New system applied to 5G fronthaul semi-active solvable pilot tone modulation

Abstract

The invention relates to the technical field of 5G forward transmission semi-active solvable pilot tone modulation systems, and discloses a new system applied to the 5G forward transmission semi-active solvable pilot tone modulation. The system comprises a backboard connector, a network management system, an MCU and an optical line protection module; the network management system is in network connection with the backboard connector, the backboard connector is in network connection with the MCU, and the MCU network is connected with a digital-to-analog converter. An optical fiber line passes through an optical fiber branching device, 3% of light is split and connected into an optical probe to detect the light intensity, the light intensity is input into the analog-digital converter throughthe preamplifier, the optical power of the optical fiber line is calculated through the processor, and the optical power real-time monitoring function is achieved. When the processor detects that a main line breaks down, the state of a standby line is detected immediately, if the standby line is normal, the processor drives the optical switch to be switched to the standby line, and service is transferred to the standby line to be transmitted without causing service interruption.

Description

technical field [0001] The present invention relates to the technical field of 5G pre-transmission semi-active demodulator roof systems, in particular to a new system applied to 5G front-haul semi-active demodulator roof systems. Background technique [0002] As a new generation of mobile communication technology, 5G has the characteristics of large bandwidth, low latency and massive connections. 5G can bring revolutionary business experience to users, and can also develop new business models, providing new impetus for continuous growth of communication operators . Now there are wavelength-adaptive metropolitan access WDM systems with port wavelength-independent characteristics suitable for single-channel rates of 10Gbit / s and 25Gbit / s, and the maximum number of channels is 12 / 20 / 40 waves, which can be applied to mobile fronthaul and Scenarios such as leased line access. The OAM function supports end-to-end monitoring and management of OpenWDM equipment, modules and optica...
