Exfo FIP-400-P-DUAL – fiber inspection probe

The EXFO FIP-400-P-DUAL is a dual-magnification fiber inspection probe engineered for high-resolution end-face examination of fiber optic connectors. It delivers theoretical resolution below 2 µm with detection capability down to 1 µm, enabling identification of scratches, contamination, and surface defects across MPO/MTP and single-fiber connector types without adapter reconfiguration. The probe features adjustable dual magnification with selectable fields of view: low magnification at 625 µm × 464 µm and high magnification at 412 µm × 306 µm.

Coaxial blue LED illumination ensures consistent lighting geometry for accurate defect assessment.
