Loose Tube Fiber Optic Cable Is Used

But each is designed for very different environments.

Loose tube fiber optic cable is used. Loose tube fiber and tight buffered fiber. Loose tube and tight buffered. Fiber optic cable is available in many physical variations such as single and multiple conductor constructions aerial and direct burial styles plenum and riser cables etc. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed.

Fiber optic cables are constructed in two ways. This type of cable protects the fiber from stresses caused by the environment namely moisture and temperature. From the picture below we can see that loose tube fiber holds more than one optical fiber each individually. Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves.

Loose tube and tight buffered. There are two styles of fiber optic cable construction. Both contain some type of strengthening member such as aramid yarn stainless steel wire strands or even gel filled sleeves. But there are two basic styles of fiber optic cable construction.

A fiber optic cable also known as an optical fiber cable is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288.
