Depends on the cable's structure. But it's perfectly legitimate to informally call a refraction at such a small
scale a reflection. That's done even with the ionosphere. In any case, it addresses your question as to how
light can be made to follow a curved path. AT&T did something similar on a much larger scale with their old Long
Lines microwave repeaters, some of which were even passive. That was an investment of billions in something that
would have been totally unnecessary if the Earth was flat -- which it's not.
