By Rajani Baburajan, TMCnet Contributor

Belden, a provider of cable, wireless signal, industrial networking and other transmission solutions, announced Belden Brilliance 1794A Precision Video Coax Cable, which the company claims as the first cable designed specifically to meet the requirements of emerging 1080p/50-60 3 Gigabit applications.

The company also announced expansion of its popular line of Brilliance Low Loss Precision Video Coax Cables, or "1694A," with a water-blocked version and a dual link version. 

Both cables are designed for use in serial digital interface or "SDI," HD-SDI and 1080p/50-60 applications, as well as analog video, according to company officials.

Steve Lampen, Belden's multimedia technology manager, said, "The new products reflect Belden's ongoing commitment to develop innovative products that help broadcast, video, and motion picture professionals stay ahead of the technology curve."

"End user customers - whether involved at the production or post-production end of the spectrum - know they can rely on Belden Brilliance cables for the top performance and rock-solid reliability they need to deliver news, information and entertainment," Lampen added.

Brilliance 1794A Precision Digital Video Cables feature the same high-velocity core as 1694A and have an enhanced Belden Duobond shield for the ultimate in shield effectiveness, the company said. 

With a slightly larger 14 AWG cable design, the product improves on the distance performance of 1694A at16AWG, providing 1080p/50-60 distance of 314 feet when calculated with the SMPTE distance formula, company officials said.

Brilliance 1694WB Precision Digital Video Cable is an ultra-rugged version of 1694A, which for many in the professional broadcast arena has become the industry standard for SDI video applications.

1694WB is designed for use in outdoor and direct burial applications. They feature a gel-filled, water blocking layer and hard black polyethylene jacket to provide effective weather resistance and protection against any ingress of moisture.

The cables' electrical characteristics are identical to those of 1694A, including the same attenuation and low return loss.  SMPTE distance and connector options also remain the same, according to company sources.

Brilliance 1694D Precision Digital Video Cable is a dual camera version of 1694A comprised of two 1694A coaxes within a single construction, the company said.  The dual cables are ideal for use in "dual link" 1080p/50-60 applications, as well as for all SDI, HD-SDI, 3D and 3D-HD applications.

Earlier this year, Belden announced its new FiberExpress Brilliance Field-Installable Connectors. Read the details here.
