Fiber assignment, reservation and faults
Manage fiber usage classes, reservations and fault markers alongside saved connections.

What does assignment show?
Fiber strand assignment counts fibers by usage class. A class has a name, colour and technical purpose keys. Templates apply to cables according to cable class, fiber count or a selected cable list; they allocate fiber ranges to classes.
These are physical fiber counts. For building, endpoint or user provision, see Addresses and buildings and Quantities and network occupancy.
| Indicator | Meaning |
|---|---|
| Connected | Fibers with a saved connection. |
| Unconnected | Fibers without a saved connection. |
| Available | Unconnected fibers that are neither reserved, faulty nor unresolved. |
| Reservation | Fibers set aside for use. |
| Faulty | Fibers marked as faulty by a user. |
| Unassigned | Fibers found to have no active usage class. |
| Could not assess (conflict) | Fibers whose effective class cannot be resolved because templates conflict. |
If a cable matches multiple templates, fibers without an exception become unresolved. New connections or reservations cannot be saved for those fibers. Projects without templates do not check classes; reservation and fault checks still apply.
Change a fiber record
- Select the cable on the map.
- Select the relevant fiber number under Fiber strand assignment in its card.
- If needed, select Reservation (unavailable for connection) or Faulty, and enter a Note.
- Organisation administrators can change Class exception. By template uses the template class; Unassigned (disable template) removes that class from this fiber.
- Enter a Reason when changing the class exception.
- Select Save.
On a fiber, R denotes reservation, A a fault and İ a class exception. The ring colour is the effective assignment class; it does not have the same meaning as the physical fiber colour.
A faulty fiber cannot receive a new connection. A reserved fiber may only belong to a connected chain composed entirely of reserved fibers; no unreserved fiber or equipment port may remain in that chain. Reserving or releasing just one fiber in a connected chain may therefore be rejected. Do not interpret a reserved chain preserved during cable splitting as available fiber provision.
Manage assignment rules
An organisation administrator changes classes, templates and the violation policy.
- Select Edit rules in Fiber strand assignment.
- Define the usage class with Class, then cable criteria and Fiber ranges with Template.
- Prepare each change with Add to draft.
- Select Preview and inspect affected records, conflicts and warnings.
- If the result is appropriate, select Approve to save.
Reject (violation is not recorded) blocks a write that would violate a class rule. Warn (violation is recorded and reported) accepts the record and reports the violation. Selecting a warning policy does not remove mandatory reservation, fault or unresolved-assignment checks.
Components with stale data lists class violations or unassessable states within a connected group of fibers and equipment. If another session has changed a record, use Load current values and review your change again. Other project rules are explained in Project settings.
