Optical label swapping and packet transmission based on ASK/DPSK orthogonal modulation format in IP-over-WDM networks

We demonstrate all-optical label swapping based on SOA, EAM and HNLF for a two-level optically labeled packet using orthogonal ASK/DPSK modulation format. The ASK/DPSK packet is successfully transmitted over 80 km NZDSF.
