Tratos® CW1842 – UK Telecom

CABLE OPTICAL FIBRE 215 ULTRA-LIGHT WEIGHT OVERHEAD FIBRE CABLE

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

This specification details the requirements for a range of light weight drop cables (COF215) for installation in the BT Fibre Network in Overhead and Underground environments.  Tratos® CW1842 BT cables are of multi element construction containing 4, 12, 36 and 48 single mode fibres. The 4 fibre cable is made up of one buffered tube, the 12, 36 and 38 fibre cables are manufactured in separate buffered tubes containing 12 colour coded fibres. The required number of tubes plus dummy fillers where required are assembled together helically with water blocking filling in the interstices. The fibre assembly is covered with a Black HDPE sheath containing two metallic strength members placed diametrically opposite each other. Each strength member comprises 3 x 0.32 mm diameter brass coated, steel wires. The robust abrasion resistant HDPE sheath used by Tratos ensures outstanding pliability and protection. Two ripcords are inserted under the sheath to aid stripping and terminating of the cable.

The single mode fibres used by Tratos to manufacture these cables meet or exceed the requirements of Category 2 fibres as defined in BT Specification CW 1505. The transmission application for these cables are for systems operating in the wavelength range of 1260nm to 1625nm

Tratos useS Lucent OFS and Prysmian fibres to manufacture the Optical Fibre Cables supplied to BT.

Tratos CW1842 ultra-light weight COF 215 cables are specially designed for overhead use and meet or exceed the requirements of CW1842, they are fully compatible with Standard BT drop wiring practice. Although primarily intended for overhead use these cables can also be used in underground installations where the smooth, low coefficient of friction surface of the sheath, eases blowing or drawing in ducts and prevents jamming.

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.
