Design of a 10-Gb/s burst-mode optical packet receiver module and its demonstration in a WDM optical switching network
ABSTRACT A 10-Gb/s burst-mode optical packet receiver module was fabricated. Its sensitivity was -24.8 dBm. Its sensitivity penalty due to packet-arrival timing jitter was less than 1.5 dB in arbitrary relative phase, and its total sensitivity penalty due to power fluctuation and packet-arrival timing jitter was less than 2.9 dB when the magnitude of packet-by-packet power fluctuation was 9 dB. We experimentally confirmed that our burst-mode optical packet receiver did not cause a penalty for wavelength division multiplexed (WDM) optical switching using the wavelength channel selector module.

ABSTRACT: This article presents an operators' view of the evolution towards broadband optical access networks. First, we describe a possible evolution of the optical access solution for point-to-point and point-to-multipoint architectures. Subsequently, currently available optical access solutions are evaluated and compared. Finally, we consider regulatory issues inside and outside Europe, and conclude by offering a recommendation with respect to regulationIEEE Communications Magazine 09/2006; · 3.79 Impact Factor

ABSTRACT: We demonstrate an all-optical retime, reshape, reamplify (3R) burst-mode receiver (BMR) operating error-free with a 40-Gb/s variable-length asynchronous optical data packets that exhibit up to 9-dB packet-to-packet power variation. The circuit is completely based upon hybrid integrated Mach-Zehnder interferometric (MZI) switches as it employs four cascaded MZIs, each one performing a different functionality. The 3R burst-mode reception is achieved with the combination of two discrete all-optical subsystems. A reshape, reamplify BMR employing a single MZI is used first to perform power equalization of the incoming bursts and provide error-free data reception. This novel approach is experimentally demonstrated to operate error-free, even for a 9-dB dynamic range of power variation between bursty data packets and for a wide range of average input power. The obtained power-equalized data packets are then fed into a 3R regenerator to improve the signal quality by reducing the phase and amplitude jitter of the incoming data. This packet-mode 3R regenerator employs three MZIs that perform wavelength conversion, clock extraction, and data regeneration for every packet separately and operates at 40 Gb/s, exhibiting rms timing jitter reduction from 4 ps at the input to 1 ps at the output and a power penalty improvement of 2.5 dBJournal of Lightwave Technology 02/2007; 25(1):184-192. · 2.78 Impact Factor
