As users demand continues to grow, the transmission capacity of optical fiber communications also will be growing rapidly. Communications network switching nodes of light - electricity - light conversion caused by the \All-optical packet switching network (OPS) as a novel and effective optical domain switching solution has broad application prospects. Optical buffer as all-optical packet switching networks to overcome the \This paper has proposed bicyclic coupling optical buffer solution , based on a transparent semiconductor optical amplifier gain (GT-SOA) Alternative 1550nm semiconductor optical amplifier , a new method for the realization of optical buffers , while maintaining the original program structure is compact, \write \This paper also presents GT-SOA -based wholly bare switching programs, which are based on semiconductor optical buffer study presents a new idea has a certain research value. This thesis bicyclic GT-SOA -based fiber optical buffer (DLOB), is in the original horizontal \effect to achieve a new \Determination of the first performance GT-SOA , found 1550nm optical signal for the gain and the gain -independent transparency effects , observed the phenomenon of polarization rotation , and through a series of experiments , including the signal light and control light synchronization experiment , the optical switch experiments loop length measurement experiment , the cache read and write experimental realization of the data frame buffer ; cache structure and detailed research, the improvement program in achieving loop power compensation while avoiding the \In addition, based on the implementation of the NOLM ring GT-SOA optical switch and optical switch polarization rotation , to obtain the desired results .
