How to clean the expanded beam connector?

This instruction covers the cleaning procedure for the expanded beam (EB) connectors and its optical interface (mating face, optical path lenses, EB insert and alignment features). These connectors are non-contacting; therefore, mating the connector without cleaning first typically will not cause permanent damage to the optic interface.
