Clear channel transmission of ATM/SONET and subcarrier multiplexed signals in a reconfigurable multiwavelength all-optical network testbed

Simultaneous transmission of subcarrier multiplexed multichannel FM-video and 3-GHz binary phase-shift keying (BPSK) digital signals, co-propagated with ATM/SONET multimedia services has been demonstrated for the first time in a reconfigurable multiwavelength all-optical network testbed. The experiment was performed over 160 km of single-mode fiber and a cascade of six erbium-doped fiber amplifiers (EDFAs) and five wavelength division multiplexed (WDM) cross-connects.
