Insertion Loss (IL): Measures the reduction in optical power as light passes through the patch cord. Typical IL values for standard patch cords range from 0.3 dB to 0.5 dB, while low-loss cords can achieve 0.15 dB to 0.2 dB. IL directly affects signal strength and link budget in optical networks . Return Loss (RL): Quantifies the amount of light reflected back toward the source. High RL values indicate minimal reflection, which is critical for high-speed and sensitive applications. APC connectors are often used in long-haul or GPON/FTTH networks to minimize back reflection . Polarity Testing: Ensures that transmit (Tx) and receive (Rx) channels are correctly aligned, which is especially important for multi-fiber assemblies like MPO/MTP systems . Endface Inspection and 3D Interferometry: Connector endfaces are examined for scratches, pits, contamination, and polish defects. 3D interferometers measure curvature radius, apex offset, and fiber height to confirm compliance with standards such as IEC 61754, GR-326, and TIA/EIA-568 .
