Transparent optical node structure

摘要

A transparent optical node (TON) structure for use in a two-connected optical packet switching architecture. The TON is used in an interconnect employing deflection routing with two wavelength signaling where the data information of the packet resides on one wavelength lambda 1 and the header information of the packet resides on a different wavelength lambda 2. The TON is capable of full switch functionality: packet routing, add/drop multiplexing and packet buffering. The header portion of the packet is removed from data portion and can be rewritten before reinsertion. This invention allows for the use of a previously developed TON to be used with two-wavelength signaling.
