Abstract

We propose a wavelength allocation method for bidirectional transmission in a coarse wavelength division multiplexing channel. The method can be accommodated by assigning a different upstream wavelength from the downstream wavelength at room temperature to eliminate penalties induced by backscattering, including Rayleigh backscattering. We suggest a procedure to obtain the minimum wavelength difference.
