Abstract

The invention relates to an optical module based on SFP + middle and long distance transmission. The optical module comprises a shell, wherein an optical transmitting component, an optical receiving component, a circuit chip and an MCU controller are arranged in the shell; the circuit chip is integrated with a drive circuit and a limiting amplifier circuit; the optical receiving component comprises a photodiode and a transimpedance amplifier; and a self-test device is also arranged in the shell, and the self-test device comprises a self-test data generating device and a data receiving device. According to the optical module disclosed by the invention, the self-test device is arranged in the optical module, the self-test data is generated through the self-test device, the optical transmitting component and the optical receiving component are subjected to primary data transmission to obtain the transmitted self-test data, and then the self-test data and the transmitted self-test data are compared through the MCU controller to analyze the loss rate of the data, and thus users can effectively determine the state of the optical module.

Description

technical field [0001] The invention relates to an optical module transceiver system, in particular to an optical module based on SFP+ medium and long-distance transmission. Background technique [0002] The existing 10G SFP+ long-distance modules all use expensive 1550nm cooling lasers imported from Japan or the United States, and the laser drive circuit scheme is also a relatively high-cost cooling laser dedicated drive circuit. Moreover, when the optical module is in use, the user cannot judge the quality of the optical module. If the data is lost during the transmission process, the user cannot confirm it in time. However, in the existing optical receiving components, transimpedance amplifiers are generally used to analyze the received data. For pre-amplification, the sensitivity of the ordinary TIA-packaged data receiving component is generally only -15dBm, and the higher the sensitivity of the data receiving component, the more complete the received data.
