5.2.2 Averaging Mode and Real-Time Mode
Real-Time Mode:
The OTDR will undertake a real-time measurement for the connector or exterior fiber
and continually update the trace. While in “Real-Time Mode,” unless the user stops measuring, the OTDR
will continue measuring.
Averaging Mode:
Under “Averaging Mode,” the OTDR will average the data within the measurement
time, which is set by the user. At the end of the designated measurement time, the OTDR will
automatically stop measuring and display the final results of the trace.
Note:
As a general rule, it is suggested that the user leave the OTDR in “Averaging” mode.
5.2.3 In-Service Mode and Normal Mode
In-Service Mode:
Measures live fiber, using 1625nm to test.
This mode does not affect the normal operational wavelength in the fiber under test.
Normal Mode:
Uses wavelengths other than 1625nm (such as 1310nm, 1490nm, 1550nm and etc.).
Before testing, please make sure there is no light present in the fiber under test.
Caution
When using the “In-Service” mode, the fiber must be connected to the right port of 1625nm. If it is
connected to other port, it may result in an imprecise test trace or even permanent damage to the OTDR.
Note:
●
The OTDR can only be in the “In-Service Mode” when the 1625nm wavelength is being used.
●
When the OTDR is in “In-Service Mode,” other wavelengths (such as 1310nm, 1490nm,1550nm etc.)
are not available
●
Both “In-Service” and “Normal Mode” can be used alternatively, but some modes are not available
under certain conditions.
