The meaning of items indicated in the following table:
Test Wave
Test Wavelength of OTDR, including 1310nm,1550nm and
1310nm&1550nm 3 kinds of mode.
Test Mode
Auto Mode: AD5000 will set best parameters for current test
Manual Mode: set parameters manually.
Test Time
Under averaging test mode(TEST),longer test time has better SNR
(Signal Noise Ratio) but takes more time.
Test Range
Test distance of OTDR .adjust only in manual mode,in auto mode this
item set as "Auto".
Pulse Width
Wider pulse has stronger backward signal, OTDR has longer detecting
distance but wide pulse width will cause the saturation of backward
signal, make blind area bigger.so the selection of pulse width has close
relationship with the length of fiber. Long fiber has wide pulse width..
pulse width could only modified in "Manual"mode.
Resolution
Sampling resolution of test, High resolution has more sample point and
high precision,but take more memory space.
Unit
Unit of test result,including km/kfeet/miles.
