A system for providing power to remote equipment where a transmit unit having lasers transmits laser light over optical fiber to a receive unit having photovoltaic receivers. The photovoltaic receivers convert the laser light to electrical energy for the remote equipment. The receive unit also sends a feedback signal to the transmit unit which the transmit unit uses to determine whether the lasers should be enabled for full power.
A method and system for a telecommunications isolator link using optical fibers that will work for whichever of HDSL , or or HDSL is being used. A feature of the link is that identical circuits can be used at each end of the link.
