A demo of the Glimmerglass device can be viewed

This is probably bit more than would be needed for the apparent application of monitoring a particular routing point for a LAN. A
simple passive fiber tap may be sufficient.

An optical switch may be more suitable when you have large numbers of
sources and need to dynamically monitor a subset of different fibers
on a regular basis. Installing a switch is less useful if you need to check a particular fiber on a permanent basis.

Of course, if you already have an "optical DACS" in your network, then
it makes sense to use it instead of installing something else.
