14 resistivity of axis cable is 62.5 Ω/m, if the distance of the optical receiver terminal 12 in set-top box 7 to multimedia is 20 meters, coaxial electrical
The all-in resistance of cable is 1.25 Ω, and the rated current of light-receiving is 0.2A, so the stagnation pressure in coaxial cable is reduced to 0.25V, through electricity
The voltage that source interface 4 transmits is that 5V reaches the work of optical receiver terminal 12 then the virtual voltage of optical receiver terminal 12 is 4.75V
Make voltage, optical receiver terminal 12 can work normally.
If optical receiver terminal 12 is the array terminal equipped with photoreceiver and ONU, if the light in set-top box 7 to multimedia connects
The distance for receiving terminal 12 is 20 meters, and the all-in resistance of coaxial cable is 1.25 Ω, and the rated current of optical receiver terminal 12 is 0.4A, institute
It is reduced to 0.5V with the stagnation pressure in coaxial cable, the voltage transmitted through power interface 4 is 12V, then the reality of optical receiver terminal 12
Voltage is 11.5V, since the array terminal builtin voltage equipped with photoreceiver and ONU is to need to be depressured conversion, to input electricity
The area requirement of pressure is not high, and the operating voltage of optical receiver terminal 12 can be 10V, therefore optical receiver terminal 12 can work normally.
Optionally, central conductor layer 15 can be sub-thread solid copper wire or strands copper wire.
By above technical scheme it is found that since power supply and signal mixer 10 pass through described in the isolation warp of RF coupling module 2
The d. c. voltage signal that power interface 4 transmits, and coupled RF signal simultaneously, so d. c. voltage signal is sent to power supply and penetrates
Frequency signaling interface 5, and optical receiver terminal 12 is sent to by coaxial cable 14, provide operating voltage for optical receiver terminal 12；Light
After reception terminal 12 is powered on, radiofrequency signal is sent to power supply by power supply and radiofrequency signal interface 5 and coaxial cable 14
And the power supply and radiofrequency signal interface 5 of signal mixer 10, since dc-couple module 3 is isolated through power supply and radiofrequency signal interface
The radiofrequency signal of 5 transmission, and d. c. voltage signal is coupled simultaneously, so radiofrequency signal is sent to radio frequency output interface 1, and pass through
Coaxial cable 14 is sent to the radio frequency reception interface of set-top box 7.The present embodiment can be direct by power supply and signal mixer 10
Power for optical receiver terminal 12, and radiofrequency signal transmitted for set-top box 7, and between optical receiver terminal 12 and power supply it is maximum away from
From that can be 20 meters, without separately connecing longer power cord or replacing Multi-media box 11, difficulty of construction be reduced；It solves due to being connect away from light
It receives in the closer range of terminal 12 and is fitted without the power supply facilities to match with it, can not be the difficulty that optical receiver terminal 12 is powered
