As above, and first is standby several for digiboard 21 and second for situation during optical fiber repeater normal work with backup handoff functionality
Letter stencil 22 all only receives data without transmission data；When main 1 non-normal working of digiboard, first substitutes master for digiboard 21
Digiboard 1 performs the tasks such as data processing, the control to RF switch and the monitoring to amplifier, and second supervises for digiboard 22
The first working condition for digiboard 21 is surveyed, when first for 21 non-normal working of digiboard, second switches for digiboard 22, replaces
Generation first for digiboard 21 perform data processing, to the control of switch, to tasks such as the monitorings of amplifier and power supply, with such
It pushes away；When the digiboard of work at present detects main 61 failure of power amplifier, big signal RF switch 8 is controlled to be switched to first standby
Power amplifier 621 when detecting first for 621 also failure of power amplifier, controls big signal RF switch 8 to be switched to the
Two for power amplifier 622, and so on；When the digiboard of work at present monitors main 71 malfunction and failure of low noise amplifier, control
Small-signal RF switch 9 processed by circuit switching to first for low noise amplifier 721, when monitoring first for low noise amplifier 721
When also failing, control small-signal RF switch 9 by circuit switching to second for low noise amplifier 722, it is more for low noises when having
During amplifier 72, and so on；Identical, when the digiboard of work at present monitors 121 failure of main power source, control switching switch
11 by circuit switching to the first stand-by power source 1221, and when monitoring the first stand-by power source also failure, control switching switch 11 is by circuit
The second stand-by power source 1222 is switched to, and so on.In this way, the optical fiber repeater of backup handoff functionality should be carried to digiboard, work(
The switching times of rate amplifier, low noise amplifier and power supply increase with the increase of corresponding component setting quantity, improve straight
Put the ability of station reply failure.
In conclusion the optical fiber repeater provided by the present invention with backup handoff functionality, straight compared to existing optical fiber
It puts station and increases backup to digiboard, power amplifier, low noise amplifier and power supply, and accordingly increase combiner and branch
Device so that in main digiboard 1,121 malfunction and failure of main power amplifier 61, main low noise amplifier 71 or main power source, Neng Goutong
Combiner, splitter and switching are crossed accordingly for digiboard 2, standby power amplifier 62, standby low noise amplifier 72 or standby electricity
Source 122 does not need to immediately repair trouble unit, without power-off, avoids system interruption of work due to failure, and need not cut
Whole system is changed, reduces influence of the switching to communication, greatly improves the efficiency and stability of switching system.Meanwhile pass through
Combiner and splitter use so that standby digiboard 2 is also in information re-ception state always, is always maintained at the clock with the whole network
It is synchronous, therefore be switched to, without synchronize again, to further improve the switching efficiency and stabilization of system during digiboard 2
