Cleaning Instructions
It is essential that the optical interface (ferrule end
faces) of the 3K.93C fibre optic contacts are clean
and free from any kind of debris to ensure the
correct performance and operation of the contact. It
is recommended that the inspection and cleaning
instructions provided by LEMO are used on the
3K.93C connector to ensure the connector
