Introduction
The Optical Power Meter is a high accuracy optical power
measurement tool. It tests dynamic range of optical power
from +3 to –60dBm with six calibrated wavelengths:
850nm, 1300nm, 1310nm, 1490nm, 1550nm and 1625nm.
With Hobbes Optical Power Meter, it displays a pass or fail
result according to the threshold the user has defined. It
also has the capability to identify modulate signals (270Hz,
1kHz, 2kHz) simultaneously by the power source for
identification purposes. For fast and easy operation in
testing the corresponding wavelengths, we recommend
the Hobbes optical light source (OPTIsource) as a
complete instrument in auto-identifying wavelength of
optical power source.
It utilizes an InGaAs detector for an improved sensitivity
and temperature stability. It also has the capacity to record
up to 1000 test data that is up-loadable to a PC via USB
connection for easy and convenient report purposes.

Instructions for operation
1.Turn on/off the unit
Turn the unit on:
Press and hold the “On/Off” button for a few seconds,
the unit will display all the screen contents on the LCD
until button is released. The unit then enters the TEST
MODE automatically.
When power is on, press “On/Off” button to activate/
deactivate auto power off function. (Note: auto off time
is 5 minutes)
When power is on, press “On/Off” button for a few seconds
to turn off the unit.

2. Backlight function
When power is on, press “Mode” button for a few seconds
to activate/deactivate LCD backlight.
3. Mode selection
When Power is on, press “Mode” button to enter the mode
selection menu. 6 Selection Modes: TEST MODE, RECORD
MODE, BROWSE MODE, SET MODE, ZERO MODE, and
LIMIT MODE.
Press the “Mode” button to switch between mode options
and press the “Enter” to select the corresponding mode.
3-1 TEST MODE
TEST Mode is set by default when powering the unit on. In
TEST MODE, the meter receives fiber power source, tests
and displays power value, and a pass/fail indicator by user-
defined threshold.

How to measure in db power value
Step 1: First, set power reference value (REF):
(Press and hold “dBm/W” button for a few seconds to set
the current power values as power reference value)

11

Step 2: Formula and Example are as follow:
Formula:
The current value (in dBm) –REF = the current value (in dB)
Example:
REF= –46.97dBm, the current value (in dB)= –13.79
Then the current value (in dBm) = (–46.97dBm) + (–13.79dB)
= –60.76dBm
Switch power measure of three types to power value.
Press “dBm/W” button to switch power measure (dB, dBm,
or Watt)
Change wavelength
Press “button” to change wavelength at 850nm, 1300nm,
1310nm, 1490nm, 1550nm and 1625nm.
Reference value setting
Press “dBm/W” button for a few seconds to set the current
power values as power reference value (in dBm measure)

Saving data in TEST MODE
Step 1: Press “Enter” button for a few seconds to save the
current test result.
Step 2: User can press “Up” and “Down” button for setting
the fiber ID. Otherwise, the unit prepares the fiber ID
according to 1 step increment. The fiber ID is from 1 to 999.
3-2 RECORD MODE
By using SMARTFiber Pro RECORD MODE function, user can
test the stability of LD light source in a period of time. In
RECORD MODE, the unit tests and restores fiber power value
automatically in a period of time. The recording test result
from record mode is only viewable in SMARTFiber Pro
application after recording data upload to the PC, it is not
available in browse mode. Once the record set up is finished,
device will test and record power value in set up test time.
The default test time is 15 minutes, and default sample
frequency is 5 seconds.
