1. Overview
Sun Telecom’s SUN-OPM80 series optical power meter is a newly
developed product to meet the requirement of the market. It intergrades the
handheld optical power meter and the intelligent optical power meter in one
unit.
It can be used for the absolute optical power measurement and relative
optical loss measurement of the link loss in dB.
This power meter with compact size, friendly operation interface, broad
power measurement range, high precision performance and brand-new user
automatic calibration function and high in application makes it an ideal tool
for optical fiber network.

5. Operation and Notes
1.1. ON/OFF
1) Press the On/Off key for a few seconds to turn on the unit
2) Press the On/Off key for a few seconds to turn off the unit
1.2. Absolute power measurement
1) Turn on the Power Meter
2) Press the λ key to switch between the wavelengths. The default
wavelength is 1310nm.
3) Connect the light to be measured, and then result will be displayed on
the LCD screen, including Linear and nonlinear value.
1.3. Relative power measurement.
1) Select the wavelength to be measured.
2) Under “Absolute power measurement mode”, connect to the light to be
tested.
3) Press dB key, then current power value is stored as a reference value in
dB unit. At the same time it also display the current absolute power
value and current relative value is 0dB.
4) Connect to another beam of light to be tested, display the current
relative power value and absolute power value under tested..
1.4. Special function
It has 3 kinds of working mode:
1) Factory Mode
2) User Mode
3) Working Mode
1.1.1. Factory Mode: This mode is responsible for the test and calibration
1.1.2. User Mode: Press the “λ + Light” key synchronously, and then enter
the User mode. Numeral "1" will be displayed on the top right corner.
Press the “λ + Light” key synchronously once again, it exit from the
User mode and enter the Working mode. Numeral "0" will be

Appendix:
Optical fiber loss measurement
Step 1 Optical Reference Level
Turn on optical power meter and press the λ key to select the
wavelength.
Turn on optical light source (emitting source) and select the wavelength.
Wait for 1-2 minutes until it stabilized.
Select a piece of patch cords, which is used to connect with the light
source; we call it emitting patch cords. Cleaning connector of the patch
cords. The fiber of the emitting source patch cords must be the same
fiber type as the fiber under test.
Connect the light source (emitting source) with the Handheld Power
Meter through the emitting source patch cords
Handheld Power Meter gets the power measurement value.

This value should be close to the one that light source (emitting source)
set. If it has wide disparity, please make sure the fiber connection is
clean properly or replace another jumper.
Press the dB key; the reading 0.00dB will be displayed on the screen.
The tested power values will be set to the reference value.
Step 2 Optical Loss Measurement
Keep the emitting source patch cords connection with the light source
(emitting source).
Connect the Handheld Power Meter and light source (emitting source)
to the optical fiber link respectively.
Notes: cleaning all the connectors’ end-surface including all the necessary
optical adaptors. The reading in dB unit displayed on the screen is the tested
optical fiber link loss.(also display the current absolute optical power value in
dBm unit).
6. Maintenance
1) It is important to keep all optical connectors and surfaces free from oil,
dirt or other contamination to ensure proper operation.
2) Keep using one type of adapter to avoid excess loss from different
connectors.
3) Please use dust-proof cap for protection to avoid being scratched or
contaminated when Handheld Power Meter not in operation.
4) Light interface is sensitive, please carefully plug in and pull out the
connectors.
5) Please use clean cotton to clean the sensor surface, clean it in
clockwise direction carefully.
6) If does not need to use for a long time, please take out the battery.
