1-3a) Give the link a descriptive name. Press
to edit the name. Press
to continue.

STEP 2 - DEFINE LINK
2-1) Press to DEFINE LINK.
2-2) Press to CERTIFY LINK.
2-3) Scroll through the list of fiber types and highlight the link’s fiber type. Press
to select.
2-4) Enter the length of the fiber in meters. Press
to continue.
2-5) Enter the number of inline connections (connector pairs) in the link. Press
to continue.
2-6) Enter the number of inline splices in the link. Press
to continue.
2-7) Connect the light source for the wavelength shown on the display (remember: if the user is testing multi-mode fibers, the test
jumper must be wrapped 5-7 times around a mandrel). Press
or
to continue.
2-8) The settings the user just entered will appear on the display (see the example below).
SRC PWR
(shown in dBm) - actual power the light source is emitting.
100 m
(shown in dB) - attenuation value associated with the length and type of fiber the user entered.
0 CONN
(shown in dB) - attenuation value of the connectors and splices the user entered.
REF PWR
(dBm) - source power plus fiber attenuation plus connector and splice attenuation. This is the PASS / FAIL
threshold.
850nm
- wavelength that the reference is being set for.
M6
- fiber type that the reference is being set for (M6 = 62.5 µm multi-mode, M5 = 50µm multi-
mode, SI = single mode indoor, SO = single mode outdoor).
2-9) If any of the fiber characteristics were entered incorrectly, press
. The user will be asked to repeat
steps 2-3 through 2-7.
