SSF TL-SSF-TESTK-1 User manual

Your power meter and light source units will be used to measure loss in dB of the power transmitted into the cable by the light source
versus power measured on the receiver end by the power meter. Loss testing is done at wavelengths for the ber in use, typically
850nm for multimode and optionally at 1300nm, while single mode is tested at 1310nm and optionally 1550nm. The measured loss
can be compared to the estimated loss for the link or “loss budget.”
This testing kit combined with the included reference cables allows for single-ended loss testing of ber optic cables. Double ending
requires additional reference cables.
For set-up, allowable loss, link budget calculations, etc., the Fiber Optic Association (FOA) is a great resource for testing guidelines.
FOA power testing instructions are included with your kit and should be reviewed prior to using this equipment. Information on the
two noted tests above can be found via the FOA at www.thefoa.org, including ber optic testing methods and standards.
**AAA (1.5 V) BATTERIES REQUIRED. BATTERIES NOT INCLUDED. INSERT 3 PER UNIT TO OPERATE.**
1. Select correct light source for ber type
being tested (SM = single mode or MM =
multimode; labeled above screen on left).
Turn on both light source (OLS) and power
meter (OPM).
Set both the OPM & OLS units to the desired
wavelength by pressing the wavelength
button on each unit.
850nm: Typical multimode testing
1310nm: Typical single mode testing
1A. Wavelength on the OLS is displayed in
the upper left corner of the screen. Set to
desired value (press wavelength key.)
KHz (lower right) will have a numeric
reading or dashed lines when the laser is on.
Dashed lines (---) indicate that the laser is in
continuous wavelength mode.
1B. Set OPM to same to same wavelength
as the OLS unit. Press the wavelength
button until desired value appears.
Note: Typically 850nm for multimode
testing and 1310nm for single mode.
*Use appropriate cables. Aqua =
multimode. Yellow = single mode.
2. On the OLS press CW button until 1.0
KHz* displays in lower right of the screen
(see step 1A image).
*Typical testing conguration for most
cables
3. On the OPM, press the “dBM/W” button
until dBM is the unit listed to the right of the
main screen read-out (see step 1B image).
4. Plug REFERENCE cable into OLS. Note: Do
not look into laser while unit is on.
SC testing: plug appropriate multimode or
single mode cable into OLS.
LC testing: Attach appropriate SC to LC
adapter, then plug MM or SM reference
cable into adapter.
Adapter: Beige = multimode
Blue = single mode

WARNING: LIGHT SOURCE LASER DOES NOT OPERATE AT VISIBLE WAVELENGTH. LIGHT IS NOT VISIBLE
WHEN LASER IS ACTIVE. TO AVOID THE RISK OF EYE DAMAGE, DO NOT LOOK AT LASER WHEN LIGHT
SOURCE IS OPERATIONAL.

5. For single-ended testing, plug in
appropriate SC cable or LC cable with SC
to LC adapters (single mode or multimode
according to the cable being tested) between
OLS and OPM.
Aqua = multimode. Yellow= single mode

6. For double-ended testing, plug in two
appropriate SC cables or two LC cables with
adapters, one into OLS and one into OPM,
with SC connectors or LC to SC adapters
into OPM and OLS ports.1
Link SC or LC ends together with
feedthrough adapter.

7.Reference OPM.2
Once cable(s) are connected between
OLS and OPM units, press and hold “REF”
button for two seconds. OPM should now
read 0dB.
7A. Single-ended Testing:
Unplug connector from power meter side
ONLY. Place feedthrough SC or LC adapter,
depending on cable being tested, on
connector.
Connect cable to be tested. The dB value that
appears center of screen (see step 7) is the
loss value.
7B. Double-ended Testing:
Unplug connector from SC or LC
feedthrough adapter. Place additional SC or
LC feedthrough adapter on connector.
Connect cable to be tested. The dB value
that appears center of screen (see step 7) is
the loss value.
1 Double-ended testing is
optional and requires additional
reference cables.
2 Performing Step 7 removes the
power loss of the “reference”
cables so that the dB loss reading
of the installed cables will not
include the loss of the reference
cable(s) utilized.
Refer to the included FOA instructions “Guide to Fiber Optics & Premises Cabling” to perform A>B and B<A
testing to properly diagnose high loss connector terminations.
For accurate testing, frequent cleaning of all connector faces being placed under test, maintaining minimal bends
and movement of reference cables, and resetting of power meter reference throughout the course of testing are
recommended.
