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。

HISILICON SEMIConDUCTOR Huawei Confidentia Huawei Easy Macro (AAU3240) Product Description Computer Hardware and Network II/Ye Computer Professional Funds
 
Material. AAU3240 Product Instructions AAU3240 Product Instructions document Version Huawei meto 1000 is Huawei\'s optical transmission equipment, originally called 155/622H, group road 155 Mbt/light.
 
Port or 622Mbt/s optical port. The branch is 2Mbit/port or 10M/100MR45 network port. The device does not support 25Gbit/s and 10Gb/s optical ports. Usually used in access networks, such as base
 
Access Service for Station Transmission
 
The higher level is Huawei meto 3000, originally called opt_x 2500+, which supports 25Gbt/s optical port at high speed on group roads. It is an analog Loucent ADM 16/1 device with quite good technology.
 
Familiar, a lot of running in the current network
 
Lower than it is Huawei Metro 100, which is mainly used in the business halls of banks, taxation and ATM (ATM) access services.
 
This kind of equipment is very simple. It is usually installed directly in the integrated cabinet of the small computer room. The integrated cabinet is generally 600 mm (width)*300 mm (depth)*2000 mm (height), according to the cabinet route.
 
The cabinet with slightly different height has a top DC power distribution 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 the integrated cabinet is directly derived from the header cabinet or switching power supply in the computer room. When Metro 1000 is installed
 
Install it directly in the integrated cabinet, and then connect one main (working place, 48V) one equipment (working place, - 48V) and a protective ground wire from the integrated cabinet top power module to a total of five power lines. however
 
After that, the 2M wire on its branch business board is connected to the DDF terminal board in the integrated cabinet, the 10M100M wire is connected to FE-DDE, and the four groups of tail fibers (one group in the East and one group in the west) are connected.
 
Road optical port, each optical port includes one receiving and one sending two tail fibers) leads to ODF sub-frame, connects to the external cable, thus completes the hardware installation work. Next is the equipment power-on test.

AAU is called active antenna unit. In the traditional way, two RUs are seleced to connect to a passive antenna under multi-band networking. After AAU is adopted, two RRUs are integrated into the antenna.
 
Active antenna unit AAU.
 
After more than ten years of construction, upgrading and transformation of mobile network from 2G to 3G, a considerable number of stations have become increasingly tense, and the increase of new equipment will greatly aggravate transportation.
 
In order to meet the increasing cost of construction and operation, operators need to rapidly expand network capacity to meet the growth of business. At present, the construction of LTE in the barracks has started rapidly and needs to be improved.
 
On the basis of existing mobile sites, a layer of LTE (FDD and TDD) network is added, which puts forward new requirements for the space of the station room and the location of the sky. According to Huawei\'s internal investigation and experience, it is necessary to add a layer of LTE (FDD and TDD) network to the existing mobile sites.
 
about 45% of the stations in most of the second-tier cities are crowded, and it is impossible to add independent antennas. Under the mode of multi-frequency and multi-plain network construction, how to make efficient use of limited site resources is further discussed.
 
Upgrading network capacity and providing users with better broadband service experience have become the main challenges faced by operators.
 
Active antenna solutions represented by Huawei AAU are gradually becoming the trend of the industry. From the GSM macro base station in the 1990s to Huawei\'s distributed base station in 2004
 
In the era of MBB, it is necessary to further improve network performance and solve the problem of sky acquisition. Huawei is leading the industry.
 
Promoting Standardization of Active Antenna
 
AAU is called an active antenna unit. As shown in Figure 1 below, under multi-band networking, the traditional method requires two RRUs to be connected to a passive antenna. After using AAU, two RRUs 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 be added, a new set of RRU, antenna, and related accessories will be needed, while Huawei\'s AU solution can be used.
 
To integrate the new band LTE RRU into AAU and the original two antennas, as shown in Figure 2 below.
 
Huawei\'s AAU effectively integrates the operators\'sky resources, simplifies the sky supporting requirements, integrates radio frequency unit and antenna into a body, reduces feed loss, enhances coverage 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 same as that of single-frequency antenna. It reduces the difficulty of site selection and property coordination. At the same time, the design of cluster cables requires only four feeders to connect AAU with the original AAU. In festival
 
With 70% space saved, 30% to 70% capacity gain can be achieved.
 
AAU itself supports a variety of electrical regulation modes. Manual, proximal and distal can easily adjust the dead line. The remote mode can be realized through AISG interface and remote network management.
 
Credit-free station, rabbit tower, improve maintenance efficiency can be adjusted in real time to avoid business interruption.
 
It saves money and time, realizes rapid construction, reduces the 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 site construction by 30%.
 
Huawei\'s AAU can integrate two RF units and antennas in different frequency bands, which is twice as integrated as similar products in the industry. It helps operators to smoothly evolve to HSPA+, LTE and LTE-Adva.
