Required inputs
Node pair, measured span, patch and splice loss, platform software, protection path and field temperature.
Solution
ISP Transport And Access
ISP access, aggregation and transport optical links with route and certificate boundaries.
Review This TopologyDesign constraint
Optical budget, dispersion or amplification context, alarm thresholds and certificate requirements by destination.
Acceptance output
Route budget, receive-power baseline, protection switch test, alarm capture and field-spare identification.
ISP Transport And Access
Treat access, aggregation and transport spans as different engineering cases, with route loss and field replacement rules attached to each model.

Plan and validate the route
Optical budget, dispersion or amplification context, alarm thresholds and certificate requirements by destination.
Record endpoints
Node pair, measured span, patch and splice loss, platform software, protection path and field temperature.
Test the constraint
Optical budget, dispersion or amplification context, alarm thresholds and certificate requirements by destination.
Prevent the likely failure
Nominal reach is not a field acceptance test; unrecorded loss or alarm limits can make a link unstable after handoff.
Define acceptance
Route budget, receive-power baseline, protection switch test, alarm capture and field-spare identification.
