Is optical fiber unidirectional?

The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.

What is optical communication?

An optical fiber is a flexible, transparent fiber made of very pure glass (silica) not much bigger than a human hair that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
