Problems solved by technology

Most of the remote service equipment AAU needs to be installed in the wild environment. Active WDM equipment can only be used in an environment with constant temperature and stable voltage. also become weaker and unable to transmit over long distances
Therefore, there are certain risks and problems in the use of these two solutions for base station fronthaul

Abstract

The invention discloses a semi-active base station forward transmission system with line protection and based on micro wavelength division. The system comprises a local side service equipment DU pool,local side active equipment with a function of network management monitoring, far-end passive equipment and far-end service equipment AAU, all of which are connected in sequence, the local side active equipment with the function of network management monitoring comprises a first OMPU card, an NMU network management card, a 1U case and three first color light modules with different wavelengths. The far-end passive equipment comprises a second OMPU card and three second color light modules with different wavelengths. The passive characteristic of original wavelength division equipment is maintained, a novel miniature CCWDM module and an optical line protection device are highly integrated in the same board card, and the transmission distance between the local side and the remote side of thebase station is increased with small passive insertion loss and equipment space, so that rapid starting is achieved.

Description

technical field [0001] The invention relates to a micro-wave division-based semi-active base station forward transmission system with line protection, which belongs to the technical field of optical communication. Background technique [0002] With the rapid development of 5G communication technology, new construction or expansion of base stations is being deployed on a large scale. The deep coverage of the base station requires that its deployment location be closer to the user, and the fronthaul of the base station between the DU (Distribute Unit, distribution unit) pool of the central office service equipment and the remote service equipment AAU (Active Antenna Unit, active antenna unit) usually uses optical fiber direct transmission. The traditional fronthaul solution of the drive has a series of problems such as tight pipeline resources, high cable cost, long construction period, difficult expansion, difficult online operation and maintenance monitoring, and easy discon...
