The SPEED-xWDM Series includes a variety of passive CWDM and DWDM modules with different numbers of channels. The SPEED-CWDM Series is available in five, eight, nine and 16 CWDM wavelengths per system card. The CWDM five and nine wavelengths multiplexers have a cascading port that allows them to be extended by another eight CWDM wavelengths without interruption of the running operation.Through the use of DWDM modules, up to 96 DWDM channels can be transmitted over one pair of optical fibers. For each channel, e.g. 200 Gbps application are switched - thus results in a total data rate of 19.2 Tbps per pair of optical fibers.With the help of our cascading concept it is possible to cascade eight to 40 DWDM channels without interrupting already running services.With DWDM band filters, DWDM bands with eight DWDM channels each can be interconnected with lowest signal loss at intermediate locations.The SPEED ad & drop multiplexers are available for CWDM or DWDM applications. With the use of the ad & drop multiplexers, it is possible to deduce and disengage one or more wavelengths in a fiber optic link without having to extract all wavelengths via a CWDM or DWDM module.Depending on customer requirements, we manufacture individual CWDM / DWDM modules with different wavelengths, connectors and port numbers for different housing types.The dispersion compensation module SPEED-DCM compensates the propagation time differences of the different DWDM wavelengths in optical transmission systems. It is a purely passive device which can be equipped along the link for ranges from 20 km to 200 km, depending on the requirements. The dispersion compensation is totally protocol transparent.The SPEED-SPLIT series enables live monitoring of all wavelengths via an external OSA (Optical Spectrum Analyzer) meter. For this, e.g. SPEED-SPLIT 97/03 provides 3% of the optical power and provides it for the analysis.
