FAQs

Tips

Why do I need to use 
a launch and receive 
cable? 

A launch cable allows the OTDR to settle 
down  after  the  initial  pulse  and  provides 
a  reference  cable  for  testing  the  first 
connector on the fiber under test. A receive 
cable provides a reference cable for testing 
the last connector of the fiber under test.

What is the purpose of 
the Live Mode?

With a launch cable, the Live or “real-time” 
mode may be used to quickly view many 
short  fiber  links.  It  can  also  be  used  to 
quickly “trace” short fiber link fibers.

What is the advantage 
of the Expert Auto 
Mode?

User is able to select a single 

l

 and have the 

OTDR set the other test parameters.

Can I save traces for 
viewing later?

Yes. There is a dedicated 

Save 

key. In the 

Main Menu “File Tab”, set up the location/
folder (Internal, CF, or USB) to save the file, 
the file naming format and fiber number. 
The fiber number will increment after each 
trace is saved. 

Test in feet or meters?

If you know your fiber distances in feet, it 
may be beneficial to measure distances to 
events/faults in feet. 
Fiber  loss  specifications  are  given  in 
dB/km. Therefore it is often beneficial to 
measure fibers in meters/kilometers when 
loss results are required.

Expert OTDR Setup

RANGE: Length

•  Too  Short:  you  will  not  capture  the 

entire fiber length

•  Too Long: trace will be squashed to left 

side of Screen

•  Good Range: 1.5 to 2 times length of 

actual fiber

PULSE WIDTH:

•  Too Narrow: trace disappears into noise 

floor before end of fiber is reached

•  Too Wide: events can not be resolved
•  Good Pulse Width: Events can be seen 

and trace is smooth

AVERAGES:

•  Too Few: Trace is noisy, trace floor is 

too high

•  Too Many: Trace is smooth but wastes 

time

•  Good  Number  of  Averages:  smooth
