Patent

CA 2323028

An optical packet is provided with an amplitude modulated (ASK) payload and a differential phase shift keyed (DPSK) header so that a routing address in the header can be read and modified at a network node without having to inject light at this node to do this modification. With ASK, though it is easy to convert a high-level bit to a low-level bit by simple attenuation, the conversion of low-level bit to high-level bit requires light injection. With DPSK, bit conversion can be effected without light injection, merely requiring passage through a phase modulator.
