摘要： Disclosed is a wide-band dispersion controlled optical fiber. The optical fiber enables the use of optical signals in various wavelength regions in a wavelength division multiplexing mode communication network by controlling the position of the zero dispersion wavelength, and enables long distance transmission by controlling dispersion slope and bending loss. Furthermore, there is an advantage in that the optical fiber enables not only short distance transmission but also middle/long distance transmission using a single type of optical fiber because the optical fiber is controlled to have negative dispersion values in the O-band wavelength region and positive dispersion values with small deviations in the C-band and L-band wavelength regions.
摘要翻译：公开了一种宽带色散控制光纤。该光纤通过控制零色散波长的位置，能够在波分复用模式通信网络中的各种波长区域中使用光信号，并且通过控制色散斜率和弯曲损耗来实现长距离传输。此外，光纤的优点在于，不仅能够实现短距离传输，而且还能够使用单一类型的光纤进行中长距离传输，因为光纤被控制为在O波段波长区域具有负色散值，在C波段和L波段区域中具有小偏差的正色散值。
