Fiber Optic Technology Frequently Asked Questions

Post by DDmallforum » Wed May 08, 2019 2:36 am

1. What is optical fiber?

Optical fiber is a glass or plastic filament that guides a light wave along its path.

2. What is singlemode fiber?

Singlemode fiber is optical fiber that allows light to travel down a single path known as the fundamental mode. It features a core diameter of 8 to 9

microns. Singlemode fiber can be used to transmit AV signals over extreme distances up to many miles or kilometers.

3. How does DDMALL handle analog video signals in its fiber optic products?

DDMALL fiber optic products convert analog signals to digital signals for an all-digital transmission of video, audio, and control signals. Converting the

analog video signal to a digital signal for optical transmission ensures the highest quality video.

4. What AV applications require fiber technology?

Fiber optical technology is ideal when transmitting video, audio, and control signals over long distances, in secure or hazardous environments, or

anywhere where it is important to future-proof an AV system. Long distance transmission makes fiber optic products ideal for installation in stadiums,

college campuses, medical facilities, corporate campuses, performing arts centers, concert halls, and office buildings. Low signal emissions make

fiber optic products preferred for secure environments such as military or government applications. Fiber optics is the ideal technology for

multi-gigabit digital video standards, ensuring that an AV system is upgradable to future standards.

5. What are the advantages of fiber AV systems in large venues and long haul transmissions?

Optical fiber is low-loss compared to electrical wire, and can transmit a signal over very long distances without the need of a repeater. Comparatively,

optical transmission is lower in cost than electrical transmission for long distances.

6. What types of fiber optic products does DDMALL offer?

DDMALL offers HDMI over fiber optic extender, SDI over fiber optic extender, CVBS over fiber optic extender and Duallink fiber optic extender.

DDMALL products enable long-haul transmission of HDMI, Duallink DVI, , high resolution RGB and standard definition video, as well as audio and

RS-232 control over fiber optic cable at extreme distances up to 20 km (12.43 miles). For more details about the products, please visit:
