The penalties are calculated and presented separately from the GSNR.
They are also taken into account when optimizing trx mode and verifying
path feasibility in path_requests_run processing.
Penalties are specified in the eqpt_config file as part of trx modes.
This patch includes specifications for OpenROADM trx modes.
Penalties are defined by a list of
impairment_value/penalty_value pairs, for example:
"penalties": [
{
"chromatic_dispersion": 4e3,
"penalty_value": 0
},
{
"chromatic_dispersion": 18e3,
"penalty_value": 0.5
},
{
"pmd": 10,
"penalty_value": 0
},
{
"pmd": 30,
"penalty_value": 0.5
}
]
- Between given pairs, penalty is linearly interpolated.
- Below min and above max up_to_boundary, transmission is considered
not feasible.
This is in line with how penalties are specified in OpenROADM and
compatible with specifications from most other organizations and
vendors.
The implementation makes it easy to add other penalties (PDL, etc.) in
the future.
The input format is flexible such that it can easily be extended to
accept combined penalty entries (e.g. CD and PMD) in the future.
