Method for processing data, optical access equipment and optical access system

Abstract

Embodiments of the present invention provide a method for processing data, an optical access device, and an optical access system, which relate to the field of optical communications and can reduce power consumption of devices at the far end. The optical access system includes: optical access equipment and at least one PHY processing entity connected to the optical access equipment. The optical access device receives the first downlink data, and performs first processing on the first downlink data at the MAC layer in the optical access device to obtain second downlink data in the form of a digital electrical signal, and the digital The second downlink data in the form of an electrical signal is respectively sent to at least one PHY processing entity in the form of a digital optical signal; each PHY processing entity in the at least one PHY processing entity receives the second downlink data in the form of a digital optical signal sent by the optical access device data, and perform second processing on the second downlink data in the form of a digital optical signal at the PHY layer to obtain third downlink data in the form of an analog electrical signal, and send the third downlink data in the form of an analog electrical signal to the CM.

Description

technical field [0001] The embodiments of the present invention relate to the field of optical communication, and in particular, to a method for processing data, an optical access device, and an optical access system. Background technique [0002] With the continuous development of communication technology, the application of optical communication technology is becoming more and more extensive; correspondingly, the network access equipment in the traditional communication system has gradually developed into the optical access equipment in the optical communication system. [0003] Taking the optical access device as an Optical Line Terminal (OLT) as an example, at present, during the transmission of downlink signals, the OLT located at the central office (such as a computer room, etc.) first processes the downlink signal after receiving the downlink signal , and then send the processed downlink signal in the form of an optical signal to a cable modem terminal system (Cable M...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned optical communication system, since the CMTS is located at the far end, and the CMTS needs to process the received optical signal at the MAC layer and the PHY layer, and processing the optical signal at the MAC layer and the PHY layer usually consumes relatively large power, so The power consumption of the equipment on the remote side is usually relatively large
