The SPEED-WDM Series includes a variety of passive CWDM and DWDM modules with different numbers of channels. The SPEED-CWDM Series is available in 5, 8, 9 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 64 or 96 DWDM channels can be transmitted over one fiber optic. For each channel, e.g. 400 Gbps application are switched - thus results in a total data rate of 25.6 Tbps per pair fiber optic.
With the help of our cascading concept it is possible to cascade 8 to 40 DWDM channels without interrupting already running services.
With DWDM band filters, DWDM bands with 8 DWDM channels each can be interconnected with lowest signal loss at intermediate locations.
The SPEED-Add&Drop multiplexers are available for CWDM or DWDM applications. Using Add&Drop multiplexers, it is possible to couple and decouple one or more wavelengths in a fiber in a dedicated manner without having to use a CWDM or DWDM multiplexer to extract all wavelengths.
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.
