25、structions This fibre optic connector provides an easy access to the optical faces and sleeves for cleaning. Cleaning operation could be proceeded as follows: 1. Unmate the pair of connectors. 2. Remove the sleeve holder (For the female insert). 3. Use cleaning stick and pipe with ethylic alcohol (o

26、r equivalent) to clean the front face of the optical contact 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 (For the female insert). 7. Mate the pair of connectors. See TR XXXX

27、for details. 6.2 Tooling For insertion and extraction of the optical contact use the standard tool as per MIL-I-81969/14-3 standard (P/N for size 16). 6.3 Termination instructions General termination operation: 1. Pass the crimping ferrule on the cable. 2. Strip off the cable up to the 125 m fibre.

28、3. Inject epoxy glue with adapted syringe inside the optical ferrule from the front side. 4. Insert the optical contact onto the fibre and the cable. 5. Slide and crimp the rear ferrule onto the body contact, the cable and its strength members. 6. Cure the epoxy glue with an appropriate cure oven. 7. Cleave the fibre and polish the front face of the optical contact. 8. Inspection and control.
