<p>An optical node (1) comprises:
a plurality of client interface modules (1.0) comprising a client-side port (7) for receiving a client service and a segmentation block (7) for segmenting the or each received client service into a plurality of data streams (11) at predefined data rates;
a plurality of WDM transponder modules (30) comprising an encapsulation block (35) for encapsulating the received data streams into transport data frames and a rate-adjustable modulated laser source (31) adapted to generate an optical signal (32) carrying the transport data frames at an adjustable transport data rate on a wavelength channel of a frequency grid; and
an electrical switch module (20) comprising a plurality of client-side ports (22) for receiving the data streams (11) at the predefined data rates, a plurality of network-side ports (23) for passing the data streams (11) to the adjustable WDM transponder modules (30), and a switch matrix (21) configured to create a plurality of transmission paths adapted to pass a respective data stream from the client-side port to the network-side port.</p> |
