ABSTRACT:
An optic signal transmit system and biasing method and apparatus and system is disclosed to reduce power consumption during non-transmit periods. An optic signal generator receives a bias signal and an outgoing signal. A burst/transmit enable signal enables the transmit system into transmit mode, such as during a transmit window in a time multiplexed environment such as PON networks. A bias circuit biases the driver and/or optic signal generator. To realize power savings, the bias circuit includes one or more stages which are selectively enabled to adequately bias the driver and optic signal generator during transmit windows but disabled during periods when the system is not transmitting. The bias circuit may comprise a current mirror with a reference device, a fixed device, and switched device, which is selectively included in the circuit by a bias switch. The bias switch is responsive to a burst/transmit enable signal or a signal related thereto.
