Fiber access system and method of wireless signal based on tri-network integration

Abstract

The invention provides a fiber access system of a wireless signal based on tri-network integration, comprising a main module, at least one expansion module and at least one far-end module, wherein the main module is used for separating downlink signals from base station signals and converting the downlink signals into optic signals for shunted output, and converting the received multiple optic signals into uplink electric signals, combining and sending the uplink electric signals to a base station after filtering the out-of-band signals; the expansion module is used for converting the downlink optic signals output by the main module into electric signals for amplification and converting the electric signals into downlink optic signals for shunted output, converting the received multiple uplink optic signals into uplink electric signals for combination and amplification and then converting the uplink electric signals into uplink optic signals for output to the main module; and the far-end module is used for converting the downlink signals output by the expansion unit into downlink electric signal for output after filtering the out-of-band signals, separating uplink electric signals from the received uplink signals for amplification, and converting the uplink electric signals into optic signals for output to the expansion module. The fiber access system of the wireless signal has simple structure and low cost as the expansion module is added. The invention also provides a fiber access method of the wireless signal based on tri-network integration.

Description

technical field [0001] The invention relates to a wireless communication technology, in particular to a wireless signal optical fiber access system and method based on triple network integration. Background technique [0002] In the existing one-to-many repeater system, one near-end module can communicate with multiple remote-end modules via optical fibers. When it is necessary to further expand the signal coverage area, more remote-end modules need to be installed. [0003] However, a plurality of remote modules needs to be provided with a plurality of corresponding photoelectric converters in the near-end module, which leads to a complex structure of the main module and difficult implementation of integrated circuit board design. If multiple near-end modules are used to increase the number of remote modules, the number of base stations will be increased and the cost will be high. Contents of the invention [0004] In view of this, it is necessary to provide a wireless s...
