Step 5 - Break out each separate OFCC or loose tube furcation cable from the group or bundle and, if not already done, slide the heat shrink tubing with the fiber identification over the connector or splice onto the OFCC or loose tube furcation cable jacket.

NOTE:        The heat shrink tubing should normally be pushed up the OFCC or loose tube furcation cable before the OFCC or loose tube furcation cable is terminated.        If the heat shrink is not put on before the connector or splice, heat shrink is available that can be installed after the connector or splice is installed.

NOTE:        Do not install heat shrink tubing on 900-micron fibers.  In those cases where 900-micron fiber is present going into a splice, the shrink tubing should be installed in a region where there is an OFCC.

Step 6 - CAUTION:  Do not overheat the OFCC or loose tube furcation cable.

Prolonged exposure of the OFCC or loose tube furcation cable jacket to temperatures in excess of 160 degrees Celsius (oC) [320 degrees Fahrenheit (oF)] may damage the OFCC or furcation cable jacket. Discontinue heating of the tubing and allow the OFCC or loose tube furcation cable jacket to cool before reheating if the OFCC or furcation cable jacket shows any signs of bubbling.

Holding the heat gun approximately 100 mm (4 in) away from the OFCC or loose tube furcation cable and tubing, shrink the tubing.
