Description

technical field [0001] The invention relates to the field of radio frequency communication equipment, in particular to a micropower intelligent optical fiber wireless coverage system. Background technique [0002] The existing wireless signal optical fiber coverage system is an optical fiber repeater system, and its system principle block diagram is as follows figure 1 As shown, the specific working process is: [0003] Downlink: At the near end, the downlink RF signal of the coupler is sent to the non-power RF optical module through the duplexer, and the non-power RF optical module converts the RF signal into an optical signal through the built-in laser and transmits it to the far end through the optical fiber. At the remote end, after receiving the optical signal transmitted by the optical fiber, the non-power RF optical module converts the optical signal into an electrical signal with a built-in PIN optical / electrical converter, then amplifies the electrical signal with ...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, because the low-noise amplifier module, power amplifier module and antenna are not integrated in the non-power RF optical module of the existing optical fiber repeater system, that is: the low-noise amplifier module, power amplifier module and antenna are set separately, not and without The power radio frequency optical module is integrated, so when the optical fiber repeater system is applied to the project, it is also necessary to add a low noise amplifier module, a power amplifier module and an antenna

With the continuous development of non-power RF optical modules, the requirements for its intelligence and integration are becoming more and more intense, and the existing one-to-one communication mode cannot meet the needs of use
