1-channel add&drop C/DWDM multiplexer
The SPEED-AD-xWDM is a compact cost-effective optimised add&drop multiplexer for CWDM and DWDM applications. A dedicated wavelength can be dropped out of a fibre optic link that parallel transmits multiple C/DWDM wavelengths by using an add&drop multiplexer. All incoming wavelengths are received at one of the both line ports in such a daisy-chain structure. The required wavelength/application are dropped by the so-called “drop”-client port. This in the further course unused wavelength can be connected with a new application by the so called “add”-port. The new application and the remaining, non-dropped wavelengths are conjoined transmitted to the next site by using the second line port.
Multiple use of C/DWDM wavelengths
Add&drop C/DWDM in a ring: DSLAM backhauling and shift-in
Add/drop multiplexers are often used in ring structures requiring longer distances as significantly improved attenuation values can be achieved compared to standard CWDM and DWDM multiplexers. A ring structure enables to realize a backup scenario in addition to an actual transmission. This backup scenario assures the data transmission – even after a fibre break between two sites.
