Abstract
The utility model discloses an optical fiber repeater and relates to the technical field of the communication. The optical fiber relay device includes an antenna feeder system, a near-end machine, a near-end light distribution box, a far-end light distribution box, and a far-end machine. The antenna feeder system, the near-end machine, feed system, and the near-end light distribution box are sequentially connected; and the near-end light distribution box is connected with the far-end machine through a cable. The optical fiber repeater receives and amplifies the locomotive radio signal, and then transmits the locomotive radio signal in the strong carrier, so as to ensure that the wireless communication is not interrupted.
Description
Technical field
The utility model relates to communication technical field, be specifically related to a kind of Optical fiber relay equipment.
Background technology
When traditional Optical fiber relay equipment is used on smooth road, the signal of radio communication is fine, can keep radio communication not interrupt, but in some cuttings that deep-cut and bend or tunnel, the place of intermountain, hindered the electromagnetic wave propagation of station radio set, wireless signal does not cover, form the strong district of feeble field, and general method adds cement electric pole every a segment distance exactly on the strong district of feeble field curb, generally hang leaky cable, but the difficulty of construction of this method is larger, has brought some inconvenience for people's use.
The utility model content
For the deficiency existed on prior art, the utility model purpose is to be to provide a kind of Optical fiber relay equipment, and repeater can receive the locomotive radio signals, after amplification, send with stronger carrier wave, thereby the assurance radio communication is not interrupted.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of Optical fiber relay equipment, comprise antenna-feedback system, near-end machine, near-end Optical cross connects case, far-end Optical cross connects case and remote termination, antenna-feedback system, near-end machine, near-end Optical cross connects case are connected successively, and near-end Optical cross connects case is connected with remote termination by optical cable.
As preferably, described remote termination is connected with retransmitting antenna.
As preferably, be provided with optical transmitting set and optical receiver in described Optical cross connects case.
Repeater of the present utility model can receive the locomotive radio signals, after amplification, send with stronger carrier wave, thereby the assurance radio communication is not interrupted.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of Optical fiber relay equipment, comprise antenna-feedback system 1, near-end machine 2, near-end Optical cross connects case 3, far-end Optical cross connects case 4 and remote termination 5, antenna-feedback system 1, near-end machine 2, near-end Optical cross connects case 3 are connected successively, near-end Optical cross connects case 3 is connected with far-end Optical cross connects case 4 by optical cable, and far-end Optical cross connects case 4 is connected with remote termination 5.
It should be noted that described remote termination 5 is connected with retransmitting antenna.
In addition, in described Optical cross connects case 3, be provided with optical transmitting set and optical receiver.
This embodiment is sent into near-end machine 2 by the station radio set radiofrequency signal by antenna-feedback system 1, by near-end Optical cross connects case 3, radiofrequency signal is converted to light signal, delivers to remote termination 5 by optical fiber transmission, after amplifying, passes through antenna transmission, for the covering in the strong district of feeble field; The radiofrequency signal of remote termination 5 antenna reception travelling carriages, carry out the electric light conversion after radiofrequency signal is exaggerated, and deliver to near-end machine 2 by optical fiber transmission, and near-end machine 2, by after opto-electronic conversion, light signal being reduced to radiofrequency signal, is sent into station console by coupler.
The repeater of this embodiment can receive the locomotive radio signals, after amplification, send with stronger carrier wave, thereby the assurance radio communication is not interrupted.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
