In this paper it is proposed a new architecture for N*N optical packet switching system. It consists of active-splitter type pf packet router, travelling type of optical buffer memory for packet contention resoltuion and an electronic controller. the BER performance of the proposed switching system is analyzed with respect to channel crosstalks and amplified spontaneous emissio noise form switching elements and optical amplifiers respectively. Operational validity of the proposed switching system is also experimentally proved by realizing 2*2 optical packet switching system.
