料。AAU3240产品说明书AAU3240产品说明书文档版本华为meto1000是华为的一款光传输设备,原来叫155/622H,群路为155Mbt/光
口或622Mbt/s光口。支路为2Mbit/电口或10M/100MR45型网口。该设备不支持25Gbit/s光口和10Gb/s光口。一般用在接入网上,如基
站传输的接入服务
比它等级高的是华为meto3000,原来叫optⅸ×2500+,群路高速率支持25Gbt/s光口,是仿的Lucent的ADM16/1设备,技术相当成
熟,现网中运行的很多
比它等级还低的是华为 metro100,主要用在银行、税务等的营业厅和ATM(自动提款机)的接入服务上
这种设备非常简单,一般直接安装在小机房的综宗合柜中,综合柜一般是600mm(宽度)*300mm(深度)*2000mm(高度,根据机房走线
架高度稍有差异)的柜子,里面有架顶直流电源分配开关(空开),有DDF(数字配线架)端子板,有ODF(光纤配线架,含熔纤盘)子架
根据实际情况又是还有FE-DDF(以太网数字配线架)。综合柜的架顶电源是从机房的列头柜或开关电源直接引过来的。安装metro1000时
直接把它安装在综合柜里,然后从综合柜架顶电源模块引接一主(工作地、48V)一备(工作地、-48V)和-条保护地线共计五条电源线。然
后将它的支路业务板上的2M线引接到综合柜里的DDF端子板上,将10M100M网线引接到FE-DDE上,将四条群路尾纤(东向和西向各一个群
路光口,每个光口包括一收和一发两条尾纤)引接到ODF子架,接到外线光缆上,这样就完成了硬件安装工作。接下来就是设备加电调测了。

Port or 622Mbt/s optical port. The branch is 2Mbit/port or10M/100MR45 network port. The device does not support 25Gbit/s and10Gb/s optical ports. Usually used in access networks, such asbase
Access Service for Station Transmission
The higher level is Huawei meto 3000, originally called opt_x2500+, which supports 25Gbt/s optical port at high speed on grouproads. It is an analog Loucent ADM 16/1 device with quite goodtechnology.
Familiar, a lot of running in the current network
Lower than it is Huawei Metro 100, which is mainly used in thebusiness halls of banks, taxation and ATM (ATM) accessservices.
This kind of e is very simple. It is usually installeddirectly in the integrated cabinet of the small computer room. Theintegrated cabinet is generally 600 mm (width)*300 mm (depth)*2000mm (height), according to the cabinet route.
The cabinet with slightly different height has a top DC powerdistribution switch (open), a DDF terminal board and an ODF(optical fiber distribution frame, including a fused fibre plate)rack.
According to the actual situation, there is also FE-DDF(Ethernet digital wiring frame). The overhead power supply of theintegrated cabinet is directly derived from the header cabinet orswitching power supply in the computer room. When Metro 1000 isinstalled
Install it directly in the integrated cabinet, and then connectone main (working place, 48V) one e (working place, - 48V)and a protective ground wire from the integrated cabinet top powermodule to a total of five power lines. however
After that, the 2M wire on its branch business board isconnected to the DDF terminal board in the integrated cabinet, the10M100M wire is connected to FE-DDE, and the four groups of tailfibers (one group in the East and one group in the west) areconnected.

AAU is called active antenna unit. In the traditional way, twoRUs are selected to connect to a passive antenna under multi-bandnetworking. After AAU is adopted, two RRUs are integrated into theantenna.
Active antenna unit AAU.
After more than ten years of construction, upgrading andtransformation of mobile network from 2G to 3G, a considerablenumber of stations have become increasingly tense, and the increaseof new e will greatly aggravate transportation.
In order to meet the increasing cost of construction andoperation, operators need to rapidly expand network capacity tomeet the growth of business. At present, the construction of LTE inthe barracks has started rapidly and needs to be improved.
On the basis of existing mobile sites, a layer of LTE (FDD andTDD) network is added, which puts forward new re for thespace of the station room and the location of the sky. According toHuawei's internal investigation and experience, it is necessary toadd a layer of LTE (FDD and TDD) network to the existing mobilesites.
About 45% of the stations in most of the second-tier cities arecrowded, and it is impossible to add independent antennas. Underthe mode of multi-frequency and multi-plain network construction,how to make efficient use of limited site resources is furtherdiscussed.
Upgrading network capacity and providing users with betterbroadband service experience have become the main challenges facedby operators.
Active antenna solutions represented by Huawei AAU are graduallybecoming the trend of the industry. From the GSM macro base stationin the 1990s to Huawei's distributed base station in 2004
In the era of MBB, it is necessary to further improve networkperformance and solve the problem of sky ac Huawei isleading the industry.
Promoting Standardization of Active Antenna
AAU is called an active antenna unit. As shown in Figure 1below, under multi-band networking, the traditional method re RRUs to be connected to a passive antenna. After using AAU, twoRRUs are set.
The active antenna unit AAU is formed in the antenna.
Figure 1 AAU with RRU and Antenna Integration
For an existing RU and antenna site, if LTE services are to beadded, a new set of RRU, antenna, and related accessories will beneeded, while Huawei's AU solution can be used.
To integrate the new band LTE RRU into AAU and the original twoantennas, as shown in Figure 2 below.
Huawei's AAU effectively integrates the operators'sky resources,simplifies the sky supporting re, integrates radiofrequency unit and antenna into a body, reduces feed loss, enhancescoverage effect, and is more suitable.
Combining the demand of multi-band and multi-system networking,it effectively protects the operator's more important core asset,the sky resources. With AAU solution, the whole sky becomes simple,reliable and stable.
Yes, the benefits are
It is easy to deploy and save space. The size of AAU is the sameas that of single-frequency antenna. It reduces the difficulty ofsite selection and property coordination. At the same time, thedesign of cluster cables requires only four feeders to connect AAUwith the original AAU. In festival
With 70% space saved, 30% to 70% capacity gain can beachieved.
AAU itself supports a variety of electrical regulation modes.Manual, proximal and distal can easily adjust the dead line. Theremote mode can be realized through AISG interface and remotenetwork management.
Credit-free station, rabbit tower, improve maintenanceefficiency can be adjusted in real time to avoid businessinterruption.
It saves money and time, realizes rapid construction, reducesthe difficulty of property coordination through one deployment,greatly reduces the rental cost of poles, civil works and floors,and reduces the cost of installation projects.
It is estimated that AAU can reduce the cost of siteconstruction by 30%.
Huawei's AAU can integrate two RF units and antennas indifferent frequency bands, which is twice as integrated as similarproducts in the industry. It helps operators to smoothly evolve toHSPA+, LTE and LTE-Adva.
