Definition: An optical fiber is a thin flexible strand made up of glass(silica) or plastic that is used for transmitting optical (light) signals. Usually, the diameter of the optical fiber is more as compared to human hair. More specifically, we can say that it is a waveguide that has the ability to transmit electromagnetic waves …
Definition: Step index fiber is a type of optical fibers that holds its classification on the basis of refractive index. Step index fiber is that optical waveguide, that has a constant refractive index within the core and another constant refractive index within the cladding. The refractive index of the core is somewhat more as compared …
Definition: An optical component that permits the propagation of the light signal in one direction only and completely blocking the other direction is known as Optical Isolator. Faraday effect is the basis of working of this device. Basically, when a light ray is allowed to pass through the fiber then there are some chances that …
Definition: Optical Modulation is the process by which a light wave is modulated (modified) according to a high-frequency electrical signal that contains information. These modified light waves are then transmitted either by a transparent medium or through an optical fiber cable. More specifically, we can say that it is the process by which an electrical …
Definition: Optical Line Terminal or optical line termination is a device that basically acts as a part of a passive optical network (PON). It is present in the central office of the network and manages the transmission and reception of information across the overall network. Optical line terminal is abbreviated as OLT. OLT do so …
Both semiconductors and superconductors are the two categories of materials that offer conductivity. However, the level of conductivity offered by the two crucially differentiates the two. The significant difference between semiconductors and superconductors is that in the case of semiconductors, the conductivity ranges between conductor and insulator. As against superconductors are the materials whose level …

Shunt and series voltage regulators are the two classifications of linear voltage regulators. The crucial difference between shunt and series voltage regulator is that in the shunt voltage regulator, the control element is in parallel connection with the load. On the contrary, in the series voltage regulator, the control element is serially connected to the …

Symmetric and Asymmetric multiprocessing are the two major classifications of multiprocessing as both include the use of multiple processors for system operation. The significant difference between symmetric and asymmetric multiprocessors lies in the way multiple processors are utilized by the system or we can say, the way multiple processors operate within the system. In symmetric …

Both charge and mass are the properties of matter. The significant difference between charge and mass is that charge has a classification. As against, the mass has no further classification. Charge mainly exists in two types positive and negative but mass can never be negative, it is always positive. A charge is a component that …
Definition: The term dispersion is widely used when we talk about travelling of light pulse, more specifically we can say light-wave transmission. Dispersion in an optical fiber is the spreading of light pulses when the wave travels through an optical fiber from an end to another. It results in some variation of the actually transmitted …
