In order it decreases power consumption, decreases production cost, to increase transmission efficiency, the transmission network which possesses two supply of electricity pins and the optical receiver which uses with one stator spin

摘要

A transmitter circuit is provided for interconnecting a network of digital systems and such as multimedia devices. The transmitter has a light emitting diode (LED) and an input pin coupled to the LED. It is configured to receive a digitally programmed output from a driver that depends ON a control signal sent from a receiver that is coupled to the driver. The control signal is sent from a downstream receiver and which has a comparator that is adapted to compare an incoming signal to a predetermined value. A downstream network interface is adapted to compute if the comparison results yields a POWER up or a POWER down value. A downstream transmitter is adapted to send the POWER up or POWER down value as the control signal from the receiver.
