Coaxial cables and Optical Cables both are used for signal transmission – so how different are these types? Let’s read the article below to understand in details about the differences.
What are Coaxial Cables?
Coaxial Cables are the type of cables which has one conducting core wrapped by one non-conducting dielectric layer, which is wrapped around by a metal braid layer; the outer is an insulating sheath. “Coaxial” word means all the cable layers use the same geometrical axis.
What are Optical Cables?
Optical Cables are one type of Telecom cables which are made of glass or plastics, using light to transmit signals.
The cores of optical cables are made of transparent glass with the diameter of a hair. They are arranged into bunches called Optical Cables and are used for transmitting signals in very far distance. Unlike Coaxial Cables transmitting signals with electricity, optical cables are seldom interferential, their speed is high (This is the speed of signal transmission, distinguished from signal speed) and further transmission.
Features of optical cables:
Optical Cables has their features including central conductor is glass or plastics fiber which is refined in order to make the signal transmission of the light to be at the maximum level.
Optical Cables are coated with a layer of primer to reflect better the signals.
-/ Core: The reflective center of optical fibers where the light goes through
-/ Cladding: Outer optical material wraps the core, reflects the light back to the core.
-/ Buffer coating: Outer flexible coating protects the fibers from being damaged and wet.
-/ Jacket: Hundreds or thousands of optical fibers are put into bunches called Optical Cables. These bunches are protected by the outer coatings of cables named Jackets.
