SAFETY INFORMATION
WARNING: Never look directly into optical outputs or a fiber while the equipment is
on. Invisible and visible laser beams may damage your eyes.
Do not short-circuit the AC adapter/charger terminal and the batteries.
Excessive electrical current may cause personal injury due to fumes,
electric shock, or equipment damage.
Connect the AC power cord to the equipment and wall socket properly.
When you insert the AC plug, make sure there is no dust or dirt on the
terminals and both plugs are fully seated.
WARNING: If the AC plug is not connected properly, fuming, electric shock, or
equipment damage might occur and may result in personal injury.
Do not operate the equipment near hot objects, in hot environments, in
dusty/humid atmospheres, or when condensation is present on the
equipment. This may cause electric shock, product malfunction, or poor
performance.

Chapter 2: Overview
2. Overview
2.1 Introduction
The Basic Single Mode Light Source and the Basic Multimode Light Source are
miniature dual-wavelength laser sources. Use a light source to test segments of
single-mode or multimode optical fiber. The light sources also work with our
Optical Power Meter (FOPM-100) to measure optical fiber loss. A single output
connector provides stable power at dual wavelengths. The compact unit operates
in either continuous wave (CW) mode or modulated mode. A low-battery indica-
tor reminds you to recharge the battery when needed.
2.2 What’s Included
Your package should include the following items. If anything is missing or
damaged, contact Black Box Technical Support at 724-746-5500.
• Main unit
• Carrying case
• Small Phillips screwdriver
• AC adapter
• FC/PC interchangeable connectors (SC/PC and ST/PC available)
• This user’s guide on CD-ROM
• A printed Quick Start Guide
• Quality check report
2.3 Features
• Small, compact unit is lightweight and is easy to carry
• Single output provides continuous wave (CW) mode or modulated mode.
• Has backlighting, rechargeable battery, LCD screen, and auto-off.

3. Operation
3.1 Battery Indicator
A battery indicator on the screen shows the remaining charge. See Figures 3-1
and 3-2. Table 3-1 describes the LED status.
Figure 3-1. Battery indicator full.
Figure 3-2. Battery indicator empty.
Table 3-1. Battery indicator status.
Status Icon Description
Full Battery at 100% capacity
2 Bars Battery at 50–75% capacity
1 Bar Battery at 25–50% capacity
Empty Battery at 0–25% capacity
The battery icon flashes when the power is
almost depleted. Connect the AC adapter to
the light source to recharge the battery.
NOTES: To replace the batteries, use a screwdriver to remove the battery plate on
the back of the light source. Contact Black Box Technical Support for a
replacement battery.
The AC indicator is not displayed when power is supplied by battery.
To eliminate the possibility of acid leakage, remove the battery if you
won’t use the light source for an extended time.

Chapter 3: Operation
3.2 AC Operation
If you will use the light source at one location, for example, in a laboratory or test
department, you can use the AC adapter to power it instead of batteries. Plug the
AC adapter’s output cable into the DC input jack on the light source’s bottom
side. When the AC adapter is plugged in, the AC indicator on the LCD will be dis-
played. See Figure 3-3.
Figure 3-3. AC adapter indicator.
NOTES: Power is supplied by the AC adapter when plugged in even if the battery
is installed. The battery indicator does not display on the screen.
Make sure that the operating voltage is within the range of the local AC
voltage. For example, input: AC 100-240 V, 50-60 Hz.

4.2 Turning the Light Source On and Off
1. Press the key for less than two seconds. The light source powers on
and you see the screen shown in Figure 4-4.
Figure 4-4. Screen that appears when the light source powers on.
2. Press the key briefly again. The light source powers off.
3. The light source powers off automatically if you do not press a key within
10 minutes. To turn off the auto-off function, press the key for more
than two seconds when turning on the light source to deactivate the auto-off
function and the indicator will disappear on the LCD.
4.3 Switching the Wavelength
Press the key repeatedly until the desired wavelength displays. Select from
two possible wavelengths: 850 and 1300 nm (FOLS-MM-100) or 1310 and 1550
nm (FOLS-SM-100). See Figure 4-5.

4.6 Connecting to the Optical Power Meter
When connected to our Optical Power Meter (FOPM-100), the light source
accurately measures the fiber loss at distances up to 300 kilometers at 1300 nm.
On-the-spot measurements will differ with the working wavelength, fiber
attenuation, and the testing environment.

5. Maintenance
Disconnect the AC adapter/charger and replace the protective dust cap once you
finish using it.
Clean the connector and the instrument when they get dirty from use. We
recommend using optical cleaning pads and anhydrous alcohol. Be careful
not to get liquid inside the instrument.
For measurement accuracy, calibrate the light source once a year.
