Abstract :
Power penalties in bit error rate due to limited transmission bandwidth are studied theoretically and experimentally. for less than a 0.5 dB penalty, a transmission bandwidth of 1.25 times the bit rate is required. If there are n components contributing equally to the transmission bandwidth, each of these components should have a bandwidth 1.25¿n times the bit rate.
