Van Damme UHD Vision 12G SDI Cable — 268875006
The Van Damme UHD Vision 268875006 is a 75 ohm enhanced performance 12G SDI cable built around the industry-standard RG6/U coaxial format, engineered specifically for 4K single-link UHD video transmission in broadcast, live production, and permanent AV installation environments. Precision construction is the defining characteristic of this cable — every element of the 268875006 is optimised to ensure reliable, error-free signal integrity across the full range of modern video formats, from legacy SDI and HD-SDI through to the demanding requirements of SMPTE ST 2082 12G-SDI single-link UHD transmission.
As broadcast infrastructure transitions to 4K and UHD workflows, cable selection becomes a mission-critical decision. A coaxial cable that performs adequately at HD-SDI may introduce return loss, impedance irregularities, or attenuation problems at 12G that are invisible in testing but catastrophic in production. The 268875006 eliminates that risk with a construction specification verified for 12 Gb/s UHDTV performance — making it the correct coaxial choice for integrators and contractors specifying video infrastructure that needs to carry today’s UHD signals without compromise.
Silver-Plated Solid Centre Conductor for Maximum Signal Integrity
The 268875006 uses a silver-plated oxygen-free copper solid centre conductor at 1.02 mm diameter (AWG 18, 0.79 mm²). Silver plating is a deliberate engineering choice at this performance tier — silver has lower surface resistance than bare copper at high frequencies, which matters significantly in 12G-SDI transmission where skin effect concentrates current flow at the conductor surface. The result is lower attenuation at high signal frequencies, which directly translates to longer reliable transmission distances and improved signal quality compared to unplated copper equivalents.
The solid construction contrasts with the stranded conductors used in Van Damme’s flexible coaxial cables. Where a stranded centre conductor optimises for repeated flexing and touring use, a solid conductor optimises for electrical performance over longer fixed runs — lower resistance, tighter impedance control, and better high-frequency attenuation characteristics. For permanent installation runs between cameras, routers, distribution amplifiers, and monitors in broadcast and AV infrastructure, solid core is the correct specification.
Dual-Layer Screening for Clean 12G-SDI Transmission
The 268875006 uses a two-layer screening architecture designed to maintain signal integrity in electrically demanding broadcast and production environments. The first screen is a bonded aluminium and polyester foil at greater than 100% coverage, providing a continuous barrier against external electromagnetic interference along the full cable length. The second screen is a tinned oxygen-free copper braid at greater than 95% coverage, adding structural screening continuity and providing the return current path that coaxial video signals depend on for proper impedance control.
Together, the dual screens protect 12G-SDI signals from the interference sources common in broadcast and live production environments — power distribution, lighting infrastructure, wireless systems, and other broadcast equipment operating in close proximity. At 12G bit rates, where signal margins are tighter than at lower SDI formats, screening quality directly affects the integrity of the video signal at the receiving end of the run.
Backwards Compatibility Across All SDI Formats
One of the practical strengths of the 268875006 is full backwards compatibility with the complete hierarchy of SDI video formats. A cable specified today for 12G-SDI infrastructure will carry 6G-SDI, 3G-SDI, HD-SDI, SDI, and analogue video signals without degradation. This matters for real-world broadcast and AV installations where cameras, routers, monitors, and signal processing equipment from different generations coexist on the same infrastructure.
The 268875006 supports the following video formats and standards: 4K single-link 12 Gb/s UHDTV (SMPTE ST 2082-1), 6 Gb/s UHDTV (SMPTE ST 2081-1), SMPTE 424M 3G-SDI, SMPTE 292M HD-SDI, SDI, and analogue video. Resolution compatibility includes 720p, 1080i, 1080p, 1080p120, and 2160p30 — covering the full range of formats in current production use.
Construction Built for Broadcast and AV Installation
The gas-injected foam skin polyethylene dielectric at 4.60 mm diameter provides the controlled impedance environment the solid centre conductor needs for consistent 75 ohm performance. The flexible PVC composite outer jacket in jet black (RAL 9005) at 6.95 mm overall diameter is heavy-duty without being unmanageable — appropriate for both equipment room rack builds and longer installation runs. The operating temperature range of -30°C to +75°C covers outdoor and indoor installation environments across Southern Africa’s climate range.
The 268875006 is the direct equivalent of Belden 4694R — a widely recognised benchmark in broadcast coaxial cable — giving integrators and consultants a familiar performance reference when specifying the Van Damme product into broadcast infrastructure alongside internationally recognised standards.
Verified 12G SDI Cable Performance and 268875006 Transmission Distances
Transmission distance on 12G-SDI cable is a function of signal format and attenuation. Higher bit rates attenuate more rapidly, so maximum distances decrease as you move up the SDI hierarchy. At 12 Gb/s, the 268875006 delivers reliable transmission to approximately 70 metres. At 6 Gb/s, performance extends to around 105 metres. Legacy SDI formats at lower bit rates support considerably longer runs on the same cable. All performance figures should be treated with a 20% derating tolerance to account for connector quality, installation conditions, and environmental factors.
