Long Distance signal transmission!
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.

An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. 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 communications

Optical Fiber Cable.
An optical splitter as its name suggests splits light. This is commonly used for splitting fiber optic communications for either business communications or for those who have fiber optic television and phone services at home.
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? "
Optical networking hardware entails the various components used in optical technologies. Some of the common hardware include routers, optical fiber, electronic devices and so much more.
