5.Operations
1. Starting up, when clean the end face of fiber, connect the interface of OTDR, make the fiber and
instrument correctly connect
2. Press ENT setting parameter; pulse width choose auto. Continuous press ENT confirm and Exit parameter
setting or continuous press◄exit ; Press SCAN start to test and get the results. The theoretical value of
refractive index is 1.4677 at 1550nm. The pulse width is set according to the length of the measuring
fiber. Small the pulse width, short the measurement distance, if cannot confirm the fiber length，can
use 100ns,then choose the pulse width according to the measurement result curve; if short distance can
choose<500m, if long distance choose<40km.
The greater the gain, the stronger the signal that can be measured.

6. Curve Analysis
Users could check the state of the fiber through analyzing the testing curve.
(1)(2)(3) Connect point of the fiber.
(4) Fiber end-face.
7. iLOM(Event Map)
The function can be tested automatically by one key, and the information of the length of the link,
the type of event point and the position of breakpoint can be displayed in a graphical form. The result is
easy is clear and easy to understand

8. OPM
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 270/3301k/2kHz frequency
optical signal.
9. VFL Function
Connect fiber to VFL port, select VFL in menu, then you could see optical light(650nm) in breakpoint or fiber
end-face.
Note: Do not see the light directly with your eyes! It is harmful to your eyes.

11. Data Saving
Press ENT button to save the testing data after testing. The ENT button is used to SAVE, READ and EXIT.
MINI OTDR could save more than 500pcs data.
12. Data Processing
1. Copy JWMINI OTDR TRACE file to your computer (files will be provided with testers or users could contact
seller for the file). Click USB driver.exe and install USB driver software.
2. After installing the driver software, connect the tester to computer with USB, click MINI OTDR.exe in the
file and then the tester will be ready.
