With the growth of video traffic, image quality improves, the caliber of the fiber optic cables used for broadcast transmission and reception is more vital than ever before.
Broadcasters are shifting from copper cables to fiber optic cables for various reasons, such as high-speed performance and reliability in real-time. New technologies like 4K or 8K Ultra HD TV (also called Ultra HD and UHD TV) and Internet Protocol TV (IPTV) have brought shows such as the Olympics and live music into the homes of the standard viewers.
Ian Davies, broadcast sales engineer at Cliff Electronics, said the broadcast industry believes that the technology for picture quality currently in use can’t be upgraded. “Today, four-digit resolution is the standard, and 8K can send more signals to the fiber; however it does not affect the quality of viewing,” he said. “HD isn’t going to be enhanced further. It’s now as sharp as can be observed with your naked eyes. “
In addition to its clarity In addition to transparency, fiber optics provide flexibility. Fiber optic cables can be bent in tight spaces like out-of-broadcast (OB) trucks. It also is much lighter than copper, which makes it more efficient to transmit data from one broadcast location to another. Additionally, fiber optic cable offers more significant electromagnetic interference (EMI) protection and more excellent bandwidth handling over more considerable lengths of distances than copper. Different types of signals can be multi-channeled using a single fiber optic cable.
fiber optic cable Transmission
Systems that use fiber optics transmit signals via the thin glass fiber bundle comprising the center (a tiny glass central) as well as a covering (an optical coating that covers that core) and buffer coat (a transparent plastic layer that shields the fiber from moisture and damage). They have a total diameter of approximately 100 millimeters. (Glass is much less thick than plastic fibers. They are called in the field optical plastic fibers, also known as POF.) The electrical signal input is transformed into a sequence of light-based pulses carried along the cable by the laser. It is then converted back into one electrical signal after the final point. Multiple digital signals can be transmitted simultaneously via one fiber optic cable.
