Fiber optic cables use wavelengths of visible light to transmit data. (Some use infrared as well.) They use red and above with the higher wavelengths being of higher speed and quality. The higher the wavelengths of light used, the more expensive the equipment is.

Is all electromagnetic radiation in the optical portion of the electromagnetic spectrum is visable?
Yes
The visible portion of the electromagnetic spectrum represent a large portion of the spectrum?
The visible portion of electromagnetic spectrum is called the visible light and is the electromagnetic wave with the wavelength between 380 - 740 nm.
What portion of the of the electromagnetic spectrum do radio telescope?
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
What portion of the electromagnetic spectrum do radio telescope use?
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
Which portion of the electromagnetic spectrum is used to identify fluorescent minerals?
The UV portion of the spectrum
What part of the electromagnetic spectrum is used in ovens?
In a microwave oven, we find that microwave energy (from the microwave portion of the electromagnetic spectrum) are used. In a conventional oven, gas or electricity is used to create infrared heat, so we find infrared radiation (from the infrared portion of the electromagnetic spectrum, which is just below the visible light or optical portion) used there. If the oven happens to be a combination microwave and conventional, we'll find both types of electromagnetic waves generated for use inside.
