Abstract

The present invention relates to an optical module based on SFP+ medium and long distance transmission. There is a driving circuit and a limiting amplifier circuit. The light receiving component includes: a photodiode and a transimpedance amplifier; a self-checking device is also arranged in the housing, and the self-checking device includes a self-checking data generating device and a data receiving device. Set up a self-test device in the optical module, generate self-test data through the self-test device, perform a data transmission between the light emitting component and the light receiving component to obtain the transmitted self-test data, and then pass the self-test data and the transmitted self-test data through the MCU The controller compares and analyzes the data loss rate, so that the user can effectively confirm the status 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.
