RESEARCH OF OPTICAL FIBER COMMUNICATION IN RELAY PROTECTION

Applications of optical fiber in relay protection

Because relay protection plays a significant role in the entire power system, optical fiber communication is generally used as the physical transmission channel of the relay protection device to protect the signal. In this paper, the main technology of optical differential protection, in the process of 6 KV power distribution system reform is how to apply this situation are introduced in detail, at the same time, a detailed description of the relative performance for the optical fiber differential protection. Optical fibre measurement is advancing, vari ous techniques in optical signal pro cessing are still under development and therefore there is still much research to be carried out into the applicability to the power industry.

Optical signal strength in fiber optic communication

Extinction Ratio (ER) significantly impacts signal performance in optical fiber networks. Simulation results show XPM suppression improves data transmission rates by approximately 1. Optical loss is measured in "dB" which is a relative measurement, while absolute optical power is measured in "dBm," which is dB relative to 1mw optical power Loss is a negative number (like –3. Silica fibers mainly used due to their low intrinsic absorption at wavelengths of operation. Optical fiber consists of a cylindrical core that propagates light and a concentric cladding that surrounds it. Abstract: There has been an unusual drop of Fiber Optics Broadband (FOB) internet speed in certain localities in Ghana which severely affect users' experience.

Q value in optical fiber communication

The Q factor measures the signal-to-noise ratio at the decision point in a receiver's circuitry. The purpose of this application note is to show the relationship between the electrical and optical signal-to-noise. There are so many different types of modulati n techniques scheme is recommended for improvement of BER and Q-factor in fibre optic communications.

Phase velocity along the x-axis in optical fiber communication

It is the value that determine the practical "velocity" of the transmission of the information (energy) in the fiber A typical value of S for standard fiber at zero dispersion wavelength is S=0. Chromatic dispersion is the phenomenon that the phase velocity and the group velocity of light propagating in a fiber depend on the optical frequency. Abstract Optical communication systems have evolved over the years from simple intensity modulation and direct detection systems to those involving modulation of amplitude, phase, polarization and transverse modal pro-file. Ray Theory – Light travels along a straight line and obeys laws of geometrical optics. Ray theory is valid when the objects are much larger than the wavelength (multimode fibers) Fiber optic cable functions as a "light guide," guiding the light from one end to the other end.
