Optic Fiber Cable Laying

Optic Fiber Cable Laying Solution

Qualfiber Technology's fiber optic cable widely applied in different kinds of environments. In order to adapt to the complex environment of various ways of optic fiber cable laying, we self-developed many base materials, such as aramid yarn, HDPE sheath material, water-proof material, etc. Every drum of fiber optic cables have been rigorously tested of mechanical strength, the inner structure, and intercommunity.

Conventional fiber optic cable of Qualfiber

1. According to the transmission performance, distance and use of different, cables can be divided into user cable,  local cable, long-distance cable, and submarine cable.

2. According to the different types of optical fiber used in optical cable, the optical cable can be divided into single-mode optical cable and multi-mode optical cable.

3. According to the number of optical fiber core in optical cable, the optical cable can be divided into single-core optical cable, double-core optical cable, and so on.

4. According to the different reinforcement configuration method, the cable can be divided into central strengthening member cable, dispersed strengthening member cable, sheath strengthening member cable and comprehensive outer sheath cable.

5 according to the transmission conductor, medium condition, the optical cable can be divided into no metal optical cable, ordinary optical cable, integrated optical cable (mainly used for railway special network communication lines).

6. According to the different laying methods, the optical cable can be divided into pipeline optical cable, directly buried optical cable, aerial optical cable, and underwater optical cable.

7. According to the different structures, the optical cable can be divided into flat structure optical cable, stranded optical cable, skeleton optical cable, armored optical cable, and high-density user optical cable.

Outdoor Optical Cable

Stranded Loose Tube Non-armored Cable (GYTA)

The fibers, 250pm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath.
