  OTDR Module

Optical Return Loss

ORL calculation:  
1) ORL between marker line A and marker line B.
2) Total ORL between start point of fiber span and the end point of fiber span.

(Only the ORL of the single mode fiber can be calculated. In real-time mode, the 
value of the ORL may not be always accurate.)

Note: in real-time mode, the value of the reflectance may not be always ac-
curate.
