No. Fiber is immune to electrical interference; there is no cross-talk between signals in different cables and no pickup of environmental noise.
Increases with length and connections.
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
Optical fiber is immune to electrical noise, interference and distortion. The bandwidth or capacity of optical is far greater than electrical transmission.
Fiber optics, using optical fiber, are specially designed to implement total internal reflection. A signal passed from one end of the fiber to the other end of the fiber is a single beam of light that repeatedly bounces off the edges of the fiber until it reaches it's destination. By scratching the outside of an optical fiber, this property can be disrupted causing the signal to be lost.

Usually, there is a laser diode that is optically coupled to the fiber.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
Describe refraction and reflection with respect to Fiber Optical Cable?
Optical fiber's main advantage over regular electric cables is that they don't experience electromagnetic interference of any kind, thus allowing signals to be sent where regular cables would get cut off. Another important advantage is that distance affects electric cables' data bandwidth much more severely than it does optic fiber.
