Photoelectric conversion system

Technical Field

The utility model relates to a communication system, network system, application fields such as optical communication, in particular to photoelectric conversion system.

Background

With the rapid development of network technology, more and more product forms appear, and especially in the transmission situation, communication systems exist in various forms. From the aspect of transmission form, the transmission mode comprises wired transmission and wireless transmission; on the basis of wired transmission, the main transmission media such as coaxial cable, ethernet, optical communication and the like are divided. Among such many transmission media, the most intimate contact with our users is optical communication, wireless communication, coaxial cable (limited television, etc.), and ethernet, which is connected to every computer in our home or office.

Because of the limitation of the application scenario, the standard definition mainly considers the application of the local area network system, so that only transmission within 100m is generally considered on the transmission distance, and low-rate transmission within 1000m is mainly considered on special occasions. The disadvantage is short transmission distance and easy interference.

Optical communication is mainly considered to be accessible from a far end in a transmission system and an access system, the transmission distance is usually more than 1km, and large-capacity data transmission is mainly considered. The disadvantages are as follows: special signal processing (photoelectric conversion) is required, and special equipment is required for access. The advantages are that: large capacity transmission, long transmission distance, high reliability, difficult interference and the like.

The existing network communication mainly depends on optical communication access of a switch or near-end ethernet access, and the equipment for solving the photoelectric conversion is usually realized by adopting the switch or a common optical modem (home or enterprise optical access equipment), but the processing mode increases the complexity and the cost of a switch system, and simultaneously increases much uncertainty, poor maintainability and complexity in the aspects of network management and monitoring.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1, a photoelectric conversion system is characterized by comprising an MCU module for initializing a system, wherein the MCU module is connected with a photoelectric conversion module, a power supply module and a wireless module, and the photoelectric conversion module is connected with an expansion module, an electrical port and an optical port.

The wireless module is a zigbee module, a Bluetooth module, a 4G module or a 5G module.

In the device use, the MCU mould for the initialization system, the system expansion, wireless module's management and communication, physical layer photoelectric conversion module's configuration and data monitoring, wireless module is used for remote management, monitoring service, physical layer photoelectric conversion module is used for the two-way physical layer conversion function that electric mouth changes light mouth or light mouth changes the electric mouth, expansion interface is used for the power, the system interconnection, monitoring interconnection, expansion functions such as remote monitoring, the light mouth is used for inserting optic fibre input/output interface, the electric mouth is used for inserting ethernet input/output electric mouth.

At present, there are two ways for FTTB and FTTH in a communication system and for fiber optic service to the service of a building:

the first method is that a universal optical modem (namely an optical port when in access, the inside of the optical modem is distributed as an electric port or a wifi wireless interface and is similar to an access gateway) is directly inserted after a fiber is pulled into a building, namely an optical access switch is distributed to a user or an office, and each user or each office is distributed with a network cable to be accessed into the own internal switching system of the user or the office;

and secondly, the optical fiber is distributed to optical cats (namely, an optical port is accessed, the inside of the optical port is distributed into an electric port or a wifi wireless interface, and the like is accessed to a gateway) of a home or an office through an optical distributor, and the home or an office is further respectively arranged in an Ethernet internal switching system.

In summary, in the current design for fiber to the building or fiber to the home, the network monitoring and detection after the fiber to the home is not considered at first, and at present, only the state detection and monitoring from the equipment to the home is concerned on the technical level, and the network state in the home of the user does not provide the necessary detection means.

In the scene, the system is adopted at the optical fiber access end, and the network interface is directly adopted in the system, so that the access and conversion of various interfaces can be reduced, and the possibility that the access equipment directly impacts the user equipment can be reduced. The system has the functions of loopback detection, monitoring and remote management, and operators or users can carry out loopback diagnosis and detection on self networks. Meanwhile, real-time monitoring and remote management can be carried out according to the network state.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
