The broadcast/television optical workstation is advantageous in that: the broadcast/television optical workstation is provided with the plurality of optical receiving ports and the plurality of optical transmitting ports and furthermore can automatically finish port switching; the broadcast/television optical workstation has a remote state monitoring function and has advantages of high reliability and stable performance; and the requirement for continuously growing value-added service is satisfied.
Description
Technical field
The utility model relates to a kind of optical workstation, relates in particular a kind of radio and television optical workstation of HFC two-way broadband Access Network.
Background technology
Optical workstation refers to the TV signal of major network by after Optical Fiber Transmission, light signal is converted to radiofrequency signal, then be assigned in a net and go, it completes downlink optical signal and changes the transfer process transmitting to radio television signal and reverse radio-frequency to backlight in HFC two-way broadband Access Network, serves radio and television.Be accompanied by the development of China's information industry, the value-added service of radio and television is now also more and more diversified, for example: video request program, online Web TV paying, IP phone etc.Existing optical workstation can be realized two-way communication, has guaranteed the transmitted in both directions of signal.Due to the continuous increase of value-added service, also more and more higher to the performance requirement of optical workstation.
Utility model content
The utility model provides a kind of radio and television optical workstation, and it has a plurality of light-receiving ports and a plurality of smooth emission port, and the switching of completing port automatically, there is remote condition monitoring function, reliability is high, and stable performance meets the ever-increasing demand of value-added service.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Radio and television optical workstation, it comprises shell and is positioned at descending optical receiver and the up optical sender of shell, described descending optical receiver comprises a plurality of light-receiving ports, described a plurality of light-receiving ports are all connected on the first radio frequency converting switch, described up optical sender comprises a plurality of smooth emission ports, described light emission port is all connected on the second radio frequency converting switch, on described light-receiving port and light emission port, be connected with status monitoring transponder, on described light-receiving port and light emission port, be connected with respectively debugging and monitoring port.In the utility model, a plurality of light-receiving ports are set respectively on descending optical receiver, to receive the light signal of different routes, when a light-receiving port breaks down, the first radio frequency converting switch will be switched to radio frequency on another light-receiving port automatically.In like manner, when a light-receiving port breaks down, the second radio frequency converting switch is switched to radio frequency another light-receiving port automatically, can tackle the generation of emergency case.Status monitoring transponder is monitored the various working conditions of optical workstation, realizes the remote monitoring of optical workstation and remote control backward channel switch, avoids noise to invade.Debugging and monitoring port are connected on light-receiving port and light emission port, when breaking down, are convenient to it to debug and monitor, and are also convenient to optical transmitter and receiver upgrade and improve.Utilize the first radio frequency converting switch and the second radio frequency converting switch respectively light-receiving port and light emission port to be switched, and utilize status monitoring transponder to carry out remote monitoring to optical workstation, effectively raise the reliability of this machine, make its performance more stable, to have strengthened user's experience, meet the ever-increasing demand of value-added service.
Further technical scheme is:
As preferably, described descending optical receiver also comprises Optical Receivers, equalizer, CATV amplifier module, the distributor connecting successively, and the first described radio frequency converting switch is connected on Optical Receivers.Descending optical receiver, on existing basis, is selected CATV amplifier module, and self the characteristic of property due to CATV amplifier module, can effectively improve the reliability of this machine and anodal performance, improves the carrying load ability of complete machine.
Further, described light-receiving port has two.Utilize two light-receiving ports to form key light receiving port and secondary light-receiving port, when key light receiving port breaks down, call light-receiving port.In fact, in order further to strengthen reliability, can set up a plurality of light-receiving ports.
As preferably, on described status monitoring transponder, be connected with two positioning indicators.Positioning indicator shows the state of this machine, and when status monitoring transponder monitors optical workstation and breaks down, positioning indicator lights, and people, with prompting, is convenient to on-call maintenance.
Further, described positioning indicator is LED light.
Compared with prior art, the beneficial effects of the utility model are: in the utility model, adopt the first radio frequency converting switch and the second radio frequency converting switch branch automatically to carry out radio frequency switching to light-receiving port and light emission port, status monitoring transponder is realized the remote monitoring to optical workstation, the reliability of complete machine is improved, stable performance, meet the ever-increasing demand of value-added service, user's experience sense is strengthened.
