Fibre providing the pipeline for broadcast transmission

Whether in-facility or in live production environments, fibre has replaced copper as the connectivity matrix for multiple broadcast applications

Many of the connection speeds required today are no longer feasible on copper, making fibre the cabling of the future, declares Cameron O’Neill, director, APAC, Riedel Communications.

Fibre, he tells APB, will also play a key role for IP in live production, which has been given a major shot in the arm with the ratification of many of the standards within SMPTE ST-2110. “To me, the older SMPTE ST2022-6 was basically ‘SDI by another name’ — same payload, but transported over Ethernet instead of coax cable,” O’Neill continues. “But 2110 is different; video, audio and data are all separated but synchronised on a single network. It means you are no longer sending unseeded audio to your vision switcher or video to your audio console.”

This, he explains, can significantly lower the amount of bandwidth that is required in some applications. “Even a ‘12G’ 4K/Ultra HD (UHD) stream takes less bandwidth than 10G when it’s only handling video signals.”

And O’Neill is convinced that Riedel continues to be at the forefront of being able to maximise the use of fibre for live productions, for both broadcasts and live events. The company, he reminds, has always been a fibre-based company, long before IP was even a discussion topic. “The Artist Fibre Ring for intercom was around even before Dante was ever being tested. Riedel’s MediorNet brought network topologies and distributed routing over fibre to the market in 2009.”
