摘要 本文描述了超高信息通信业务的趋势下,为满足C+L应用波段的扩展,新定义一种新型光纤:CL光纤。研究了在不同截止波长下,CL光纤在C波段与L波段的衰减差值及衰减谱波形的变化,寻找最适截止波长,使得CL光纤在1520nm~1625nm衰减最小值与1520nm之间差值A、1520nm~1625nm衰减最小值与1625nm衰减值之间的差值B,A、B数值小,且两者之间尽量接近,来减少光信噪比(OSNR)的劣化。 Under the trend of ultra-high information communication,CL optical fiber,a novel type of optical fiber,is created to meet the extended application of C+L band.This paper studies the attenuation difference and the variation of attenuation spectrum of CL fiber in C-band and L-band under different cut-off wavelength in order to confirm the optimal cut-off wavelength which makes the difference,named A,between the minimum attenuation value of CL fiber in 1520nm~1625nm and 1520nm and the difference,named B,between the minimum attenuation value of 1520nm~1625nm and 1625nm as small and close as possible to reduce the deterioration of optical signal-to-noise ratio(OSNR).
