibre • Good mechanical and temperature performances • Applicable to outdoor duct or aerial installations, and vertical installation O Rib Mark 0 Strength Member 0 Tight...

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 is extruded . Features • Accurate process control ensuring good mechanical and temperature performances • Unique flat shape providing excellent crush resistance, applicable to special wedge clamps for installation • Two FRP strength members in parallel close to the tube, easy for stripping •...

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-8 PE sheath is extruded. Features • Figure-8 design, easy for self-supporting aerial installation, reducing installation costs • Good mechanical and temperature performances • Small size, light weight and soft, easy for installation • Applicable to short distance self-supporting aerial installation...

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 wire is applied as the messenger. Finally, a figure-8 PE sheath is extruded. This type of cable is typically applicable to selfsupporting aerial installation. Features • Figure-8 design, easy for self-supporting aerial installation, reducing installation costs • Good mechanical and temperature...
