Getting Started with Your Fiber Guardian
54 FG-750
Connecting an External Switch
3. Connect one end of a jumper cable (or of a long feeder fiber) to the
OTDR port (units without switch ports), or to any switch port of your
choice on your Fiber Guardian unit.
4. Connect the other end of the jumper cable (or of the long feeder fiber)
to the input port of the external switch.
Note: Depending on the external switch that you have, the input port may be
labelled differently (master port, common port, etc.) or located at the back
of the unit. Refer to the user documentation that came with your external
switch for more information.
Note: Using a long feeder fiber will incur more attenuation, which will have to be
taken into account when calculating the maximum OTDR reach.
Note: It is possible to cascade external switches. You would simply need to
connect one port of an already connected switch to the input port of the
external switch to add.
