Use cleaning stick and pipe with ethylic alcohol (or equivalent) to clean the front face of the optical contact

34、 and the inside of the sleeve without removing the contacts from their cavities. 4. Use dry clean air can for drying. 5. Inspect optical face 6. Install the sleeve holder (From the female insert). 7. Mate the pair of connectors. See TR 4647 for details. 6.2 Tooling For insertion and extraction of th
