Abhishek Sharma, Sukhbir Singh, Bhubneshwar Sharma . Investigations on Dispersion Compensation using Fiber Braggs Grating. International Journal of Computer Applications. 73, 2 ( July 2013), 34-43. DOI=10.5120/12715-9529
Optical fiber plays a very important role in communication system for data transmission. Optical fiber has many advantages which makes it for better transmission of data. Dispersion is the main factor which affects the performance of fiber. There are various ways which can compensate the fiber dispersion. Dispersion compensation by FBG (fiber bragg grating) is one of them. This paper investigates dispersion compensation of optical communication system by FBGs along with EDFA (erbium doped fiber amplifier). Dispersion compensation is done by FBG along with EDFA before the fiber (at the transmitter end) in the optical transmission system and FBG along with EDFA after the fiber (at the receiver end) in the optical transmission system. Minimum BER is obtained by using FBG along with EDFA before the fiber (at the transmitter end) in the optical transmission system as compare to FBG along with EDFA after the fiber (at the receiver end) in the optical transmission system. For 50 km BER reduces from 1. 10874e-102 (at receiver side) to 4. 16583e-181 (transmitter side).
