wavelengths associated with the chosen standard (e.g. 850nm and 1300nm for TIA-568B).
TYPE
- the currently selected link’s fiber type.
dBm
- the absolute power in dBm being received by the detector. This number is compared to the reference value to
determine if the link passes or fails; i.e. if this number is less than the reference value, the link fails, or if it is greater, the link passes.
850nm
- the currently selected wavelength.
PRINT DATA
- sends the data point to the serial port in a printable format.
EDIT NAME
- repeat step 2. Use this function if you reach 00 on the auto-increment number, or if you wish to start a
new label. Using the example on the previous page, if you have completed testing the fibers in Patch Panel A, you will move on to Patch
Panel B. In this case you would EDIT NAME to say PP-B. Your auto-increment numbers would then be PP-B00 to PP-B23.
SAVE
- saves the data point in memory and returns you to the power reading display.
Press to save the data point. Repeat steps 1 and 3 for each data point you are saving for this Fiber Link.
Pressing after completing these options will return the user to the FIBER LINK MENU.
VIEW LINK CONFIG
- views the parameters that are used to calculate the link
reference value(s) when set with the Standards Wizard. The display at the right shows a typical
link configuration screen.
FIBER LINK #1 - the link name.
TIA-568B / CAN-T529 - the standard used.
LENGTH - length of the fiber link in meters.
2 CONN 0 SPLICES - number of connector pairs and splices in the link.
WAVELENGTHS: shows which wavelengths have references set. In the example,
Store Data Points, cont.
Press to continue.
3)
The screen at right shows the pertinent information about the data point you are storing.
FIBER LINK #2
- the fiber link chosen during Link Wizard.
NAME
- the fiber label chosen in step 2, with the two digit auto-increment number
appended at the end. If you are storing data for multiple wavelengths, this label applies to all
FIBER LINK #2
NAME = FBR:00
TYPE = 62.5um MM
dBm = -22.05 850nm

FIBER LINK MENU
Option 2 from the MAIN MENU takes the user to the FIBER LINK MENU.
LOAD/EDIT LINK
- edit the name and date of a link and/or load the link. See Steps 2
and 3 in the section on Fiber Certification. Loading a link that already has data stored for it will
cause the meter to resume storing where it previously left off.
CONFIGURE LINK
- set the link properties and reference values prior to storing data for that link. Remember to connect a
light source to the meter prior to setting a reference. After selecting the link to configure, there are three configuration options.
Option 1 is the same as running the Standards Wizard. Consult the section on Fiber Certification for instructions.
Option 2 allows the user to set a Manual Reference for each wavelength. This reference can be set one of two ways:
LINK BUDGET - the user is prompted to enter the maximum amount of loss (in dB) that the link is allowed to lose.
This number is then added to the light source power to arrive at the reference value.
MANUAL REF - the user is prompted to enter the reference value (in dBm) manually.
Option 3 allows the user to ZERO out the light source; i.e. set the light source power as the reference value.
NOTE: options 2 and 3 should only be used if the user has a firm grasp on how to calculate link budgets and
manual references.
