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 a method and system for transmitting AMCC information, and relates to the technical field of communication. The transmission method is used for the wavelength division multiplexing passive optical network WDM-PON to carry Ethernet signals, which includes: the transmitting end device identifies the idle unit from the first service data stream received; writes the AMCC information to be transmitted into the idle unit After the unit, the second service data stream is obtained, and the second service data stream is sent to the receiving end device. The service data and AMCC information of the present invention are independent of each other, not only does not affect the transmission of service data, but also eliminates the loss introduced by transparent AMCC to the optical power budget, reduces the complexity of optical device design, and fully utilizes bandwidth resources.

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...
