Description
Technical Field
The invention relates to the technical field of optical fiber transceivers, in particular to a control and diagnosis monitoring system applied to an optical fiber transceiver.
Background
The most basic circuits of the optical fiber transceiver include a laser driving circuit and a receiver circuit: the laser driving circuit receives the high-speed digital signal and electrically drives the laser diode to generate equivalent optical pulses, so that the electric signal is converted into an optical signal; the receiver circuit obtains smaller signals from the photodetector and amplifies, shapes and limits the output, thereby converting the optical signals into electrical signals. In addition to these two parts of circuitry, the fiber optic transceiver needs to process, implement additional functions including, but not limited to, the following:
(1) Configuration function: configuring parameters of a laser driving circuit and a receiver circuit to enable the laser driving circuit and the receiver circuit to work in an optimal working state;
(2) Control function: the laser driving circuit, the receiver circuit, the ADC circuit and the DAC are turned on or turned off, so that the laser driving circuit, the receiver circuit, the ADC circuit and the DAC can work normally or enter a low-power consumption mode;
(3) And (3) information feedback: through information feedback, a user can distinguish the working states of the laser driving circuit and the receiver circuit and other potential risks through a serial interface;
(4) Temperature compensation function: through the temperature compensation function, some parameters (such as laser skew efficiency, equalization circuit and the like) of the laser driving circuit or the receiver circuit can be set at proper parameters along with the temperature change, so that the transceiver is ensured to work in a stable state;
(5) Digital diagnostic monitoring function (Digital Diagnostic Monitoring, abbreviated DDM): by the technology, a user can monitor real-time parameters of the optical fiber transceiver, including working temperature, working voltage, working current, emitted light power, received light power and the like, and can help management and prediction of service life of the optical fiber transceiver, service life of a positioning system and compatibility of a detection module;
(6) The storage function: volatile memory is typically included for data exchange with the host computer, and nonvolatile memory is used for storing configuration information and look-up table information for the fiber optic transceiver, along with information such as rate, transmission distance, manufacturer name, serial number, date of manufacture, and compatibility information with various standards.
Currently, most of the optical fiber transceivers on the market cannot fully implement the above-listed additional functions, but the optical fiber transceivers capable of fully implementing the additional functions are also relatively high in cost. Because the conventional optical fiber transceiver is basically implemented by a general-purpose microcontroller integrated circuit until now, referring to fig. 1, the conventional optical fiber transceiver adopts a structural mode of "mcu+laser driving chip+receiver chip", the MCU 1 performs register configuration and status reading on the laser driving chip 2 and the receiver chip 3 through a serial interface, and the MCU 1 is responsible for saving configuration information of the laser driving chip 2 and the receiver chip 3, digital diagnosis and monitoring processing of five analog quantities (including temperature, power supply voltage, laser bias current, emitted light power and received light power), and temperature compensation function. Therefore, the existing optical fiber transceiver has the following disadvantages: the price is high; the MCU 1 cannot simultaneously execute the tasks in the same time, the communication process is easily affected by an upper computer, and when the upper computer frequently accesses the MCU 1, the data exchange between the MCU 1 and the laser driving chip 2 and the data exchange between the MCU 1 and the receiver chip 3 are easily interrupted.
