Problems solved by technology

[0002] Optical fiber repeaters can effectively solve the problem that the coverage of radio frequency communication base stations cannot achieve ideal coverage due to factors such as building shelter, ground absorption, and space loss. However, traditional optical fiber repeaters usually include fiber optic near-end machines. It is composed of a duplexer, a near-end optical integrated module and a power module. The optical fiber remote machine is composed of a duplexer, a remote optical integrated module, a radio frequency integrated module and a power module. The middle of the optical fiber near-end machine and the optical fiber remote machine It is often connected by single-mode transmission optical fiber, that is, mostly adopts master-slave backup for the optical fiber of the transmission link, or can only achieve parallel backup of some radio frequency modules, and does not have full redundant hot backup of the entire system and cross hot backup of core modules other functions, low reliability

Abstract

The invention provides an optical fiber repeater system which comprises a first near-end machine, a first near-end power module, a first far-end machine, a second near-end machine, a second near-end power module, a second far-end machine, a radio frequency switch, a retransmission antenna, a near-end power heat backup control module, a cross backup control switching module, a first far-end power module, a second far-end power module and a far-end power heat backup control module for respectively controlling the first far-end power module and the second far-end power module, wherein the cross backup control switching module respectively detects and judges whether the first far-end machine and the second far-end machine fail; when any one of the far-end machine fails, a signal is switched to the other far-end machine; when optical integration units or radio frequency integration units in the two far-end machines fail, the signal is switched to the corresponding units which do not fail; and therefore, cross backup of key units is realized.
