Black 100 ft 75 ohm SDI Siamese BNC cable with woven shield and 18 gauge power pair

BZBGEAR

BZBGEAR BG-CAB-SDIS100 100ft 75-ohm SDI Siamese BNC Cable

SKU CH-K4HS-KZPNQ

A 100 ft shielded 75-ohm SDI Siamese BNC cable carries 1080P60 video plus DC power or RS232/485 control on a single run, sweep-tested at 3 GHz

  • Cable length100 ft (30.5 m)
  • Overall length100 ft (30.5 m)

Cable Length 100 Feet

  • Transmit 1080P60 video over 100 ft reliably
  • Carry DC power or RS232/485 with the video signal
  • Shielded 75-ohm coax rejects electromagnetic interference
  • 3GHz sweep tested for consistent signal quality
  • Siamese design reduces cable runs for faster installs

Ready-to-run 100 ft SDI siamese cable

This 100 ft BNC cable combines 75-ohm shielded coaxial video with an 18-gauge stranded copper pair so a single run carries both 1080P60 3G-SDI and DC power or RS232/485 control. It is built for installers and operators who need a dependable, pre-terminated link for cameras, switchers or recorders without pulling separate power lines.

Woven shield and tested coaxial core

The woven shield rejects electromagnetic interference to keep images free from artifacts across the full 100 m distance. Each assembly is 3 GHz sweep tested, confirming the 75-ohm characteristic impedance and reliable signal integrity for permanent installations or repeated temporary setups.

Integrated power and serial conductors

The bonded 2-conductor 18-gauge wire eliminates the need for a second cable to supply DC voltage or RS232/485 serial commands to the camera. This reduces labour, cable count and potential failure points in both fixed infrastructure and mobile production kits.

Questions about this item

What SDI standard does the 75-ohm cable support and what resolution does it cap at?

The cable is tested to 3GHz and supports 3G-SDI signals up to 1080P at 60 frames per second over the full 100 ft run.

What physical conductors are included in the Siamese construction for power or control?

It adds a 2-conductor 18-gauge stranded copper pair alongside the coaxial video core so DC power or RS232/485 serial control travels on the same run.

How do you terminate the cable and which step is commonly missed?

Connect each BNC plug to the video ports and attach the two flying leads to the power or serial terminals; the step often missed is matching polarity on the DC pair before powering the camera.
