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.
There are actually about 10 types of Fiber Optic Cables. OFC: Optical fiber, conductive OFN: Optical fiber, nonconductive OFCG: Optical fiber, conductive, general use OFNG: Optical fiber, nonconductive, general use OFCP: Optical fiber, conductive, plenum OFNP: Optical fiber, nonconductive, plenum OFCR: Optical fiber, conductive, riser OFNR: Optical fiber, nonconductive, riser OPGW: Optical fiber composite overhead ground wire ADSS: All-Dielectric Self-Supporting
An optical laser is modulated and used as the transmitter in optical fiber communication.
it is the creteria for the number of modes in optical fiber

An optical fiber sensor can be used for just about anything a "regular" sensor can be used for. There are hundreds of sensors, and they can be made to communicate over optical fiber.
A transmitter sends light down optical fiber
A break in the cable would interrupt signal in optical fiber.
Optical fiber is conducting light, not electricity.
Optical fiber is not sensitive to electrical, magnetic or static interference
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
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? "
The advantage of wireless communication over optical fiber are as follows : the cost of wireless communication is much less over optical fiber communication : unlimited no of users can be installed which is not so easier in Optical fibers : maintanence of wireless communcation system is cheaper than Optical fiber communication.
· Installation/maintenance - It is a quite new technology. Installation and maintenance need knowledge that is not yet available everywhere. · Unidirectional - Propagation of light is unidirectional. If we need bidirectional communication, two fibers are needed. · Cost - More expensive than of other guided media. Physical vibration will show up as signal noise..and difficult to splice.

difference between fiber optical and free space optical
Describe refraction and reflection with respect to Fiber Optical Cable?
Optical fiber is immune to electrical noise, interference and distortion. The bandwidth or capacity of optical is far greater than electrical transmission.
An optical fiber is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers.
No. An optical fiber is a slim hair composed of glass. Glass is a fine insulator, and an optical fiber doesn't conduct electricity at all.
no, its cylindrical
optical fiber, is light transmission tools using of light in glass or plastic fibers on the principles of total reflection of light to achieve transmission Optical fiber is a flexible see through fiber made of extruded glass. This glass is slightly thicker than a human hair.
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
there are two types of optical fiber,the first type is single mode fibers.the second type is multimode fibers.
An optical fiber cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed.
#Optical fiber consist of a central core made of class or plastic which is surrounded by a cladding of material of refractive index slightly less than that of core and a protective jacket of insulating material. There are three types of optical fiber configuration.
This could be called an optical fiber diagram.
optical communication is the branch of engineering which deals with light.
The purpose of splicing optical fibers is to join two lengths of optical fiber. This may be practical when repairing a damaged length, or adding length to an existing fiber.

There are two basic types of optical fiber. Multi Mode Optical Fiber Used to transmit many signals per fiber. (Multi Mode fibers are generally used for computer networks, lan applications). MultiMode Optical Fiber is produced as 50/125 and 62.5/125. (Core/Cladding diameter in microns.) Single Mode Optical Fiber Used to transmit one signal per fiber (Single Mode fibers are generally used for telephone and cable tv applications.) Single Mode Optical Fiber is produced as 8/125 and… Read More
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.

optical bandwidth = 0.707 electrical bandwidth
Yes, they are the exact same thing
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.
No. Optical fibers only transmit light.

Ethernet fiber Media Converter(fiber optical media converter) translates signals from a twisted-pair 10/100Base-Tx to 10/100Base-FX fiber optical cable.
A definition on top of my head, it's the number of frequencies allowed to be carried by the Optical Fiber Cable, It depends on the Ko, thickness and Numerical Aperture of the Fiber Cable.
