The Nightmare of Signal Loss and Interference
You are in the middle of a live broadcast. The camera is rolling. The lighting is perfect. But suddenly, the monitor shows a glitch. The 4K image looks soft. There is ghosting in the picture. Or worse, the audio drops out during the key interview. This is the pain of using cheap cables. You buy low-quality wire to save a few dollars. But it costs you the whole project. Cheap cables have bad shielding. They pick up noise from lights and motors. They do not have the right impedance. This causes reflections. The signal bounces back. Your image fails. You need a cable that works every time. You need a cable built for the real world. You need the Japanese standard for broadcast quality.
What Makes CANARE L-5CFB the Industry Standard
CANARE is not just a brand. It is a legend in Japan. They are listed on the Tokyo Stock Exchange. This is a top-tier company. They make cables for broadcasters, stadiums, and theaters. The L-5CFB is their star product. It is a 75-ohm coaxial cable. It is designed for serial digital video (SDI). But it does more than video. It carries digital audio too. This is a true broadcast cable. It uses high-quality materials. The center conductor is solid copper. The insulation is foamed polyethylene (PE). This keeps the signal strong. The outer shield is tight. It stops noise from getting in. Every meter of this cable is tested in the factory. They sweep-test it up to high frequencies. If it fails, they reject it. This is why TV stations trust it. It is the “gold standard” for HD-SDI installation.
Technical Specs You Can Trust
This cable is built for high bandwidth. It handles 12G-SDI signals. This means it can carry 4K video at 60 frames per second. It also works for 3G-SDI and HD-SDI. Here is the real data you need:
- Impedance: 75 Ohms (exact match for video gear).
- Conductor: 18 AWG (1.05mm) solid copper-clad steel. Strong and conductive.
- Insulation: Foamed PE. Low dielectric constant.
- Shielding: Double shield with aluminum tape and braid. Coverage is over 93%.
- Attenuation (Signal Loss):
- At 10 MHz: Only 2.3 dB per 100m.
- At 100 MHz: About 6.5 dB per 100m.
- At 900 MHz (Satellite): Around 20 dB per 100m.
- Outer Diameter: 7.3mm. It is slim but tough.
- Capacitance: 52 pF/m. This keeps the signal shape clean.
- Environment: RoHS compliant. No lead. Safe for indoor use.
Where to Use This Cable
This wire fits many jobs. It is perfect for fixed installation in walls. It is also great for mobile use. Here are the top scenes:
- Broadcast Studios: Connect cameras to switchers. Run long lines without repeaters.
- 4K Production Trucks: Use it for patch bays and camera tails. It is flexible but durable.
- Satellite Head-Ends: It works for L-band and IF signals.
- Theaters and Stadiums: Run video to big screens. The shielding stops interference from power lines.
- Medical Imaging: Use it for high-res video feeds in hospitals.
- Audio Work: Use it for AES/EBU digital audio. It sounds crisp and clear.
