Abstract

Optical fiber's zero-dispersion wavelength and lowest-loss wavelength depends on its physical and chemical structure, such as core and cladding materials. In future optical communication network, each local fiber can have its own most- suitable wavelength for information transmission. Then connection of different kind of fiber will appear at any nodes of network. When information from one channel (say A), with carrier frequency most suitable for the fiber used in channel A, is simply transferred to another channel B with different fiber, some kind of degradation is expected on the information during its transmission through channel B. Obviously convenient wavelength device applicable at such fiber nodes is desirable, with conversion frequency customizable for each node.
