Abstract
A system includes an optical fiber cross-connect module with upstream ports and downstream ports, a first set of optical fibers connected from optical line terminals to the upstream ports, and a second set of optical fibers connected to the downstream ports and a customer optical network unit. The optical line terminals provide multiple wavelengths carrying optical signals at different bitrates over the first set of optical fibers. The customer optical network unit includes a tunable filter configured to receive any one of the multiple wavelengths. The optical fiber cross-connect module divides the optical signals received at each of the upstream ports into each of the downstream ports, and the customer optical network unit may be tuned to pass through a particular wavelength from the multiple wavelengths.
