What is Fiber Optic Cable?
- A Fiber Optic Cable is used to transmit data through fibers (threads) or plastic (glass). This pack of glass which is within sorts of threads transmits modulated messages along sunshine waves. There are many advantages of using these cables over other kinds of communication cables, like the bandwidth of these cables is high, and they are less vulnerable than metal cables. The biggest disadvantage of these cables is their installation.
- A fiber optic cable is formed by drawing glass or a special sort of plastic, which can transmit light from one end of the fiber to a special end. glass fiber cables use light signals to transmit data signals instead of traditional electrical signals. Twisted pair cables use current to transfer data signals. Generally, there are three sorts of fiber optic cables: 2 glass fiber —single mode fiber optic cable, and multimode optical fiber, also as plastic glass fiber (POF).
- The “mode” in fiber optic cable refers to the trail during which light travels. Single-mode fiber features a smaller core diameter of 9 microns (8.3 microns to be exact) and only allows one wavelength and pathway for light to travel, which greatly decreases light reflections and lowers attenuation.
- Multimode optical fiber features a bigger core diameter than that of single-mode fiber optic cable, which allows multiple pathways and a variety of other wavelengths of sunshine to be transmitted. Multimode optical fiber is out there in two sizes, 50 microns and 62.5 microns. it’s commonly used for brief distances, including patch cable applications like fiber to desktop or patch panel to equipment, data and audio/video applications in LANs. consistent with fiber index of refraction distribution, multimode fiber are often divided into two types: Step-Index Multimode Fiber vs Graded-Index Multimode Fiber.
- POF may be a large core step-index glass fiber with a typical diameter of 1 mm. Massive size enables it to easily couple many light from sources and connectors that do not need to be high precision. So typical connector costs are 10-20% the utmost amount as for glass fibers and termination is simple. Being plastic, it’s more durable and should be installed in minutes with minimal tools and training. For applications don’t require high bandwidth over great distances, POF is more competitive, making it a viable option for desktop LAN connections and low speed short links.
Advantages and Disadvantages of Fibre Optic Cable
The usage of optical fiber cables has significantly advanced in data transfer and telecommunications. These cables employ the speed of light to carry data very quickly and reliably over long distances. They can be made from microscopic glass or plastic fiber. The foundation of optical fiber cables has completely changed the way we exchange, connect, and modify data in digital technology.
