SDI Cable: Precision and Complexity

Coaxial cable might seem simple, but when it comes to delivering high bandwidth, manufacturing a consistent, high-quality cable becomes challenging. This is because every transmission line has a characteristic impedance requirement, usually 75 ohms for video cables. The impedance is influenced by the cable's physical geometry and materials, particularly the dielectric layer that insulates the center conductor from the shield. Achieving the desired impedance involves balancing inductive and capacitive reactance through the cable's inductance and capacitance.

Unfortunately, it's not as straightforward as measuring the cable's massed values of inductance and capacitance. Signal propagation over time and variations in impedance along the cable can cause signal reflections, known as "return loss," that interfere with the intended signal. To minimize these reflections, a cable needs consistency in dimensions and materials. Even microscopic variations or manufacturing imperfections can result in return loss.

Belden, with its expertise in precision coaxial cables, understood these challenges when SDI technology emerged. They applied engineering and manufacturing resources to produce precise video cables like 1694A. Unlike inexpensive cables, these precision cables undergo rigorous processes to maintain dimensional consistency and material quality. Everything from tension control during braiding to extrusion monitoring ensures the final product meets the highest standards.

Blue Jeans Cable: Crafting Cables with Excellence

At Blue Jeans Cable, we understand the intricacies of cable assembly, and assembling SDI cables requires precision. Our cables are stripped using Swiss-made coaxial cable strippers programmed for each cable's specific dimensions. This produces a clean and dimensionally consistent strip that fits perfectly every time.

To ensure quality crimps, we use pneumatic presses instead of hand crimping. These presses apply a straight vertical action with three tons of force, guaranteeing symmetrical and properly done crimps.

With attention to every detail, including conductor and shield lengths, powerful crimping force, and experienced technicians overseeing the assembly process, our finished cables meet the highest assembly quality standards consistently.

Decades of Expertise in Precision Cable Assembly

Blue Jeans Cable has excelled in the cable assembly business since 2002. Our manufacturing operation in Seattle, Washington, employs around a dozen skilled individuals dedicated to producing high-quality cables. We prioritize local assembly and continuously improve our materials, methods, and processes. Our goal is to offer consistent, superior-quality products. This requires experienced workers, and we are proud to employ technicians with a minimum of ten years of experience. We believe in the resilience of American manufacturing and appreciate our customers' support in making it possible.

In conclusion, Belden 1694A SDI Cable is specifically manufactured to meet the demanding requirements of 3G/6G and HD SDI. With its excellent shielding performance, sweep-tested cable stock, and solid copper conductor, it ensures reliable and high-performance video transmission. Trust Blue Jeans Cable for superior quality and decades of experience in precision cable assembly.
