With the optical ROADM Spectrum Analyzer OSA-500R (RS), all possibilities are offered to set and measure current networks on the optical layer.
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.
