This 50‑metre SDI coaxial cable is engineered for professional video signal transmission over long distances—ideal for broadcast trucks, live production rigs, studios or mobile setups. With a characteristic impedance of 75 Ω, it’s designed to maintain signal integrity for SD‑SDI, HD‑SDI, 3G‑SDI, 6G‑SDI and even 12G‑SDI formats (depending on specification).
Key aspects include:
- A heavy‑duty construction: typically a solid or stranded copper inner conductor, foam‑dielectric insulation and a dense dual (or more) braided copper shield with a robust outer jacket—often designed to withstand stage or outdoor use.
- Excellent shielding and low attenuation: The cable construction minimises signal loss (attenuation) over the length, reduces electromagnetic interference (EMI) and ensures clean video output even at high bit‑rates and resolutions.
- Long‑run capability: At 50 m, this length provides the flexibility to connect cameras, switchers, monitors or projectors which are relatively far apart, without resorting to multiple shorter runs or intermediate amplifiers—provided the cable’s spec supports the required video format.
- Professional connectors: The cable features BNC male‑to‑male 75 Ω connectors, enabling standard SDI inter‑connection with broadcast‑grade cameras, routers, distribution amplifiers or recorders.
- Durable mounting and handling: Many versions are built with rugged outer jackets to cope with repeat set‑up/tear‑down, coiling, transport and stage use. This means care is still needed to avoid excessive bends, sharp kinks or crushing which can degrade performance.
In practical terms, this cable allows you to run a single link of SDI signal over 50 metres while retaining image quality. However, it's important to match the cable’s rating to your signal format: high‑bandwidth signals (e.g., 12G‑SDI for 4K60) demand higher grade cable (lower loss) and proper terminations. Using a cable beyond its bandwidth or distance rating can lead to signal drop‑outs, distortion, or jitter.
