Abstract:
1. A method, comprising detecting a wavelength collision in a network where multiple TDMA systems operate over a common laser transmitter; identifying a pair of optical network terminals whose laser wavelengths are closer together than several times a laser chirp of transmitters that transmit colliding wavelengths from the pair of optical network terminals; and recovering from the wavelength collision including re-adjusting wavelengths of the pair of optical network terminals that cause collisions to eliminate the wavelength collision by placing a wavelength of a laser of each optical network terminal device in different wavelength bins whose widths are greater than several times the laser chirp so that lasers in different wavelength bins do not optically beat with each other, wherein re-adjusting includes tuning remotely a wavelength of one of the pair of optical network terminals to a different wavelength bin.
