摘要： A technique enables the transfer of signals in subsea well applications. The technique allows a communication signal and a power signal to be transferred through a single penetration disposed through a tubing hanger of a subsea tree. The communication signal and/or the power signal is converted so as to enable communication along a twisted pair for transfer downhole.
