xDSL twisted pairs or quads indoor cables

Nexans Expertise

The Nexans expertise is an overall management of the industrial process to guarantee performance level in the frame of the described application , especially in terms of :

- performance in terms of low crosstalk based on the design and manufacturing process.
- performances in terms of attenuation based on an optimum compromise between dimensions and electrical performance.
- performances in terms of screening effectiveness based on the high balance of the pairs and the use of optimized screen designs (bundle and/or cable screening with screening foil and or braid.
- performance in terms of ease of connector mounting based on the use of polyolefin insulation allowing wrapping and IDC and a bundle design adapted to the modularity of the DSLAM.
- performance in terms of flexibility based on the design and material choice
- flame retardant and low or non corrosive based on the appropriate choice of jacketing materials

The technology

1. Solid bare copper
2. pair of polyolefin insulated wires. The set of different pair twists guarantee low crosstalk. The polyolefin insulation guarantees wrapping and IDC.
3. plastic tape to separate the wires from the screen
4. bundle screen avoiding interferences between the different bundles and guaranteeing good EMC performances
5. drain wires for easy connection of the screening foils
6. overall screen guaranteeing good EMC performances
7. ripcord facilitating the removal of the sheath when connecting to the wiring block
8. sheath guaranteeing flame retardance, low smoke and low corrosivity
