Product Description
|
| This product description is for Triple Jacket Double Armored Optical Fiber Cable designed to meet the Technical Requirements as mentioned as per specification documents, it fulfills the design for the applications desired therein. The design is based on stranded loose tube which provides stable performance over a wide temperature range and is compatible with any telecommunications-grade optical fiber. This Cable is suitable for both Duct and Direct Buried applications, it provides extra strength and rodent protection by using Double Armor and Two Inner Jackets. The stranded loose tubes contain thixotropic jelly for protection of the optical fibers as required. The Thixotropic Jelly protects the fibers within the loose tubes and provides excellent quality filling compound for stopping ingress/transport of water into the cable. The product is manufactured on ITU-T G.652.D fiber. It facilitates easy and economical installation. |
