Hi, Fiber Optics transmit signal using lights rather than electic current, so when signal passes though an optical fiber cable, it does not generate electric or magnetic field around it, and it is not affected by surrounding magnetic or electric fields Adv of optical fiber is that they are immune to noise, signal passes at lights speed, and no signal power is lost along the transmission line.

Difference between metallic sheath and armour in cable?
The metallic sheath prevents the ingress of moisture, while the armour protects the cable from damage from foreign objects.
How are fiber optics used in medicine?
It is used by cable going up the anal and lighting up the inside.
What are the cost of fiber optics cable?
well, the scientists made it to save alot of money not 100% sure im doing it for my homework 2 lol ;) but gl
What is difference between core cable and pair cable?
The term core represents each individual conductor within a cable, and a pair is two cores (or two conductors) within a cable. For example if you have a 3 core cable, then the cable has 3 separate conductors in it (3 separate cables within the PVC coating). A 3 pair cable would be 3 sets of 2 cores, so this would have 6 conductors within the cable.
Why should the light ray be reflected rather than refractive in fiber optics?
Firstly, a fiber optic cable transmits light from one end of the fiber optic cable to the other end. You can kind of think of the fiber optic cable as a long tube. The way in which light travels from one end to the other is that it gets reflected off the inside parts of this glass or plastic tube by a physical phenomenon known as: Total Internal Reflection. Refraction of light only occurs when light travels from one medium to another. For example, when light travels from air to water, from water to air, from water to oil, etc. In other words, in terms of fiber optics, the only way light will get refracted is if it passes through the glass or plastic tube. But if this happened, then the light will exit the fiber optic cable as it travels from one end of the cable to the other end, and the light would not be properly transmitted, defeating the purpose of fiber optics. In other words, light should be reflective rather than refractive in fiber optics in order for light to be effectively transmitted from one end to the other end of a fiber optic cable.
What is the difference between the guided and unguided?

What is the difference between armored cable and mc cable?
The difference between Armored cable and Metal Clad cable is that the MC cable has a EGC (Equipment Grounding Conductor). Both cables are armored, and look almost identical so watch out.
What is the diffirence between Cross cable and state cable?
The difference between a cross cable and a state cable is that a cross cable, or crossover cable, is used specifically to connect two of the same devices.
What is unguided communication medium?
A guided communication medium is a space be mostly of solid state such as wires , where tranmission/recieveing data is only carried out within the space that the medium occupies. In the case of a wire, it's volume. Transmission is restricted to that particular space, thus it is called a guided communication. Example of this types of medium inlcude the coaxical cable, fiber optic cable, twisted pair cable...

What is the difference between broadband and DSL internet if any?
DSL is considered to be broadband speed. There is a difference in speed between DSL and Cable. Cable is generally much faster.
What exactly is a fiver optics cable?
Fiber Optics is a means of carrying electronic information through a cable that has a glass core. Light signals are used through the cable. It is a very high speed medium as well. For more info check out www.wikipedia.com
What are three ways that you use fiber optics?
Three ways that you can use fiber optics are: Cable Television, Computer Networking, Electronics Engineering
What difference between copper cable and optical cable?
A copper cable transports electrical signals. An optical cable transports light signals.
