Reducing to 0.5V with the stagnation pressure at coaxial cable, the voltage transmitted through power interface 4 is 12V, then the reality of optical receiver terminal 12
Voltage is 11.5V, needs blood pressure lowering to change owing to being provided with the array terminal builtin voltage of photoreceiver and ONU, to input electricity
The area requirement of pressure is the highest, and the running voltage of optical receiver terminal 12 can be 10V, and therefore optical receiver terminal 12 can normally work.
Alternatively, central conductor layer 15 can be sub-thread solid copper wire or strands copper cash.
From above technical scheme, owing to power supply and signal mixer 10 are isolated through described by RF-coupled 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
Frequently signaling interface 5, and it is sent to optical receiver terminal 12 by coaxial cable 14, provide running voltage for optical receiver terminal 12；Light
Reception terminal 12 is energized after work, and by power supply and radiofrequency signal interface 5 and coaxial cable 14, radiofrequency signal is sent to power supply
And the power supply of signal mixer 10 and radiofrequency signal interface 5, owing to direct-current coupling module 3 is isolated through power supply and radiofrequency signal interface
5 radiofrequency signals transmitted, and couple d. c. voltage signal 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 pass through power supply and signal mixer 10 can be direct
Power for optical receiver terminal 12, and transmit radiofrequency signal for Set Top Box 7, and the maximum between optical receiver terminal 12 and power supply away from
From being 20 meters, it is not necessary to separately connect longer power line or change Multi-media box 11, reducing difficulty of construction；Solve owing to connecing away from light
The power supply facilities matched with it it is fitted without, it is impossible to for the difficulty of optical receiver terminal 12 power supply in receiving the scope that terminal 12 is nearer
