Your theoretical cable has near zero energy and is almost entirely mass.
Black holes (collections of mass) pull on mass much more than energy.
Your cable would be pulled apart - ie spaghettified - long, long before it reached an event horizon, given an event horizon is the point where even a massless particle like light can’t escape.

Light is nearly pure energy with no mass.
