Abstract
We have already proposed the wavelength conversion method which is composed of an optical Single Side-Band (SSB) modulator and Mach-Zehnder interferometer (MZI). The optical signal is converted by using basic part of this wavelength converter with 50GHz frequency conversion. We have observed the converted frequency optical spectra, eye diagrams and bit error-rate. The converted optical signals are detected without bit error, but the received optical power at 10-9 error rate is degraded by the conversion because of the optical amplifier noise and filtering by MZI. The wavelengths of 10Gbit/s optical packets are converted by this basic unit. The converted packets are routed using AWG de-multiplexer. The carrier components are around 15dB lower compared with signal. The switching time was 200ns which is correspond to the delay of the loop.
