Abstract: Methods, algorithms, architectures, circuits, and/or systems for dynamically allocating memory for storing parametric data in optical transceivers are disclosed. The optical transceiver can include an optical receiver configured to receive optical data; an optical transmitter configured to transmit optical data; a microprocessor configured to access data for each of a plurality of parameters that are related to operation of at least one of the optical receiver and the optical transmitter; one or more memories configured to store the data at a plurality of locations that are dynamically allocated by the microprocessor; and an interface configured to receive a request for data for one or more of the parameters from a host and provide the data in response to the request. In the present disclosure, the host is unaware of the locations at which the parametric data are stored.

Abstract: A laser output control method and a laser output control device, including a luminous source in the optical interface of an optical transceiver, a proximity detector configured to detect and capture reflection intensity of a luminous beam from the luminous source, an optical processing circuit electrically connected to the proximity detector and configured to receive and process the reflection intensity, and a microcontroller configured to capture parametric information of the reflection intensity, are disclosed. The microcontroller is also electrically connected to a laser driver, to receive parametric information of the optical processing circuit and to regulate the laser and/or laser driver activity based on the parametric information. The laser output control device may effectively restrict the laser output activity and the total laser output energy, which may prevent exposing human eyes to relatively strong laser energy and enhance the security of laser usage and protection for the human body.
