Abstract

Laser source is an inevitable source for generating light waves which act as a carrier in wired or wireless medium. LED is a modulation source which reduces the wavelength in visible light medium. In this paper, different laser sources with free space channel and optical fiber in the wavelength of 1550μm are used to evaluate the performance of Quality Factor and Bit Error Rate (BER). The controlled pump laser, directly modulated measured laser and empirical measured laser are reviewed with free space and optical fiber channels. The corresponding modulated signal source is received and the maximum probability of quality factor and minimum bit error rate is determined. The reason for choosing the laser over LED is that the laser has more bandwidth and power efficiency and is compatible with both single and multimode fibers. Laser has higher SNR than other source of optical communication.
