CQR Cat5e Cable, UTP Grey PVC, Eca, 305m CAT5eUTP/GY/PVC/305

Overview

A Cat5e cable carries network data along twisted copper pairs. Twisting each pair helps it reject interference from the pairs beside it.

This one is bulk cable, not a finished lead. You cut it to length and fit your own plugs or outlets at each end.

Where to use it

This cable has a PVC sheath. PVC is a common choice for indoor runs through walls, ceilings and containment.

Confirm the route with the job specification, especially where cable passes through escape routes.

What the figures mean in practice

• 90 metres: this is the longest run CQR gives. Plan the route before pulling cable, because bends and detours add to the measured length.
• 305 metres: divide this by your typical run to see how many runs one length will give, and allow for waste at each end.
• CSA: cross-sectional area, the size of the copper in each core. A smaller area means more voltage drop if power is sent along the cable.
• HDPE insulation: high density polyethylene, the plastic around each core.

Installing it

• Stripping: use the rip cord to open the sheath, then trim it back without nicking the core insulation.
• Solid core: solid conductors suit fixed wiring and do not like repeated flexing. Use stranded patch leads for the last connection to equipment.
• Testing: test every finished run with a cable tester before closing up the route.

Planning your system

The cable is only part of the job. You will also need RJ45 connectors or outlets, a crimp tool, and usually patch panels at the equipment end. Check each one states that it suits solid Cat5e.

Standards and ratings explained

• ISO 11801: the international standard for general building cabling.
• EN50575: the European product standard for how cables in buildings react to fire.
• Euro Class Eca: the classes run from Aca down to Fca, and Eca sits near the bottom of that scale. It has nothing to do with speed or data quality.
