Abstract

The invention relates to the technical field of optical communication, in particular to a medium-wave light splitting module with operation, maintenance and management. The module comprises a light emitting assembly, a light receiving assembly and a laser driving circuit, the optical module further comprises a microcontroller, a transmitting clock recovery circuit and a receiving clock recovery circuit. The emission clock recovery circuit converts a modulation signal of the mainboard into modulation current and inputs the modulation current into the laser; the microcontroller sends out a top adjusting signal, and the top adjusting signal is loaded on the driving signal after passing through the operational amplifier circuit to obtain a modulated light signal with the top adjusting signal; The light receiving assembly receives the modulated light signal; one part of the output electric signal is subjected to modulation signal amplification through the high-bandwidth transimpedance amplification circuit and then is output to the receiving clock recovery circuit for clock recovery; and the other part is filtered by the low-bandwidth circuit and outputs a top-adjusting signal to the operational amplifier circuit and the microcontroller for demodulation of the top-adjusting signal. The medium-wave light splitting module with the OAM function is simple in circuit structure, low in power consumption, small in packaging, low in cost and high in reliability, and the transmission rate of 24.33-25.78125 Gbps is low.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a medium-wavelength splitting optical module with operation, maintenance and management. Background technique [0002] At present, the connection of wireless access to the 4G network is mainly the interconnection between people. The connection between people and things, things and things, thus forming a broader and open world of the Internet of Things. In order to meet the increasing bandwidth demands and people's lifestyles, higher connection bandwidth demands are proposed. With the development of the optical communication industry, there is more and more demand for SFP (Small Form-factor Pluggables, small hot-swappable) products. The SFP optical module is a small hot-swappable optical module that conforms to the definition of the MSA protocol. The optical communication system provides the function of two-way data transmission. For the optical module solution of ...
