ARRANGEMENT AND METHOD RELATING TO OPTICAL TRANSMISSION |
摘要 |
The present invention relates to an arrangement (10) and a method respectively for wavelength dependent routing of optical signals including a number of wavelengths. The arrangement comprises an optical Add-Drop multiplexing arrangement with input and output waveguides which comprises a routing device (5) with in- and outputs. The routing device (5) includes splitting means (11) with a number of inputs and combining means (12) with a number of outputs. One of said inputs (13N) and outputs (14N) respectively are used for a multi wavelength input whereas another input (13N-1) and another output (14N-1) respectively are used for an add/drop wavelength respectively whereas the other inputs and outputs (131-13N-2; 141-14N-2) are used for looping back of the remaining wavelengths. Between the splitting and combining means a number of branch waveguides are arranged and both wavelength demultiplexing/multiplexing and switching is provided for by the routing device (5).
