"What does the setup with Hawaiian Telcom Fiber look like?"

Let's first go over Oceanic first.  Everyone knows how Oceanic works.  There is a coaxial line that enters your home from the telephone pole or underground (depending on your location) and terminates at a coaxial splitter.  The splitter “splits” the incoming line to multiple coaxial lines that go to your modem for internet (and telephone) and cable boxes for your tv.  See diagrams.

Hawaiian Telcom Fiber involves a dedicated fiber line to your home.  There is a ruggedized fiber optic cable from the telephone pole or underground (depending on your location) and terminates on a junction box on the outside of your home.  This junction box splices the ruggedized fiber optic cable to an outdoor rated fiber optic cable which is then routed into our home.  Inside your home, the outdoor rated fiber optic cable terminates in a junction box inside of your home which splices the outdoor rated fiber to a normal fiber optic cable.  This normal fiber optic cable then goes to a converter that converts the fiber into a copper line via ethernet and telephone.  The ethernet cable then goes to a modem that provides internet and a witch to connect cable boxes via ethernet.  This is a lot more complicated but the diagram makes it more simple to understand.
