Abstract—In telecommunication, the Bit Error Rate (BER) is an indication of how often data has to be retransmitted because of an error. The different modulation techniques scheme is suggested for improvement of BER in fiber optic communications.
February 2013 , Volume 68, Issue 3, pp 907–919 | Cite as. Recently, fiber optical communication and OFDM method have been combined to obtain both advantages in a communication. In this study, Bit error rate (BER) versus distance variations are investigated for a constant signal to noise ratio in CO- OFDM systems.

This paper explains the technical issues that have been addressed during the past decade of Sampled Values technology development and explains how these issues are.
In digital transmission, the number of bit errors is the number of received bits of a data stream. The bit error ratio can be considered as an approximate estimate of the bit error. In a communication system, the receiver side BER may be affected by. bit synchronization problems, attenuation, wireless multipath fading , etc.
Free space optics works on the same principle as fiber optics technology, except that it uses air as a medium for transmitting information instead of fiber optic cables. Moreover, the setup for free space optics communication.
The receiver captures the infrared signal and directs it to the fiber-optic. from a Bit Error Rate (BER) test set. BER testing determines the number of errors in a signal caused by interference, noise, distortion or sychronization problems.
