OTDR-File Save
Press (Save) key to save �ile after test
complete, pop up the keyboard, enter the name of
the �ile, and press Enter to save the �ile. If the
automatic save (otdr) function is turned on in
"System Settings", it will be saved automatically
after the test complete without manual operation.
Auto-save function
Enter the system settings, open the auto-saving
function, the instrument will automatically save the
test �iles after the average or auto-test.

information of the length of the link,
the type of event point and the position

graphical form. The result is clear and
easy to understand.
This function is used to test the power of
optical signal and insertion loss of
various devices and optoelectronic
components. It can identify and measure
the frequency of 270/330/1k/2kHz
frequency optical signal.

Visible red light (650 nm) is injected into the
optical �iber, and the position of the optical
�iber fault point can be judged conveniently
and accurately by observing the leakage
position on the measured �iber. It is suitable
for the detection of bare optical �ibers,
jumpers and other high loss sections caused
by near-end faults and micro-bending of
optical �ibers and cables which can leak red
light.
Avoid looking directly at the laser output port.
Laser can cause damage to human retina.

The wavelength of stabilized laser source is
the same as OTDR wavelength. It is used to
measure the parameters of telecommunica-
tion, CATV, LAN cable, insertion loss, isola-
tion loss and echo loss of optical passive
devices, and wavelength responsiveness of
detectors.
There are �ive modes of light source: CW,
270 Hz, 330 Hz, 1 kHz and 2 kHz.
