Description

The AV:Link BNC coupler is a back-to-back barrel connector with BNC female sockets at both ends, designed to join two BNC male cables together when extending CCTV or video signal runs. The coupler maintains 50 ohm impedance throughout the connection, minimising signal loss and reflections in coaxial video systems.

Primarily used in CCTV installations where pre-terminated cables need to be joined or extended without re-terminating, the coupler also suits studio video patchbays, broadcast monitoring setups, and test equipment connections. The metal barrel provides a solid mechanical connection and RF shielding to prevent interference from entering the signal path.

The BNC bayonet connection locks with a quarter-turn twist, making connections fast and vibration-resistant compared to screw-thread alternatives. The coupler accepts standard BNC plugs from most cable manufacturers and maintains full compatibility with composite video, component video and RF signals carried on 50 ohm coaxial cable.

Frequently Asked

What signals does this coupler support?

The coupler is rated for composite video, component video and RF signals carried on 50 ohm coaxial cable. It is commonly used in CCTV systems running analogue video feeds between cameras and DVRs or monitors.

Does joining cables degrade the signal?

Every connection introduces a small impedance discontinuity and potential signal loss. In CCTV runs under 100m with good quality cable, a single coupler typically has negligible impact on video quality. For longer runs or broadcast-grade applications, consider using a single continuous cable where possible.

Is this compatible with 75 ohm BNC cables?

This coupler is specified as 50 ohm. While it will physically connect to 75 ohm BNC cables used in broadcast video, the impedance mismatch may cause reflections and signal degradation. For 75 ohm systems, use a coupler rated for 75 ohm impedance.

Can I use this to extend an antenna cable?

If the antenna cable uses BNC connectors and operates at 50 ohm impedance, yes. However, many domestic antenna cables use F-type connectors or different impedances, so check cable specifications before connecting.
