在高速、长距离光波通信上,色散始终是一个主要障碍。普通激光二极管发射多重频谱,经光纤长距离传播后,色散将使脉冲劣化,这就限制了跨距为20—30km、容量为400—500Mb/s的中继器在一般的1.3μ光纤系统中的使用。日本NEC公司最新研制的用于1.3 μ
Dispersion is always a major obstacle in high-speed, long-distance optical communications. Ordinary laser diode emits multiple spectrums and after dispersion over long fiber distances, dispersion will degrade the pulses, which limits the repeater with a span of 20-30km and a capacity of 400-500 Mb / s in a typical 1.3μ fiber system usage of.
