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.
Required Accessories
Connect a fiber optic light source to the network port under test as
s h o w n a t r i g h t . P o w e r o n t h e l i g h t s o u r c e a c c o r d i n g t o
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.
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.
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.
