Problems solved by technology

The specific implementation of transparent AMCC includes baseband overmodulation scheme and radio frequency modulation scheme. If the modulation depth of AMCC signal to data signal is 10%, it will introduce 1dB optical power penalty, which will affect the transmission distance of the system.

no. 7 example

[0300] Based on the seventh embodiment, a WDM-PON 5G fronthaul network includes a sending end device and a receiving end device, and both the sending end device and the receiving end device are set with a transmission system for AMCC information.

[0301] Specifically, in the transmission system set on the sending end device, its transceiver module receives the first service data flow with idle units, the first service data flow is converted into Ethernet PMA interface data, and the AMCC adaptation processing module converts the original AMCC data Perform adaptation processing to obtain the AMCC information to be transmitted, and the processing module writes the AMCC information to be transmitted into the idle unit in the Ethernet PMA interface data, obtains the second service data stream, and then sends it to the receiving end device through the transceiver module.

[0302] Set in the transmission system of the receiving end device, its transceiver module receives the second s...

Abstract

The invention discloses an AMCC information transmission method and a system, which relate to the technical field of communication. The transmission method is used for wavelength division multiplexingpassive optical network WDM-PON to carry an Ethernet signal, which includes: a sending end device identifies an idle unit from a received first service data stream; and the AMCC information to be transmitted is written into an idle unit to obtain a second service data stream, and the second service data stream is sent to a receiving end device. The service data and the AMCC information of the invention are mutually independent, the transmission of the service data is not affected, the loss caused by the transparent AMCC to the optical power budget is eliminated, the complexity of the opticaldevice design is reduced, and the bandwidth resources are fully utilized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for transmitting information of an auxiliary management and control channel (Auxiliary Management and Control Channel, AMCC). Background technique [0002] 5G fronthaul is an important part of 5G network bearer. The 5G cloud radio access network (Cloud-Radio AccessNetwork, C-RAN) needs to support enhanced mobile broadband (Enhanced Mobile Broad Band, eMBB), large-scale machine communication (Massive Machine-Type Communications (mMTC), ultra-reliable and low-latency communications (Ultra-Reliable and Low-latency Communications, URLLC) three application scenarios, distributed node (Distributed Unit, DU) / centralized node (Central Unit, CU) centralized pool The trend of globalized deployment is more obvious, and the substantial increase of 5G sites will lead to very tight fronthaul fiber resources from antennas to equipment rooms. 5G fronthaul ha...
