TRATOS FIBRE® CW1852
CABLE OPTICAL FIBRE 260 – BLOWN - EXTERNAL - SINGLEMODE NON-PRESSURISED
This range of fibre cables is specifically designed for installation into sub-duct by the use of air blown techniques including “overblowing” although in some circumstances the cables are suitable for installation over short distances by the use of direct pulling techniques with a rope or glass fibre pulling rod. These cables are of loose tube construction each containing 12 step index single mode fibres used to make the 72 to 144 single mode fibres cables. The units of 12 fibres are colour coded within each water blocked tube, the loose tubes themselves are colour coded for identification. The required number of tubes plus dummy fillers where required are assembled helically 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 non-pressurised high density black polyethylene sheath, two rip cords are inserted under the sheath to aid stripping and termination of the cable. The robust high density polyethylene sheath used by Tratos ensures outstanding pliability and protection.
Tratos has developed this cable to have the optimum balance of properties, toughness to withstand blowing or pulling into sub-ducts combined with flexibility within a smooth, low coefficient of friction, surface, to ease installation and prevent jamming.
The Step Index single-mode optical fibre (9/125µm SMF) fibres used to manufacture these cables for BT meet or exceed the requirements for Category 3 as specified in CW 1505 for systems operating in the wavelength range of 1260nm to 1625nm.
Tratos use Lucent OFS and Prysmian fibres to manufacture the Optical Fibre Cables supplied to BT.
These cables meet or exceed the requirements of CW 1852,
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
