AP

C (Angled Physical Contact): 8° angle ferrule, very low reflection, ideal for RF video and GPON networks. Color Coding: APC connectors: GreenUPC connectors: BlueFiber Compatibility: Single-mode connectors are optimized for single-mode fibers, while multimode connectors are used with multimode fibers. Many connectors, such as SC, LC, and FC, are compatible with both types.

Durability: Most connectors are rated for ≥1,000 mating cycles without performance degradation. Applications: Selection depends on network density, fiber type, and environmental conditions, such as vibration or space constraints. This table provides a comprehensive reference for selecting fiber optic connectors based on technical specifications, performance, and application requirements.
