Abstract: The present invention relates to an optical module and optical module system using the same. The optical module comprises a transceiving unit, an antenna and an MCU. The transceiving unit receives control commands from one or more control computers via the antenna and transfers them to the MCU. Then the MCU processes the control commands and provides feedback information to the one or more control computers through the transceiving unit. In the optical module of the present invention, as a result of an additional IOT wireless unit, the optical module is capable of communicating with remote control computers, thereby achieving remote testing and control for optical modules, instead of using conventional control methods for optical modules.

Abstract: An optical or optoelectronic receiver, an optoelectronic transceiver including the same, and a method and system for protecting a photodetector in the same are disclosed. The method of protecting a photodetector generally includes providing a control voltage to the photodetector so that a current flows through the photodetector, and determining that a transient event has occurred or a transient state exists in the receiver. During the transient event or transient state, the method maintains the control voltage at a normal operating voltage when the current through the photodetector is at or below a predetermined threshold current, and switches the control voltage to a safe mode voltage when the current through the photodetector is above the predetermined threshold current.
