46、 connectors. The cleaning procedure is the same for male and female inserts in either plug or receptacle. 9 Tooling No tools required for insertion/extraction of the optical contact. The optical contact is inserted/extracted by hand from the rear of the connector. The standard tool as per MIL-I-8196
