CABLE OPTICAL FIBRE 730 - SINGLEMODE
This cable is specially designed and manufactured for installation into underground ducts by the use of direct pulling techniques with a rope or glass rod.
This COF 730 cable contains 432 single mode fibres within a non-pressurised black polyethylene sheath. Twelve colour coded fibres are contained within each water blocked tube.36 such colour coded tubes 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 individual fibre and tube colour identification scheme used is in accordance with CW 1910
The interstices contain dry water blocking before the application of a water blocking binder tape and black high density polyethylene sheath, two rip cords are inserted, diametrically opposite, under the sheath to aid stripping and termination of the cable. The robust polyethylene sheath used by Tratos meets or exceeds the requirements of BS EN 50290-2-24 and ensures outstanding pliability and protection.
Tratos has developed this cable to have the optimum balance of properties, toughness to pulling into ducts combined with a smooth, low coefficient of friction, surface, to ease installation and prevent jamming.
The Step Index single-mode optical fibre (SMF) fibres used to manufacture these cables for BT met or exceed the requirements for Category 2 as specified in CW 1505 for systems operating in the wavelength range of 1260nm 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 1910.
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.
