Method for changing data transmission rate of repeater, and repeater

Abstract

The invention discloses a method for changing a data transmission rate of a repeater, and the repeater. The method comprises the following steps: receiving a radio frequency signal from a transmittingend; performing amplification and frequency conversion on the received radio frequency signal; converting the signal subjected to the amplification and frequency conversion into a digital intermediate frequency signal; setting a corresponding channel according to the current channel bandwidth requirements, and selecting the corresponding digital intermediate frequency signal according to the setchannel; performing down-conversion on the selected digital intermediate frequency signal to obtain a baseband signal; and processing the baseband signal to form signal data, and transmitting the signal data through an optical fiber. By adoption of the method disclosed by the invention, a suitable transmission rate can be selected signal transmission according to the actual application requirements, and the device coverage cost is reduced.

Description

technical field [0001] The invention relates to the technical field of optical fiber transmission, in particular to a method for changing the data transmission rate of a repeater and the repeater. Background technique [0002] At present, in the conventional optical fiber repeater, the optical fiber transmission rate between the far and near ends is fixed, and the specific optical fiber transmission rate is determined by the maximum compatible system requirements during system design. With the development of communication technology and the application of new frequency bands and new standards, organizations such as the three major operators or tower companies require equipment to have larger and larger working bandwidths and more and more working frequency bands to support their multi-band or multi-standard coverage requirements , but in the actual coverage application, according to the on-site coverage environment, it often only uses a certain frequency band of the equipmen...

With the development of communication technology and the application of new frequency bands and new standards, organizations such as the three major operators or tower companies require equipment to have larger and larger working bandwidths and more and more working frequency bands to support their multi-band or multi-standard coverage requirements , but in the actual coverage application, according to the on-site coverage environment, it often only uses a certain frequency band of the equipment or a certain section of bandwidth in the entire working bandwidth for coverage application, resulting in waste of the original maximum optical communication transmission rate design, while the large optical communication rate The design needs to be paired with more expensive optical modules, resulting in a waste of coverage investment costs
