Flexible Waveband Optical Networking Without Guard Bands Using Novel 8-Skip-0 Banding Filters
01 March 2005
Novel 5-band 8-skip-0 band filters realized in silica waveguide planar lightwave circuit technology were successfully used to demonstrate versatile wavelength division multiplexed optical networking. 40 C-band channels spaced 100 GHz apart grouped in five bands of 8-channels each allowed WDM networking without loss of any channel within the available optical bandwidth. We demonstrate simultaneous transport of 10-Gb/s and 40-Gb/s with rate-appropriate optical add-drop nodes.
