Some companies have their own set of optical fiber loss parameters – such as fiber loss, connector loss and
splice loss – that they need their network to adhere to. Thus, the FiberMeter allows the user to configure two
user-definable cabling standards for the purpose of fiber certification.
These standards are defined when selecting the fiber standard during the Link Wizard process.
NOTE: one of the key parameters for defining these custom cabling standards is fiber loss (dB per kilometer).
Each custom standard supports a different range of optical losses (for up to 2 wavelengths), thus it is important
to know what the fiber loss is because this determines which user-definable standard to use.
USER DEFINED #1 supports fiber losses for up to two wavelengths from 0.01 dB to 2.55 dB per kilometer
USER DEFINED #2 supports fiber losses for up to two wavelengths from 0.1 dB to 25.5 dB per kilometer
1) Press to scroll through the list of fiber standards.
2) When the correct custom standard is highlighted, press to EDIT.
3) From the SELECT WAVELENGTHS screen, press to scroll to the
first wavelength to configure.
4) Press to select this wavelength as the first wavelength.
5) Enter the loss per kilometer in dB for 62.5/125 MM fiber in the entry field.
Decimals can be entered by holding the key to scroll through the
special characters. If it is not necessary to enter a value, leave the entry
field blank.
6) Press to continue. Repeat Steps 5 & 6 for the remaining fiber types.
7) Enter the loss per connection in dB, then press to continue.
8) Enter the loss per splice in dB, then press to continue.
9) Highlight the other wavelength to use for this standard and press to
select.
10) Repeat steps 5 through 8 for the second wavelength. Press to return
to the fiber standard selection screen, then press to select the custom standard.
