POWRIG 12G-SDI 4K BNC to BNC Cable with 90° Right-Angle Connectors
The POWRIG 12G-SDI cable is a broadcast-grade 75 ohm coaxial BNC-to-BNC cable engineered for 12 Gbps data throughput — the bandwidth required for uncompressed 4K UHD video at up to 60 fps with HDR. Both ends feature 90° right-angle BNC male connectors that route the cable flush against the device body, making it ideal for camera cages, OB vans, rack-mounted switchers, and any setup where straight connectors would protrude and risk damage.
Available in four color-coded jackets — black, green, red, and blue — for instant cable identification in multi-camera live production environments.
Key Features
- 12 Gbps Bandwidth for 4K UHD — Supports the full SMPTE ST 2082 12G-SDI standard, delivering uncompressed 4K video at 24/25/30/50/60 fps over a single coaxial cable. Also backward compatible with 6G-SDI, 3G-SDI, and HD-SDI.
- HDR & High Frame Rate Support — Handles the increased data payload of HDR10 and HLG metadata as well as high frame rate signals (4K 50p/60p) without signal degradation or dropout.
- 90° Right-Angle BNC Connectors — Both connectors are 90-degree male BNC, routing the cable parallel to the device face. Extends only ~1 cm from the port — critical for tight camera cages, rack panels, and OB truck patch bays.
- True 75 Ohm Impedance — Precision-manufactured to 75Ω impedance with proper dielectric matching. Prevents signal reflections, ghosting, and CRC errors that plague 50Ω or poorly-made cables in SDI applications.
- Color-Coded Jackets — Available in black, green, red, and blue. In multi-camera productions, color coding allows instant identification of camera feeds (e.g., red = Camera 1, blue = Camera 2, green = Camera 3, black = ISO record).
- Gold-Plated Connectors — Corrosion-resistant gold-plated BNC pins ensure consistent signal conductivity and reliable mating over hundreds of connection cycles.
- Flexible Coaxial Construction — The cable jacket and internal conductor are designed for repeated bending and coiling on set without signal degradation or internal breakage.

Why Color-Coded SDI Cables Matter in Live Production
In multi-camera live productions, cable identification is critical for fast troubleshooting and routing. Industry-standard color coding helps crew members instantly identify which cable feeds which camera or signal path:
| Color | Common Assignment |
|---|---|
| Red | Camera 1 (main/wide shot) |
| Blue | Camera 2 (close-up / left angle) |
| Green | Camera 3 (close-up / right angle) |
| Black | ISO record / program out / backup feed |
Tip: For productions with more than 4 cameras, combine color-coded cables with numbered cable labels for full traceability.

Frequently Asked Questions
What is 12G-SDI and why do I need a dedicated cable for it?
12G-SDI is the SMPTE ST 2082 standard that carries uncompressed 4K video at up to 60 fps over a single coaxial cable at 11.88 Gbps. This is 4× the data rate of 3G-SDI. At these speeds, cable quality matters significantly — poor impedance matching, inadequate shielding, or wrong-gauge conductors cause CRC errors, signal dropout, and image artifacts. The POWRIG 12G-SDI cable is built with proper 75Ω impedance and shielding to handle the full 12G data rate reliably.
Can I use this 12G-SDI cable for lower-bandwidth signals like HD-SDI or 3G-SDI?
Yes. The cable is fully backward compatible with HD-SDI (1.485 Gbps), 3G-SDI (2.97 Gbps), and 6G-SDI (5.94 Gbps). A 12G-rated cable is over-engineered for lower bandwidths, which means even better signal integrity and longer reliable runs at HD and 3G speeds.
Does the 90° right-angle connector affect signal quality at 12G speeds?
No. The right-angle connector is precision-machined to maintain 75Ω impedance through the bend. There is no measurable signal loss or impedance discontinuity compared to a straight BNC connector at 12G data rates.
What is the maximum reliable cable length for 12G-SDI?
For passive copper BNC cables like this one, reliable 12G-SDI transmission is typically possible up to 50-70 meters depending on cable gauge and quality. At 50 cm, this cable operates well within safe margins with zero signal degradation. For runs over 70 meters at 12G, fiber optic SDI cable or an SDI-over-fiber converter is recommended.
Will this cable work with my Blackmagic ATEM switcher and URSA camera?
Yes. Any device with a standard BNC SDI port is compatible. This includes Blackmagic ATEM switchers (Television Studio, Constellation, Television Studio HD), URSA Mini Pro 12K, Pocket Cinema Camera 6K Pro (via SDI output), SmartView monitors, and all Blackmagic Micro Converters.
Why are there color options? Do different colors perform differently?
All four colors (black, green, red, blue) have identical electrical performance and specifications. The color coding is purely for cable management — it lets production crews instantly identify which cable feeds which camera in multi-camera live setups. This eliminates confusion during fast-paced switching and troubleshooting.
Can I use this cable for analog video or timecode?
Yes. The BNC connector and 75Ω impedance are compatible with composite analog video (CVBS), LTC timecode, and word clock signals. However, the cable's primary advantage — its 12G bandwidth — is only utilized with SDI digital video signals.
