Recalculate Circuit Length

To avoid the situation in which deleting a fiber cable without first disconnecting the cable results in the associated circuit not updating its Circuit Length, you can use the ReCalc button in Circuit Manager.

IMPORTANT: Regarding the circuit length, the application first looks for the fiber optic cable field that has the SEGMENTGLASSLENGTH field model name. This is the most accurate length method. If that model name is not found, the application then looks for the field with the SEGMENTLENGTH field model name. If that model name is not found, the application uses the Shape.Length from the features themselves. Finally, the application also looks for the POINTLENGTH field model name for point features along the circuit path.

After updating entries in Connection Manager, the Circuit Manager button on the Fiber Manager toolbar changes appearance: .

Based on those updated entries in Connection Manager, in Circuit Manager you can select <show recalc circuits only> from the Circuit Type drop-down to show only those circuits that need recalculated.

Highlight a circuit from the list and click ReCalc.

If you happen to end an edit session without updating any circuits in the Circuit Type list, you receive a warning.

If you save and return later, or you save and post the changes, you won’t see the updated circuits in the Circuit Type list. Therefore, you can choose to save the updated circuits to a file so you can recalculate lengths at a different time.
