A:
2. When no optical amplifier board is configured in the optical path and when the OPA does not work, the solution is to disable the OPA function. Note that in this case, the optical parameter-based path calculation function of the ASON cannot be provided. When you create an ASON service, deselect the Enable Optical Parameter Constraints option on the T2000.
3. You can also add a logical optical amplifier board to meet the OPA function and the optical parameter-based path calculation function of the ASON. You must be very careful and pay attention to the following two points:
4. (1) The budget of the optical power must be met.
5. (2) The reference value of the logical optical amplifier must be set manually based on the actual optical power.
