Description
Technical field
The present invention relates to a kind of optical fiber integration antenna and method for transmitting signals, is a kind of electronic equipment, is a kind of antenna equipment and method for transmitting signals of radio communication base station use of wireless communication networks.
Background technology
The antenna assembly of radio communication base station comprises fiber optic stretch remote processor unit and antenna module.Fiber optic stretch remote processor unit is that communication base station is handled by the light signal that optical cable sends, and reaches the requirement of inlet radio-frequency power, launches by antenna module again.The fiber optic stretch remote processor unit of 2G generally includes optical-electrical converter and amplifier, and the fiber optic stretch remote processor unit of 3G also comprises baseband processing module except optical-electrical converter and amplifier, along with the progress of radio communication and the raising of electronic circuit integration density, fiber optic stretch remote processor unit also may comprise more contents.Described antenna module comprises that shell, one or more antenna plate are connected with some and fixing part.Traditional fiber optic stretch remote processor unit separates with antenna module, fiber optic stretch remote processor unit normally is built up near the ground of antenna module, antenna module then is installed in eminence, fiber optic stretch remote processor unit by several meters even tens meters long coaxial cables with electrical signal conduction to antenna module.The shortcoming of coaxial cable is that diameter is thicker, and the damage that declines is bigger, long-distance transmissions cost height.Often the antenna module of many sectors of using needs a plurality of amplifiers to be connected with fiber optic stretch remote processor unit by many coaxial cables, and volume and installation complexity are bigger.At first, the problem of decreasing that declines strengthens the emitted power loss, has wasted many energy, and expensive copper cable also makes cost increase.In addition, the density of antenna is increasing in the city, though fiber optic stretch remote processor unit only occupies the soil of several square meters at zero point, this zero point, soil problem in very nervous city, current soil of several square meters also seemed very outstanding.And along with the propelling of 3G wireless communication networks, the density of antenna further strengthens, and the problems referred to above can be more obvious.
Summary of the invention
For solving the prior art problem, the present invention proposes a kind of optical fiber integration antenna and method for transmitting signals.Described integral antenna closely couples together antenna module and fiber optic stretch remote processor unit, gets rid of coaxial cable, the transmission of interactive signal is between the two declined decreases reduce as far as possible, safety and reliability.
The object of the present invention is achieved like this: a kind of optical fiber integration antenna, comprise and be installed in outdoor antenna module, described antenna module is connected with fiber optic stretch remote processor unit by microspur radio frequency coupling assembling, described fiber optic stretch remote processor unit connects long apart from optical cable, described length is connected with fiber optic stretch near-end processing unit in the machine room apart from optical cable, and described fiber optic stretch near-end processing unit is connected with source device.
A kind of antenna signal transmission method that uses above-mentioned optical fiber integration antenna, its step is as follows:
The step of electric light conversion: the rf signal of source device output is converted to light signal and outputs to optical cable by fiber optic stretch near-end processing unit electric light;
The step of long Distance Transmission: by the long Distance Transmission light signal of optical cable;
Opto-electronic conversion and the step of amplifying: the light signal of fiber optic stretch remote processor unit input optical cable transmission carries out opto-electronic conversion, and the conversion back signal of telecommunication carries out signal strength signal intensity through amplifier and amplifies, and reaches the requirement of antenna inlet radio-frequency power;
The step of short-distance transmission: the signal of telecommunication that reaches antenna inlet radio-frequency power is by microspur radio frequency coupling assembling, short-range being sent on the antenna module;
The step of emission: radiofrequency signal is transmitted in the overlay area by antenna module.
The beneficial effect that the present invention produces is: optical fiber integration antenna of the present invention, antenna module and fiber optic stretch remote processor unit are installed together, the middle microspur radio frequency coupling assembling that uses connects, be equivalent to a kind of active antenna device, use optical cable directly to transfer signals to the eminence position that exterior aerial is erect, saved coaxial cable.Because the diameter of optical fiber is very little, light signal declines within 10 kilometers and decreases very for a short time, makes declining between antenna module and the fiber optic stretch remote processor unit decrease minimum, and the antenna package Unit Installation is also very convenient.The use of using optical fiber integration antenna of the present invention to have omitted the soil fully in the very high city of sky line density is for the setting of wireless base station provides advantageous conditions.Owing to all adopt optical signal transmission between source device and antenna, it is of high quality, and has therefore also improved communication quality to a certain extent, and this is very favourable for 3G communication.Owing to used optical fiber integration antenna, though some increase of antenna volume, but the tying down of ground rack that has not had fiber optic stretch remote processor unit, the entire antenna system can simply be installed in lamp stand, electric pole, the top of building, only using a very thin optical cable and power line has been installation.Need not any civil engineering, need not any complex apparatus and install, the saving on the slave unit installing engineering amount is just considerable.
