TRATOS FIBRE® CW1857

CABLE OPTICAL FIBRE 640 - EXTERNAL – ARMOURED - SINGLEMODE NON-PRESSURISED

Telecommunication Cables / Optical Fibres Cables / UK Telecom Fibre Optic Cables

These two cables are specifically designed and constructed for direct burial installations using a mole plough or other mechanical means. These cables are of loose tube construction containing 12 single mode colour coded fibres within each water blocked tube. Three or four colour coded tubes plus dummy fillers as necessary are assembled helically in one layer around a non-metallic central strength member, the design being specially chosen to ensure that the cable is neutrally balanced along its central axis. The interstices contain dry water blocking before the application of a water blocking binder tape and black polyethylene inner sheath, two rip cords are inserted under both the inner and outer sheath to aid stripping and termination of the cable. 

Mechanical protection is provided by a layer of longitudinally welded corrugated steel tape which also acts as a moisture barrier and rodent protection. This is then sheathed with a robust black high density polyethylene sheath which ensures outstanding pliability and protection.

The Step Index single-mode optical fibre (SMF) fibres used to manufacture these cables for BT meet or exceed the requirements for both Category 2 as specified in CW 1505 for systems operating in the wavelength range of 1250nm to 1625nm.

Tratos uses OFS and Prysmian fibres to manufacture the single mode Optical Fibre Cables supplied to BT.

These cables meet or exceed the requirements of CW 1857.

All of the polymeric materials used in the construction of cables for BT meet or exceed the requirements of BT Specification CW1500-7 and are RoSH compliant.
