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
35、e 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 cable through the crimping ferrule. 2. Strip the cable down to the 125 m fibre. 3. Inject epoxy glue with adapted syringe inside the opt
36、ical 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 opti
37、cal contact. 8. Inspection and control. See TR 4647 for details.
