Abstract

Ein bekannter Multi-Kanal-Demultiplexer für eine Datenrate von 40 Gbit/s auf der Basis eines elektroabsorbierenden Modulators nutzt dessen Bidirektionalität, um gleichzeitig zwei Datenkanäle demultiplexen zu können. s on the basis of an electroabsorption modulator uses its bidirectionality, a known multi-channel demultiplexer for a data rate of 40 Gbit / in to demultiplex two data channels simultaneously. Auftretende Reflexionssignale können jedoch zu Beeinflussungen führen. However occurring reflection signals can cause interference. Der erfindungsgemäße Multi-Kanal-Demultiplexer (MKD) nutzt den unidirektionalen Weg durch den optischen Schalter (OS, EAM) und unterscheidet zwei zu entschachtelnde Datenkanäle (A/B; C/D) durch ihren Polarisationszustand. The inventive multi-channel demultiplexer (MKD) uses the unidirectional path through the optical switch (OS, EAM) and two different data channels to be deinterleaved (A / B C / D) by their polarization state. Dazu wird ein doppelbrechendes Element (DBE) verwendet, das zwei orthogonal polarisierte Datensignale erzeugt. For this purpose a birefringent element (DBE) is used that produces two orthogonally polarized data signals. Diese werden im doppelbrechenden Element (DBE, HiBi-F) bezüglich der zu entschachtelnden Datenkanäle (A/B; C/D) zeitlich übereinandergeschoben und anschließend auf das Schaltfenster des optischen Schalters (OS, EAM) synchronisiert. These are in the birefringent element (DBE, HiBi F) with respect to the deinterleaved data to channels (A / B C / D) in time over each other and then the switching window of the optical switch (OS, EAM) synchronized. Vier Datenkanäle (A, B, C, D) können gleichzeitig gedemultiplext werden, wenn beide Durchlaufrichtungen durch den optischen Schalter (OS, EAM) und die Polarisation gleichzeitig genutzt werden, wobei alle vier Datenkanäle (A, B, C, D) zeitlich übereinandergeschoben und auf das Schaltfenster synchronisiert werden. Four data channels (A, B, C, D) can be simultaneously demultiplexed when both pass directions are used by the optical switch (OS, EAM) and the polarization simultaneously, where all four data channels (A, B, C, D) pushed over one another in time and are synchronized to the switching window. Durch die Nutzung von vier eindeutig unterscheidbaren Datensignalen im optischen Schalter (OS, EAM) kann auch gleichzeitig eine Datentaktrückgewinnung bespielsweise nach dem differentiellen Prinzip erfolgen. By using four clearly distinct data signals in the optical switch (OS, EAM) a data clock recovery can take place recordable, according to the differential principle simultaneously. Durch eine Kaskadierung können entsprechnd viele Datenkanäle auch bei vorgegebener höchster Datentaktrate gleichzeitig ... By cascading many data channels can entsprechnd same even with a predetermined highest data clock rate ...
