In this paper different variations of the so-called " Tune-and-Select " (TAS) switching node for Optical Burst Switching (OBS) are investigated. Both signal degradation and burst losses limit the effective throughput of such optical burst switching nodes. These limitations are analysed for different nodes with four input/output fibres at different bit(More)
Several types of ASK multiport homodyne receivers are investigated, and the impact of the phase noise and of the shot noise on these receivers is analyzed. The simplest structure is the conventional multiport receiver with a matched filter in each branch. This structure can tolerate AvT (Av is the laser linewidth and T is the bit duration) of several(More)
Kurzfassung Im Beitrag des BMBF Verbundvorhabens TransiNet werden mögliche, auf optische Vermittlung basierende Architekturen für den IP-Transport in zukünftigen Weitverkehrsnetzen identifiziert und Bewertungskriterien für diese Architekturen aufgestellt. Dabei gilt es den zukünftigen Anforderungen, wie wachsende Anzahl von Nutzern, stetig steigendes(More)
