<p>A node (20) of a wavelength division multiplexed passive optical network (WDM-PON) comprises wavelength division multiplexing optical line termination (OLT) apparatus (22). The OLT (22) has an optical interface (23) for interfacing with a plurality of remote optical network units (11) in a passive optical network using a plurality of different wavelength channels (?). The OLT (22) has a plurality of electrical first ports (24) corresponding to the optical wavelength channels (?). A plurality of second ports (33) interface with at least two operator networks (40-42). An electrical switching matrix (30) interconnects the first ports (24) and the second ports (33), allowing any operator (40-42) to access any subscriber in a point-to-point manner. The apparatus at node (20) can be formed as a plurality of modules (25).</p>
