An opto ESC isolates the high-power side (battery and motor) from the signal side (connection to the receiver) by internally transmitting the receiver throttle signal from the input side to the output side of the ESC through an opto-coupler. That's basically an LED sending a light signal across a small gap to a photo cell which receives it, so no electrical connection between the two sides.
A true opto-isolated ESC will not work if you cut the red wire. It needs 5V from the receiver to power the input side of the optocoupler.
From another thread on opto esc. by abenn
Leave the red wire in, plug in some power(12-50volts) and start wiggling wires and connectors on the main power.
