LOSS MODE

OVERVIEW

TEST PROCEDURES

LOSS MODE

After a fiber cable has been installed and terminated, optical loss measurements can be used to measure the
quality of a fiber link. A comparison between the actual power measurement and the reference value
determines how much optical power is lost through the link.

The Fiber OWL 7+ includes a LOSS MODE that measures the end-to-end loss of fiber links, and then stores the
test results in the meter. These data can then be downloaded to a PC for later retrieval and report printing.

APPLICATIONS

While in LOSS MODE, users can perform the following tests:

Optical power/loss measurement

LOSS MODE is indicated at the top of the display.

FUNCTION KEY OPTIONS

Several functions related to LOSS MODE are available via the
yellow function button menu located at the bottom of the display.

toggle between menu lists

take an optical measurement

enter the length of the fiber manually (if known)

change currently selected wavelength (when source is NOT
set to AUTO)

save test result

set an optical reference

change measurement units between dBm (ABS) and dB (REL)

edit link information

resume testing for a previously stored project

view stored test readings

switch to SIMPLE OTDR mode (see OTDR section)
