MSS Underground Loose Tube Fibre Optic Cables are available from MSS Fibre Systems . They are designed to be easily pulled into a tight duct. In addition, they can be aerially lashed or directly buried underground.
There are two types of MSS Underground Loose Tube Fibre Optic Cables:
- Loose Tube Multi Tube Fibre Optics Cable: Up to 72 optical fibres are contained in jelly filled loose tubes. The tubes and fillers are laid up around a central non-metallic strength member, “dry” blocked, taped, and polyethylene sheathed with nylon outer jacket.
- Loose Tube Mono Tube Fibre Optic Cable: Up to 24 optical fibres are contained in a single, jelly filled loose tube. They are strengthened with flexible non-metallic armour bonded to the inner polyethylene sheath, with an insect-resistant nylon outer jacket.
