Required Accessories
(2) one-meter patch cables – (ensure proper connector type and fiber type)
Checking for Fiber Continuity
The ZOOM 2 can be used to verify continuity of a fiber link, or can be used to
trace an optical fiber if the fibers are not properly labeled. Use the following
procedure to test either multimode and singlemode cables.
Connect a fiber optic light source to the network port under test as
shown at right. Power on the light source according to
manufacturer instructions.
Press
to power on the ZOOM 2 optical power meter, if
necessary.
Press
until the wavelength on the ZOOM 2 matches the
output wavelength of the light source.
Take the ZOOM 2 optical power meter to the opposite end of the link under test, and connect into the first port. If the ZOOM
2 does not detect any optical power, the display will read “LO”. Continue connecting to subsequent optical ports until the
ZOOM 2 display shows an optical power reading.
If none of the ports display an optical power reading, then it is likely that there is a major connectivity problem with the link,
and further troubleshooting is necessary to determine the nature of the problem.
