yes, the ability of light to travel through the cable is what makes it useful. There is not some sort of hole in the center of the cable, it is a solid glass cable.

How do fiber optics work?
basically, the cable uses something called the critical angle, to keep light inside it. This means the cable can be bent while still allowing light to travel through it.
What is the name of the process that allows light to travel down a fiber optic cable?
Internal reflection
Will water pass through the core of a fiber optic cable?
no the core of a fiber optic cable is made of solid glass, making it impossible to pass anything but light through it.
What is mode in optical fiber?
mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.
What is the speed of light travel through fiber optics?
200,000,000 metres per second
What are 3 uses for light sent through a fiber optic cable?
Looking on your HCOS page.... instead of here.
Why do signals in the fiber optics cables travel at the speed of light?
fiber optics transfer data at the speed of light because that's exactly what is transmitted through them... light. fiber optic cables are thin pieces of glass that transmit light pulses
Can alternating current be transmitted through fiber optic cable?
No. Nor can direct current, for that matter. Fiber optics is designed to transmit light signals, not electrical currents.
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 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
Which light travel fastest in optical fibre?
All electromagnetic radiation (light) travels at a constant speed through whatever medium it encounters. Light in a vacuum, for instance, is about 186,282 miles per second; whereas in a fiber optic cable it chugs along at only 115,000 miles per second.
Which light travels faster in an optical fiber - ultraviolet or infrared?
Neither. All electromagnetic radiation (light) travels at a constant speed through whatever medium it encounters. Light in a vacuum, for instance, is about 186,282 miles per second; whereas in a fiber optic cable it chugs along at only 115,000 miles per second.*What distinguishes ultraviolet from infrared is the amount of energy associated with it, reflected in its frequency. Assuming that a particular cable is transparent to both forms of radiation (which may or may not actually be the case, as another name for infrared radiation is heat) it is likely that the ultraviolet energy would travel farther before its signal would need to be reboosted.*The speed of light through a medium is proportional to its index of refraction. The index of refraction of fiber optic cable is about 1.62; this means that light travels through it only about 60% as fast as it does through outer space.
