The network architecture is expected to provide sufficient network fault tolerance, redundancy, reconfigurability, scalability, and reliability consistent with system fault detection, fault isolation, and false alarm rate expectations. Highly accurate and time efficient fault detection and isolation in the mission environment is needed to efficiently maintain aircraft operational readiness.
The specific fiber optic network architecture should facilitate both preventive and corrective fleet maintenance. An example of preventative maintenance includes the ability to readily inspect and clean WRA and cable plant connectors.
Examples of corrective maintenance include: 1) the ability to repair a faulty connector terminus pin or socket in the aircraft cable harness, 2) the ability to efficiently remove and replace a faulty aircraft WRA, and 3) the ability to repair or replace a broken fiber in the aircraft cable plant.
