In current networks, optical wavelengths are no longer transmitted only between two points. Wavelengths are now switched or routed on the optical layer (CWDM / DWDM) according to the requirements.
In such networks, wavelength-selective components (ROADM) are used for coupling / decoupling wavelengths. Here, a spectral measurement of the signals is essential. With the optical ROADM Spectrum Analyzer OSA-500R (RS), all possibilities are offered to set and measure current networks on the optical layer. If wavelengths are taken out of a network and possibly transferred back into another network of DWDM channels, the in-band OSNR measurement comes into play. This measurement allows to view a single channel. In this channel, the influences of the adjacent channels can now be measured in order to clearly illustrate the in-band influence. From the used channel grid a channel can be extracted and analyzed individually.
Further optional testing options include a software-based "fixed-analyzer" PMD measurement and a test application for signal sources such as laser diodes, LEDs and optical amplifiers. These modules fit into the MTS8000 and MTS8000E (V2) platforms.
