What could be used to repair a bent fiber optic cable?

Repairing a bent fiber optic cable typically requires ensuring that the cable is not permanently compromised, as severe bends can damage the fiber strands within. When faced with a bent fiber optic cable, none of the provided choices would be considered appropriate repair methods.

Heat shrink tubing may be used in the context of protecting or reinforcing a connection or splice, but it does not address the bending issue itself. The tubing is not designed to restore the integrity of a bent cable; it merely serves as a protective cover.

Connector replacement may be necessary if the connectors themselves have been damaged, but it does not resolve the underlying issue of the bend in the optical fiber. It is also crucial to note that replacing a connector does not fix the cable if the bend has caused damage to the fibers.

Splice adjustment involves rejoining fibers that have already been spliced, but it would not rectify a physical bend in the cable. If the fibers inside the cable are bent too severely, they may need to be replaced entirely, as adjusting splices won’t fix a cable that has been compromised.
