At the 2017 NAB Show, Canare showcase its new 12G coax solution for economical transport of 4K UHD television signals.
Canare said 4K UHD is fast becoming the dominant industry standard for sports, live events and commercial production work, placing increasing demands on teleproduction companies and truck operators to provide a 4K product.
For that reason, the company introduced a new line of coaxial cable and connectors that are specially optimized for 12 Gbps. It is now feasible and convenient to transport 4K signals at distances up to 328-feet via copper.
Canare’s L-5.5 CUHD coax cable has enhanced attenuation characteristics that allow transport of 12G signals at greater distances than comparable-sized coax currently available. It is also ideal for high-performance transport of 3G and 6G video, allowing system designers and integrators to future proof construction of new teleproduction facilities.
“Many industry professionals feel that the most practical way for handling 4K is via coax, with the SMPTE organization having issued a coax-based standard for 12G transport, SMPTE ST 2082-1:2015,” said Shadath Shahid, engineering manager at Canare. “We have responded by creating a new line of 75-ohm coaxial cable and BNC connectors that are specially optimized for 12G performance.”
Canare’s L-5.5 CUHD coax features the same outer diameter and ease in handling and installation as the company’s previous L-5CFB HD/3G cable, but with enhanced attenuation characteristics that allow transport of 12G signals at much greater distances than L-5CFB.
Canare’s new 12 GHz-rated 75-ohm series of BNC cable and PC board-mounted connectors round out the 4K copper transport equation, as they have been specially optimized for both enhanced high frequency performance and return loss characteristics.
The new “D” BNC cable connectors feature a return loss of 15 dB at 12 GHz, and the board-mount connectors offer a return loss of 10dB at 12 GHz.
Both cable and circuit board connectors are engineered for a precision fit and high mechanical stability, and board-mounted devices are gold plated to ensure solder-ability and a low-impedance connection.
