Mode conditioner and portable high-resolution reflectometer for maintenance and diagnostics of single and multi-mode avionic fiber networks

With millimeter spatial resolution, 500 meter maximum device length, −130 dB sensitivity and near-zero dead-zone, the portable OBR provides precise location and quantification of links faults. Further, when combined with novel, low-loss mode conditioners, the OBR supports various single mode and multi-mode fiber platforms in a single system, reducing size, weight, complexity and cost of inspection and maintenance test equipment.
