Belden 1694F is an extremely flexible version of Belden's popular industry standard, 1694A. Like 1694A, this RG-6/U Type Low Loss Serial Digital coaxial cable provides top quality signal transmissions (both analog and digital). It also offers the user the benefit of superior cable life-whether it's used indoors or out-of-doors. And unlike other manufacturers' cables, 1694F provides the end-user and the installer with some unique cost and labor-saving benefits since it accommodates the same connector as 1694A, and therefore the same type of tool, throughout its installation-even at the patch panel.
Exceptional Flexibility and Flex Life
Belden Brilliance 1694F's flexibility makes this CM-listed cable easy to route through building walls and conduit in studio settings and other fixed installations. But 1694F's exceptional physical and electrical characteristics really make this cable ideal for use in patch bays, mobile studio trucks, remote outdoor field locations, and more. Today's on-the-move broadcast crews routinely subject the cables they use to repeated pulling, flexing, bending and crushing situations. Under these circumstances a conventional cable might develop discontinuities that could lead to degraded signal transmission-or the cable could even break. But Belden 1694F offers outstanding flexibility and long-life characteristics and an abrasion-resistant PVC jacket-in conjunction with superior electrical performance. In addition, digital audio signals increasingly run through coax in accordance with Audio Engineering Society standard AES-3id. Belden 1694F is an excellent choice for AES-3id applications where optimum flexibility and flex life are required. To ensure best-in-class Return Loss performance, Belden 1694F SDI/HDTV cable is 100% sweep tested to 4.5 GHz.Belden is the only cable manufacturer that has extended its testing to 4.5 GHz, assuring broadcasters and leading-edge broadcast equipment manufacturers of high performance and reliability as they begin to migrate from the existing 1080i (interlaced) HD format to the emerging 1080p (progressive) format, protocols and equipment which require twice the bandwidth of 1080i.
Construction
Optimum flexibility starts with a 19 AWG bare copper (compacted), stranded center conductor. Advanced impedance stability and Return Loss characteristics are achieved by the use of foam polyethylene insulation and state-of-the-art manufacturing processes.
The cable's shielding consists of a double tinned copper braid. This shielding construction provides superior flex characteristics over foil/braid shield designs, while offering 100 dB of shield isolation.An abrasion-resistant matte PVC jacket adds further protection and flexibility.
