| Popis: | We propose and demonstrate a transparent wavelength division multiplexing (WDM) metro ring architecture in which optics enables simultaneous provisioning of dedicated wavelengths for high-end users, while low-end users share wavelengths on "virtual rings". All wavelengths are sourced by the network and remotely modulated at customer end stations (ES) by low-cost semiconductor optical amplifiers (SOAs), which also serve as transmission amplifiers. Measured bit error rate (BER) data for three different ring configurations show negligible power penalties associated with upstream transmission around a 120-km 3-mode ring through as many as four cascaded SOA/modulators. Preliminary tests indicate that the SOAs are suitable modulators for packet transmission over the network. |
