to highlight the link to use. Press to edit the name and the testing date of the selected link.

EDIT LINK

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

1-3b) Enter the date of the test. Press to enter the date. Press to continue.

1-3c) When the name and date have been entered, press to return to the STORED LINKS menu.

1-4) Press to load the selected link. The user will be returned to the MAIN MENU.

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.
