The FOA Reference For Fiber Optics
The OTDR measures distance and loss at an event - a connector or splice - between the two markers but calculates the best fit line between the two points using the "least squares" method to reduce noise.

In these situations, Real-time test mode can be used but users should ensure span loss is acquired using 2-Pt LSA settings to normalize loses across the span as opposed to point-to-point change.

Splice Loss by Two Point Method The OTDR measures distance to the event and loss at an event - a connector or splice - between the two markers. To measure splice loss, move the two markers close
Understanding Optical Time Domain Reflectometry
Bidirectional analysis is used to minimize possible mismatches by measuring the splice loss in both directions and averaging the result to obtain the true splice loss.
