Cascaded operation of optical label swapping using optical carrier suppression, separation and without regular wavelength converter in a multi-hop label switched optical network

We demonstrate cascaded optical label swapping using optical carrier suppression and separation technique without requiring conventional wavelength converter in a multi-hop OLS network carrying 10 Gbps DPSK payload and 2.5 Gbps OOK label over 300 Km SMF fibers. (2 pages)
