ABSTRACT:
Dependence on wavelength makes it difficult to lengthen the distance while increasing the density of wavelength division multiplexing. An optical signal expander module for a group of wavelength bands in a transmission system is provided and configured to solve the problem of dispersion and to achieve both a longer distance and higher density of wavelength division multiplexing that can be traded off.
