Abstract :
We demonstrate a switch fabric architecture that allows multicasting and broadcasting and record fast channel access in the nanosecond range. The 10-Gb/s receiver modules are based on a heterodyne detection technique, which is tolerant to moderate wavelength drifts of the local oscillator. A gain clipped electrical amplifier is used as rectifier for bandpass signal recovery.
