| 摘要 |
According to embodiments of the present invention, an optical receiver detects an optical signal, determines the signal strength, and is placed in a power save mode if the optical signal strength falls below a predetermined level. A microcontroller may instruct a transimpedance amplifier integrated circuit (TIA IC) or other circuitry in the receiver to turn off one or more of its components during power save mode. If the optical signal strength rises above the predetermined level, the microcontroller may instruct the TIA IC to return to normal mode.
