12G SDI Connectors for Cable Fixing Applications
12G Broadcast Cable Fixing
Ultra High Definition Video, also known as UHD or 4K requires an interconnect system that can transfer data at a frequency of 12Gbps. Using standard BNC connectors, this could require multiple channels.

As image resolution increases, so does the need for higher bandwidth connections.

The 12G-SDI (12 Gbps Signal/Data Serial Interface) standard as defined by the Society of Motion Picture and Television Engineers under SMPTE ST 2082, describes the electrical and physical characteristics of a 12G-SDI coaxial cable interface suitable for applications where the signal loss does not exceed an amount specified by the receiver manufacturer.

The above plot shows the performance of Gigatronix part number
BN15-1855-C06D-Z against the SMPTE specification with markers at various frequencies showing the significant headroom afforded by using a connector specifically designed to work at 12G/4K frequencies.

Gigatronix manufacture a range of 12G SDI compatible connectors including BNC, HD BNC (Micro BNC), DIN 1.0/2.3, MCX and TNC. All these connectors are optimised for 4K Ultra HD Broadcast, providing transmission on a single channel and are 12G-SDI, 4k Single Channel Compliant with excellent VSWR and Return Loss up to 12GHz.
