摘要
Abstract
The power penalty induced by PM-AM conversion noise is evaluated by calculating its power spectrum at receiving end and using Personick-CCITT BER calculating method. Experimental results of 2.5Gb/s 300 km transmission are also presented to show the effects of the noise. The relationships between SBS threshold and laser linewidth in ASK(amplitudeshiftedkeying) modulated systems are analyzed. In designing high speed externally modulated systems, the transmission limitation set by both of effects usually must be considered.
