Description
Technical Field
The invention relates to the technical field of communication, in particular to a photoelectric conversion rate self-matching system and a method.
Background
With the rapid development of communication technology, the network speed is increased faster and faster, and the application range of photoelectric conversion is wider and wider. An optical-to-electrical converter (i.e., an optical-to-electrical transceiver) is a device used for data transmission between an electrical signal medium and an optical fiber data link, and includes an electrical port and an optical port for performing optical-to-electrical signal conversion between a twisted pair and an optical fiber. The photoelectric converter receives the electric signal, converts the electric signal into an optical signal and transmits the optical signal through an optical fiber link; likewise, the optical-to-electrical converter receives and converts the optical signal into an electrical signal, which is then transmitted over the twisted pair. Optical-to-electrical converters are typically used in practical network environments where cable coverage is not possible, where optical fibers must be used to extend transmission distances over distances greater than 100 meters, and are typically located in access stratum applications of broadband metropolitan area networks.
In the prior art, an effective speed matching mechanism is not defined in an optical transmission standard, so that the transmission rate when a data transmitting end and a data receiving end establish a communication connection (Link) cannot be adaptively adjusted. For example, a transmitting end currently transmits signals at a transmission rate of 1000M, a receiving end currently transmits signals at a transmission rate of 100M, and the transmission standards adopted by the two ends are different, so that the transmitting end and the receiving end cannot establish a communication connection on an application layer. Generally, a user needs to manually configure physical layer chips of both sides, so that a Link can be established only when a data sending end and a data receiving end are switched to the same transmission standard at the same time, which results in poor user experience.

The method aims at the problem that in the prior art, an electrical interface and second opposite-end equipment negotiate through a twisted pair, and optical fibers do not negotiate or negotiate the rate of a PCS layer, so that an effective speed matching mechanism does not exist in an optical transmission standard, and the transmission rate when a communication connection (Link) is established between a data transmitting end and a data receiving end cannot be adjusted in a self-adaptive manner; the system provided by the invention comprises a photoelectric conversion module 2, a first contraposition device 1 and a second contraposition device 2; the photoelectric conversion module 2 comprises a switching unit (switch) 21, a first automatic detection unit 22 and a first rate configuration unit 23, wherein the switching unit (switch) 21 is used for switching between preset rate matching modes; further, the preset rate matching mode includes an optical follow-up mode and an electrical follow-up mode.
And switching the rate matching mode: if the switch is connected with the optical interface, it indicates that the current photoelectric conversion module 2 is in the electric follow-up light mode; if the switch is connected with the electrical interface, it indicates that the current photoelectric conversion module 2 is in the optical-electrical mode.
After switching, if the current photoelectric conversion module 2 is in the electrical random light mode, the first automatic detection unit 22 detects the rate of the optical fiber port of the first peer device 1, configures the rate of the optical interface according to the detected rate of the optical fiber port, then configures the rate of the electrical interface according to the configured rate of the optical interface, the electrical interface negotiates with the second peer device 2, the first negotiation information includes the configured rate of the electrical interface, and then the second peer device 2 configures its own rate according to the negotiation information, thereby implementing self-matching of the rates of the electrical interface and the optical interface of the first peer device 1 and the photoelectric conversion module 2, and the interface of the second peer device 2.
If the current photoelectric conversion module 2 is in the optical-to-electrical mode, the electrical interface negotiates with the second peer device 2, the second negotiation information includes the rate of the second peer device 2, then the electrical interface configures the rate of the second peer device 2 according to the rate of the second peer device, the photoelectric conversion module 2 matches the rate of the optical interface with the electrical interface according to the configured rate of the electrical interface, the first peer device 1 detects the rate of the electrical interface, and then configures the rate of the first peer device 1 and the photoelectric conversion module 2 according to the detected result, so that the electrical interface and the optical interface of the first peer device 1 and the photoelectric conversion module 2, and the self-matching of the interface rate of the second peer device 2 are achieved.
By adopting the technical scheme, on the basis of setting the automatic detection unit, the switching of the automatic detection unit in the preset mode (namely the optical-following-electricity mode and the electric-following-light mode) is controlled in the negotiation process, so that the self-matching of the interface speed is realized, the time for establishing the communication connection is greatly reduced, the user experience is improved, and the normal automatic negotiation process cannot be interrupted by adopting the system.

Further, the auto-negotiation function is to make the devices at both ends of the physical link automatically select the same operating parameters through the interactive information. The contents of auto-negotiation mainly include parameters such as duplex mode, operation rate, flow control and the like.
In the invention, the electric interface or the corresponding operation rate of the second opposite-end equipment is turned on, and the other equipment is turned off, only the required operation rate is negotiated, and once the negotiation is passed, the equipment at the two ends of the link is locked at the same operation rate.
For example, in the electrical lighting mode, i.e. automatic detection (auto sensing) of the optical interface, the corresponding operating speeds of the optical interface and the electrical interface are turned on and the others are turned off according to the detection result. For example, if the optical interface is in the hundreds of megabytes, the electrical interface automatically turns off gigabytes and turns on hundreds of megabytes, then several negotiations are initiated, and the opposite end links to the hundreds of megabytes, so that the self-matching of the rate is realized without interrupting the normal negotiation process.
