Buying Guide

Choose the correct pair count

Match cable pair count (e.g., 25-pair) to the number of extensions or trunks your PBX requires to avoid over- or under-provisioning

Prefer solid copper 24AWG conductors

Solid 24AWG copper offers lower attenuation and reliable IDC termination for voice runs compared with stranded alternatives

Select the right connector style

Decide between open-end telco cable and pre-terminated 50-pin IDC/RDC connectors depending on whether you terminate at punchdown blocks or plug into a 50-pin header

Verify fire-rating for installation location

Use riser (CMR) or plenum-rated cable per building code for vertical shafts and plenum spaces to meet safety requirements

Balance cable length and signal needs

Keep runs within recommended lengths for Cat3/24AWG voice circuits to maintain call quality; shorter runs reduce crosstalk and attenuation
