Unless I'm misreading the requirement, this sounds like a job for a Calient or a Glimmerglass optical switch, capable of non-intrusive bridging and/or insertion. For large jobs, in any case.

Because of some reasons, I have to install some giga fiber tap for packet monitor into critical lan point, and the taps must be there permanently.
Some folks speculate the NSA likes using ADC monitor and splitter modules http://www.adc.com/Library/Literature/104215AE.pdf
I prefer using Netoptics network taps http://www.netoptics.com/
I've used both of these, I like them both, so 2 votes for these 2.... :)

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.
