Abstract

A method () of operation in a passive optical network system () includes transmitting wave division multiplexed data in a downstream link () of an optical distribution network () using a plurality of optical line terminals (). Each optical line terminal () operates at a unique wavelength, and is synchronized to each other optical line terminal by a common reference (). Upstream data is received from an upstream link () of the optical distribution network on a shared common upstream wavelength ().
