What are the construction procedures for optical cables?
We can often hear news such as fiber optic cables being dug up. We can say that we are all too familiar with the term fiber optic cable. Then there may be many friends who don’t know much about fiber optic cables. Let’s talk about what fiber optic cables are and how to construct them. What are the programs.
Optical cable construction
What is fiber optic cable
Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications, it is a communication using one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups cable assembly. Optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic sheaths. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally have no recycling value.
Optical cable is a kind of communication line in which a certain number of optical fibers form a cable core according to a certain method, which is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That is: a cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of optical cable is generally composed of cable core, reinforcing steel wire, filler and sheath, etc. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.
What are the construction procedures for optical cables?
The construction procedures of general optical cable lines are mainly divided into five stages: preparation, laying, connection, testing and completion acceptance.
①Single-reel inspection of optical cable: Check the appearance of the optical cable, the relevant characteristics of the optical fiber and the signal line, etc.
②Route re-test: According to the construction design drawing, review the specific direction of the route, laying conditions, environmental conditions and the specific position of the joint, ground distance, distribution plate, distribution and so on.
③ Optical cable distribution: It is to calculate the total laying length according to the retest route and select the optical cable reel length reasonably.
④Route preparation: Pipe cleaning, pre-laying iron wires or pre-laying plastic conduits before laying optical cables, pre-laying steel wire ropes and hooks before overhead laying, excavation of optical cable trenches before direct burial laying, setting of joint pits, etc. It will facilitate the smooth progress of the project and the safe laying of optical cables.
⑤ Optical cable laying: According to the laying method, hang the single-disk optical cable rack on the pole or pull it into the pipeline, or put it into the optical cable trench.
⑥ Optical fiber cable connection installation: including optical fiber connection, copper wire, aluminum sheath, connection of strengthening core, and measurement of joint loss. The encapsulation of the joint sleeve and the support of the joint protection, etc.
⑦Relay measurement: including optical fiber characteristics (such as total attenuation of optical fiber, etc.) test and copper wire electrical performance test, etc.
⑧Completion acceptance of optical cables: Provide technical data such as construction drawings, revised routing diagrams and measurement data, and do a good job of on-site inspection and completion acceptance to provide qualified optical fiber lines and ensure system commissioning.
The above is all about what is an optical cable and what are the construction procedures of the optical cable. I believe that you have already seen some answers to what the optical cable is and the construction of the optical cable. I hope to give you some help.
