Primary coated Single Mode Fibre, filled, loose tubes, assembled around the Central Strength Member (CSM), filled core, metallic Moisture Barrier, Polyethylene sheathed optical fibre telecommunication cables, complying with National and International Standard Specifications.

Loose tube type cables are designed to provide highly reliable transmission quality and an excellent environment required for high class fibre performance.

These loose tubes are so designed to keep the fibres free from external mechanical forces present on the cable with the help of thixotropic jelly inside and having enough inside diameter of the loose tube for free movement of fibre. Each cable is designed for continuous operation even in severe environmental conditions and can be manufactured from 2F to 288F cables. These loose tubes are SZ stranded around a central strength member (CSM). Commonly used is FRP (Fibre Reinforced Plastic, but Steel can be used if required. This type of loose tube design is used for all types of outdoor fibre optic cables.
