How to lay long-distance optical cable?

Long-distance trunk communication cable laying and easy way to buried plastic pipe laying based, individual lots can be used under field conditions overhead. Different way of laying shall meet the following requirements:

① method using buried fiber optic cable laying requirements as soil depth and ground conditions vary by building.

② buried fiber optic cable and other buildings and the minimum distance between the underground pipeline should meet the specification requirements.

③ cable laying or installation shall not be less than the minimum bend radius 20 times the cable diameter, bending radius after installation of fixed not less than 15 times the cable diameter.

④ the same number of cable trench laying the net distance between the parallel should not be less than 10 cm and shall not cross or overlap.

⑤ In the following cases may be part of the use of overhead:Through the ditch, and other buried valley building unsafe or expensive the lot; ground or underground obstructions are more difficult construction in particular the high cost of the lot or compensation; construction planning for the impact of other non-permanent location; have significant occurrence of subsidence or settlement lot; route if there is no permanent bridge built strong private or public access, but allow line support to do when hanging can be hung on the bridge shelves.The following sections should not be linked to the use of frame:Minimum temperature is below 30 ℃ areas; often subjected to strong storm or sandstorm hit the lot.

⑥ buried in long-distance optical cable lines into the city, town, should have been set in the new telecom or laying the pipe, you should consider the reasonableness of the location occupied by pores, and the cloth should be placed in plastic tubes in the child.

⑦ long-distance fiber optic cable can also be a dedicated long-distance fiber optic cable in the plastic pipe laying. Long-distance fiber optic cable length of plastic pipe should be large silicon core high-density polyethylene pipe (HDPE), to facilitate the use of gas delivery cable laying technology.Long-distance fiber optic plastic pipe construction should meet the specifications, plastic pipe and power line parallel to the minimum gauge, plastic pipes and other underground pipelines gauge, plastic pipes and other building facilities, gauge, plastic pipe buried depth in the relevant design specifications.
