- Belden 1694A 18 AWG coax keeps signal loss low over long runs
- Gold-plated 75 ohm BNC plugs ensure reliable contact
- 5 GHz bandwidth supports 12G-SDI at 11.88 Gbps
- Carries SD-SDI, HD-SDI, 3G-SDI and 6G-SDI formats
Professional SDI interconnect
This 50ft Belden 1694A cable carries 12G-SDI at 11.88 Gbps with 75 Ohm BNC male plugs on both ends. Gold-plated contacts and 18 AWG solid centre conductor suit studio cameras, recorders and switchers needing a single long run.
Bandwidth ceiling at 4.5 GHz
The RG-6/U coax is specified to 4.5 GHz, so 12G-SDI at 11.88 Gbps sits at the cable's upper limit; longer runs or tighter bends may push attenuation past the receiver's equaliser range. Installers should verify eye-pattern margin before committing to permanent routing.
12G-SDI compliance decides fit
If the workflow stops at 6G-SDI (5.94 Gbps) a thinner cable may suffice, but 12G-SDI (ST 2082) demands this 1694A construction to maintain the required signal integrity over 50ft.

Questions about this item
What length should I choose for my SDI run?
The cable is supplied in a single 50ft length using Belden 1694A 18 AWG coax, designed for long SDI runs with low attenuation.
What does the 12G-SDI rating mean for my 4K workflow?
It supports 11.88 Gbps (ST 2082), carrying 4K and 6K video over the 75 Ohm BNC link without compression.
How does the 4.5 GHz bandwidth affect the maximum signal I can send?
The 4.5 GHz bandwidth of the Belden 1694A coax supports the full 12G-SDI 11.88 Gbps rate over the 50ft distance.
