Purpose and user guidance

This chapter describes the commissioning of the CU1521-0020 with SFP modules. The structure deliberately follows the practical process: first define the operating mode and topology, then select the SFP, check the thermal and optical boundary conditions, set up the device, put the connection into operation and only then look at the diagnostics for ongoing operation.

Note Each step of the brief commissioning refers to a subsequent chapter in which the respective point is explained in technical terms. This allows you to work through the checklist and jump directly to the appropriate explanatory chapter if required.
