HD-SDI Cable Assembly - Belden 7731A

Introduction

HD-SDI patch cables using BELDEN 7731A 6GHz cable and precision BNC plugs. These HD-SDI patch leads are assembled at our Harlow, Essex assembly facility under our proven quality control system.

Belden 7731A is a RG11 size low loss serial digital coax video cable (OD 10.16mm) suitable for long cable runs for both analogue and digital applications including live broadcast and pre and postproduction. Also suitable for older applications (composite, component & widescreen video).

Belden 7731A has a 14awg solid conductor, with foil and tinned copper braids and a Black PVC jacket, which is UV resistant and suitable for indoor and outdoor use.

Note: Belden 7731A patch leads are made to order and are normally available on a short lead time
