12G SDI Cable for Broadcast Video
This 25ft Belden 4694R coaxial cable carries 12 Gbit/s signals for 4K 60Hz and 8K quad-link workflows. Gold-plated BNC male connectors on both ends provide 75 Ohm impedance with low-loss transmission. The 18 AWG silvered copper conductor and 95% tinned copper braid shield suit professional SDI camera and switcher links. It is built for Ultra-High Definition Digital Video, 4K D-Cinema and HD-SDI 1080p applications.
Integration with Production Gear
The cable connects SDI cameras directly to video switchers, recorders, monitors or capture cards such as Blackmagic DeckLink 8K Pro and Video Hub units. Its CMR-rated PVC jacket meets in-wall installation codes for permanent studio runs. The foil-plus-braid shield rejects interference in dense rack environments. No external power or active circuitry is required; the passive design fits any standard 75 Ohm BNC port.
Upgrade from Lower-Rate Coax
Replaces legacy HD-SDI or 3G-SDI cables that cannot sustain 12 Gbit/s single-link 4K or 8K quad-link loads. The jump is worth it when moving to 4K 60Hz single-link acquisition or when an 8K workflow demands four synchronized 12G paths. It does not serve installations needing fibre-optic reach beyond copper distance limits or multi-camera setups requiring more than one cable per channel.

Questions about this item
How far can the Belden 4694R cable carry a 12 Gbit/s 4K 60 Hz signal without loss?
The 25 ft length is rated for 12 Gbit/s 4K 60 Hz transmission with low loss thanks to the 18 AWG silvered copper conductor and 95 % tinned copper braid shield.
Does the cable generate heat or noise when used continuously for live broadcast?
As a passive coaxial cable it produces no noise and negligible heat during sustained 12 Gbit/s operation.
What devices must already have BNC SDI ports for this cable to work?
Both the source and destination need 75 Ohm BNC SDI interfaces — for example an SDI camera and a video switcher, monitor, recorder or capture card.
