Bryant Unlimited HD transmission solutions.

To handle HDTV, broadcasters are faced with investing a considerable amount of money in new equipment, such as cameras, remote broadcast units, control rooms, cables, new titling and editing equipment, new tape machines, new rigs for their new OB vans — its a big investment and one that needs to be right first time.

For HDTV cables a bandwidth of 750MHz and data rate of 1.5Gbps is necessary with good Return Loss performance at the third harmonic frequency of 2.25 GHz (3 x 750). SMPTE 292E details a bandwidth of 2.4 GHz. Insertion losses at HDTV frequencies are much greater than with SDI at 270 Mbps and need to be kept well below 20dB. Bryant BD SD11 and Belden 1694A coaxes intended for HDTV applications are currently tested up to 3 GHz and have a typical RL of 30dB. The 'headroom' built in to these cables allows up to 6dB below the recommended 20dB.

Bryant hybrid HD optical camera cables using LEMO Connectors meet all the criteria of the SMPTE 311M specification for use with high-end cameras from such manufacturers as SONY.

Bryant Unlimited MUSA jackfields (as utilised in the BBC's massive new HD OB unit 12) have been independently tested to an unbeatable 5GHz to cover integrity of signals up to and including the 7th harmonic ~ way beyond current SMPTE requirements.

Bryant coaxial connectors, patch cables and MUSA or BNC patch bays are as close to 'true' resistive 75 Ohm as is technically possible to prevent impedance mismatching and signal reflections.

The Switchcraft VPP Video Patchbay with 24 or 26 self-normalling (switching) jacks is rated from DC to 3.0 GHz and meets SMPTE 292M specifications.

The Switchcraft MVP mid-size series offers 32 self-normalling (switching) jacks, rated at 30,000 lifecycles in either 1U or 2U, complete with cable tie bars. As with the VPP range, jacks may be terminated or non-terminated to suit. The rear BNC part of the switching jacks are staggered by row to make installation of BNC cabling much simpler in the confined space of 1U.

Belden/CDT's New RG-179 Type coaxial cable is ideal for HDTV broadcast trucks — weighing about 60% less and taking up to 40% less space than standard Mini RG-59/U Type coaxes. Belden's new 179DT coax was designed for use in analog, SDI, HD video and AES/EBU digital audio transmissions. Brilliance® DigiTruck® 179DT Coax has a guaranteed return loss of 21dB (minimum) and is sweep tested to 3 GHz. This mimics the return loss performance of Belden's most popular Brilliance® precision video cables, providing 6dB of RL headroom against the SMPTE 292M specification. 179DT features a highly crush-resistant, foamed high-density polyethylene (FHDPE) dielectric to help ensure the durability of the cable — a particularly important characteristic for use on outside broadcast trucks — and a foil/braid shield consists of a unique lightly bonded Duobond® tape, that can either be left bonded to the insulation to simplify termination with one-piece connectors, or removed for use with multi-piece designs.

The latest addition to Bryant's Fibre Optic armoury is their unique new partnership with ZeroPsi to provide onsite support for fibre optic infrastructure.

The Mobile Fibre Laboratory is a purpose built utility vehicle that provides a controlled environment together with state of the art production, test and repair equipment to enable fibre optic termination, installation and repair on-site or in the field. Supported Broadcast connectors include Lemo SMPTE 311M HDTV, Neutrik opticalCON Duo/Quad and some expanded beam.

The mobile fibre laboratory can operate independently using its own on board power unit allowing its use in remote locations. Portable termination facilities and fusion splicing are also available to provide support for fixed infrastructure installation and repairs.
