GYTA333 fiber optic cable is the type of fiber optic cable used in shallow-water as well as climbing lay.  In other words, GYTA333 fiber optic cable is referred as an underwater cable since is used under water. In most cases, the GYTA333 fiber optic cable is laid in the water drainage and it has fantastic feature that enables it to perform effectively under water environments.  Additionally, GYTA333 fiber optic cable has a humidity resistance as well as excellent mechanical property that prevents it from breaking. Also, it is rodent-proof as well as termite-proof and that makes it adapt well to watery environment. 

It controls the extra length of the optical fiber precisely to ensure the good performance of stretch-proof and temperature characteristic of the optical cable.

The PBT loose tube material has good performance of hydrolyze-proof; the special oily jelly is filled with the tube to protect the optical fiber.

The PE 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 waterproof compound in the loose tube;

2. Complete cable core fulfilled;

3. Plastic-plated aluminum belt moisture barrier;

The mechanical and environmental characters are in accord with YD/T 901-2001.

Steel wire strength, filler protect tube fiber, steel tape armord.

Good ultra violet radiation resistant property. 

Double sheath. Good moisture-resistance.

Fiber count: 12-144 cores.

Underwater optical cable is another structure which is different from undersea optical cable. 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 water with shorter communication distance (for example: for islands and the coastal cities).This cable is different from the environment of the undersea optical cable, it does not need plenty of fiber. Comparing to the undersea optical cable, the under-water optical cable is simple structured, low-cost, easy installed and transported. It is also easy to be repaired and maintained.

Adopted to outdoor distribution.

Suitable for aerial duct and buried method.

Long distance and local area network communication.

GYTA333 fiber optic cable has upgraded many swampy or watery areas. This optical cable has made use of the areas that seemed to be impossible with water.  In reality, it has brought to life the already abandoned areas and that has brought significant change in our society today. People are now making use of the areas they had previously abandoned.
