It is a good article. It is missing a few points:
If you are going to do the full efford of cleaning and then microscope
each connector, you would also want to finish off by doing a OTDR scan
of the link. This is your documentation for a clean link.
Always use optics that can monitor the signal level. The reality is that
best practice, as described in the article, will not always be followed.
In most case you will be good anyway as long your optics report back a
signal strength with a good margin. Have your automated monitoring
system watch over those signal levels.
Slightly dirty connectors will often give a sufficient link quality
anyway if you have plenty of power budget to spare. We use many 1G
single mode BIDI optics which cost about 10 USD each for 20 km modules
and most of the links are only 1-5 km. The customer end of those links
are probably all half dirty, but nobody cares as long we get a strong
signal back with power budget to spare.

This is an excellent article regarding fiber cleaning and its
importance. Please do share with other people in our business. I'm
sure lack of proper fiber cleaning causes a lot of unneccessary
outages and operational problems worldwide, partly because people
aren't aware of its importance.
