摘　　要：描述了4端口8波长光突发交换光纤传输系统的设计方案,提出了一种新的光突发交换光纤传输系统的波长设计方法,在满足光突发交换要求的同时,降低了实现难度和成本;设计了适用于光突发交换光纤传输系统的突发模式光发射机和接收机,在系统传输速率为1．25 Gb/S的突发数据包时,实现了发射平均光功率优于-2 dBm、接收灵敏度优于-23 dBm、动态范围大于15 dB、突发同步时间小于6μs、保护带为6μs．In this paper, a design of optical fiber transmission system of 4-port and 8-wavelength opticalburst switching network is described. A novel scheme of wavelength channels is mentioned, and it is fit for OBS network and reducing difficulty and cost of the network. Burst mode transmitter and receiver are designed for OBS. At 1.25 Gbps bit rate transporting packets, output optical power of transmitter is more than -2 dBm, input optical power of receiver is less than -23 dBm, dynamic range is more than 15 dB, b...
