3G/6G/12G/HD-SDI Cable BNC to BNC Digital Video Cable (Belden 1694A) Belden 1694A Low Loss Serial Digital Coaxial Cable is an RG6 coax designed to carry several video signals including analog, 4x3 digital (SD-SDI), high definition (HD-SDI) and even 3gig (1080p/50 or 1080p/60). The center conductor is made from true 75 Ohm 18AWG solid copper. This cable is 100% sweep tested and is ready to meet today’s requirements of 6 Gbps data transfer.can be used in professional broadcast applications. Features and Specifications: Center conductor: 0.40" dia. bare copper Dielectric: 0.180" dia. foamed PE Shield: 100% aluminum foil/polyester tape/aluminum foil and 95% coverage tinned copper - give them maximum protection from EMI and RFI,for excellent noise rejection Nominal impedance: 75 ohms-ideal - for audio and video PVC outer jacket - for durability and long-term protection. Velocity of propagation: 82% Capacitance: 16.2 pF/ft. Nominal attenuation: 0.240 dB/100 ft. @ 1 MHz Overall diameter: 0.274". Serial Digital Data Rates Standard Definition SD-SDI (270 Mbps, ST 259) HD standard HD-SDI (1.483 Gbps, ST 292) 3G-SDI (2.97 Gbps, ST 424) 6G-SDI (5.94 Gbps, ST 2081) 12G-SDI (11.88 Gbps, ST 2082) Packing: 1pcs sdi extension cord + 1pcs a spool + 1pcs special bag NOTE: 50 Ohm BNC connectors are used with 50 Ohm cables. 75 Ohm connectors are used with 75 Ohm cables. 50-ohm cables/connectors work well with old analog video formats. If you are looking for high-quality video output, 50 Ohm will not give you a high-quality level. We are a professional manufacturer. If you need other length Cable, please contact us by email.
