Abstract
While subcarrier multiplexing (SCM) technology is effective in implementing optical label swapping,1,2 no field trial has been accomplished to date. All-optical header extraction and swapping using a fiber Bragg grating (FBG) has been shown to be dispersion and polarization insensitive.3 Conventional circuit switching achieves traffic add-drop at wavelength granularity. Packet switching can achieve sub-wavelength granularity in add-drop. Using the National Transparent Optical Network (NTON), we achieve the first field demonstration of optical label-based wavelength switching and packet drop.
