CABLE OPTICAL FIBRE 750 - EXTERNAL – ARMOURED - SINGLEMODE NON-PRESSURISED
This cable is specifically designed and constructed for direct, in the ground, burial installations. The cable is of loose tube construction containing 4 single mode colour coded fibres within a water blocked tube. A single tube plus dummy fillers as necessary are assembled helically in one layer around a non-metallic central strength member. 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 of these inner components is provided by a layer of helically applied galvanised steel wires. The cable 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 meet or exceed the requirements for 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 1909.
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.
