Belden 1855A is the smallest of Belden's standard range of Brilliance® precision video coaxial cables. It's the "little brother" of 1694A and 1505A, and is of the same design and construction, but in a smaller profile. Like its big brothers, it's sweep-tested to 4.5 GHz, so is suitable for anything from narrow-band applications like composite video through wide-bandwidth applications like SDI, every reel being 'swept' for return loss and certified.
This is designed to assure broadcasters, leading-edge broadcast equipment manufacturers and the standards bodies, of high performance and reliability as they migrate from the existing 1080i (interlaced) SDI format to the emerging 1080p (progressive) format, protocols and equipment, which require twice the bandwidth of 1080i.
