    1.4 Ordering Information Section 11 contains ordering information for LC connectors and kits. 2. Safety Precautions • Safety glasses should be worn at all times while performing the installation procedures. • Avoid skin contact with the epoxy. • Place combustibles away from the curing oven when it is in operation. After the oven has reached its operating temperature, the oven ports and heat tube assemblies are extremely hot [266°F (130°C)].

    5. Close the handles of the heat-strip tool and wait 6 to 10 seconds for the softening of the buffer to occur. 6. Wrap the cord around your index finger and pull the fiber from the tool with one smooth and straight motion.

  • Page 13: Epoxy Preparation

    5. Epoxy Preparation The supplied epoxy comes in a two-part package. A divider separates the resin from the hardener. The divider must be removed to allow the epoxy to be mixed. The epoxy is then loaded into a syringe. Both the epoxy package and the syringe are furnished with the D-182977 (108 338 591) and the D-182983 (108 340 811) Kits of Consumables.

  • Page 14: Connector Installation

    6. Connector Installation Connectors are provided in packages which must be ordered by product codes (see Section 10 for LC Connector Product Codes). Each connector is fitted with a white dust cap to protect the connector tip from damage and contamination. During the connector installation process a holder (provided in the D-182959 Upgrade Kit) is used to protect the fiber protruding from the connector tip and to aid in the handling of the small connectors.

    6.4 Install Crimp Sleeve 1. Slip the cable crimp sleeve assembly over the back of the connector while capturing the strengthening yarn. 2. Using the 1510LC crimping tool (supplied in the D-182959 kit), place the square edge of the connector against one edge of the crimp jaw with the crimp sleeve assembly lying through the crimp jaws.
