The placement of amplifiers, attenuators, and dispersion compensating elements (DCMs) has to be done
to keep the link performance, optical powers, accumulated dispersion, and OSNR within the equipment capacity
Besides, design engineering rules impose extra limitations on system performance.
The Design Assistant mode simplifies and accelerates the tedious routine of manual equipment configuration, especially of
complex WDM networks. It shows problem points, lists equipment that can be inserted, and simplifies configuration process.
The compensation process includes several steps:
Validation of the initial configuration (Do all channels meet receiver operating ranges? Are amplifiers and
Placement of amplifiers and DCMs taking into account input signal metrics, design rules constraints, and equipment operating ranges
Placement of attenuating pads to equalize added and express channels or to attenuate dropped channels to meet receiver limits
Evaluation of system performance during the design process
Placement of amplifiers and attenuators at ring break points in order to finalize manual link loss compensation in the design with
The system design workflow also includes detailed performance analysis and report generation using the built–in
functionality of VPIlinkConfigurator or customized reporting tools realized via API.
