4 Kinds of Fiber Optic Cables Introduction

Communication cable since 70s application, has now developed into a long haul, local telephone relay, underwater and undersea communications and local area networks, private networks and other cable transmission backbone, and has begun to develop the access network to the user by the fiber to curb (FTTC), fiber to the building (FTTB) and so on to the fiber to the home (FTTH) development. For a variety of applications and environmental conditions, communications cable with aerial, buried fiber optic cable, pipelines, underwater, indoor installation, etc.

FTTH Drop Cable

Aerial optical cable

Aerial cable is hung on pole using optical fiber cable. This way of laying can take advantage of the existing aerial light road, save construction costs and shorten the construction period. 

Aerial cables hanging in the pole, must adapt to a variety of natural environments. Aerial cables susceptible to typhoons, ice, floods and other natural disasters, the threat also vulnerable to outside influence and weaken their mechanical strength and other effects, so the failure rate is higher than the aerial cable and pipeline buried fiber optic cable. Generally used for long-distance two or level 2 of the line, cable lines for private networks or some local special location.

Direct Burial Fiber Cable

The cable outside a strip or wire armored, direct burial in the ground, requiring performance against external mechanical damage and prevent soil erosion performance. According to the different use of the environment and conditions for use of different sheath structure, for example, there are areas of Pest Insects and Rodents, to use a pest control rat gnawing of the cable sheath. According to the soil and the environment, the depth of buried fiber optic cable is generally between 0.8m to 1.2m. In laying, you must also pay attention to maintaining fiber strain within the limits allowed.

Duct Optical Cable

Pipe laying is usually in urban areas, pipe laying environment better, so the cable sheath are no special requirements, no armor. Pipe laying before the next election and the length of the segment connecting point. Laying beside cited can use mechanical or manual traction. Do not exceed a towing cable to allow traction tension. Pipe materials can be produced based on the geographical choice of concrete, asbestos cement, steel, plastic tubes.

Underwater Fiber Optic Cable

Underwater fiber optic cable must be used wire or steel armored structure, retaining layer structure according to the hydrogeological conditions of rivers into account. For example, in stony soil, erosion and strong seasonal riverbed, cable suffer from wear and tear, Rally situation, do not only need thick steel wire armored, to use its double-armored construction methods should be based on river width, water depth, flow rate, etc. for the selected drawing riverbed.

Laying underwater fiber optic cable buried fiber optic cable severe conditions than many, techniques and measures to repair the failure is also much more difficult, so the reliability requirements of underwater fiber optic cable buried fiber optic cable than high.

Submarine cable is underwater cable, but the laying of underwater cables environmental conditions more severe than normal, demanding the submarine cable system and its original life requirements in more than 25 years.
