 Description

Optical Fiber Cable,GYTA33 The under-water optical cables DAYTAI manufactured are used in the shallow-water, andclimbing lay. The drainage optical cable is suitable for laying in the drainage optical cable is suitable for laying in the drainage duct. They not only have excellent mechanical property and humidity resistance, but have chemicalproperty and the function of rodent-proof and termite-proof as well. The structure of this optical cable is not complicated,  the low total cost provides every telecom operators a new solution.

 

 Application

Under-water optical cable is another structure which is different from undersea opticalcable. It is applicable for the installation in the seacoast and shallow water.It doesn’t need the junction, and can be used for the wiring under the waterwith shorter communication distance (for example: for is lands and the coastalcities).This cable is different from the environment of the undersea optical cable, it does n’t need plenty of fiber. Comparing to the undersea opticalcable, the under-water optical cable is simple structured, low cost, easyinstalled and transported. It is also easy to be repaired and maintained.


 Features

Itcontrols the extra length of the optical fiber precisely to ensure the goodperformance of stretch-proof and temperature characteristic of the opticalcable.

ThePBT loose tube material has good performance of hydrolyze-proof, the specialoily jelly is filled with the tube to protect the optical fiber.

ThePE sheath has excellent performance of radiation-proof of sun.

We take the steps as follow to ensure the waterproofness of the optical cable:

            1. The special water-proofcompound in the loose tube.

             2.Complete cable corefulfilled

             3.Plastic-plated aluminum belt moisture barrier

Themechanical and environmental character are in accord with YD/T 901-2001.
