  设计原则 1 design principles

(I) High reliability principle

All trunks and levels are dual-routed, with redundancy, and copper cables are added for backup, which can achieve a highly fault-tolerant data center that maintains normal operation during planned downtime of any infrastructure. Data center servers, network equipment, and storage equipment are all connected together and interdependent. Failure of any one channel or port may cause the entire system to run abnormally or even be interrupted. Therefore, the data center cabling system requires extremely high reliability. In addition to the equipment redundancy and physical backup, the wiring system itself is best to use products of high quality and reliability.

(B) the principle of high density

In order to improve the utilization rate of the entire data center, all wiring products must follow the principles of small footprint and high wiring density. MPO /MTP 光纤预连接技术,大大节省了机柜、管道的空间,也提高了数据中心的布线密度和安装维护的效率。 We recommend the use of a high density patch panel and MPO / MTP fiber pre-connection technology, significant savings in the cabinet, the space of the pipe, the wiring density also increases the efficiency of the data center and the installation and maintenance.

小型数据中心架构 3.1 small data center architecture

Small data centers often omit the backbone subsystems and concentrate horizontal cross-connections in racks or cabinets in one or more main wiring areas. All network equipment is located in the main wiring area, connecting the outside of the computer room to support space and telecommunications access The cross connection of the network can also be concentrated in the main wiring area, which greatly simplifies the topology of the wiring. 3 See Figure 3.

中型数据中心架构 3.2 Medium Data Center Architecture

A medium-sized data center generally consists of an incoming room, a telecommunications room, a distribution area, and multiple horizontal distribution areas, occupying a room or a floor. 4 See Figure 4.


FIG 4 the data center topology Medium

大型数据中心架构 3.3 Large data center architecture

A large data center occupies multiple floors or multiple rooms. An intermediate wiring area needs to be set up on each floor or room. As a network convergence center, there are multiple telecommunications rooms for connecting independent office and support spaces. For very large data centers, it is necessary to add a secondary incoming line, and the cables can be directly connected to the horizontal wiring area to solve the problem of excessive line length. 5 See Figure 5.

系统方案优势 4 system solution advantages

u   High density and space saving

12 MPO/MTP 快接式接头,大小仅相当于一个 RJ45 接头大小,是传统布线无法比拟的。 The high-density 12- core MPO / MTP quick connector is used, and its size is only equivalent to that of an RJ45 connector, which is unmatched by traditional wiring. MPO/MTP 模块组合成的 1U 4U 光纤配线架分别实现了最高 72 芯和 288 芯( LC )的安装密度,节约了大量的空间去部署更多的设备。 In this connection, bound MPO / MTP module 4U and 1U combined into fiber distribution frame 72, respectively, to achieve the highest core 288 and the core (LC) mounting density, saving a lot of space to deploy more devices.

u   Stable performance, reliable

And terminating all products tested in the factory, no melting point at both ends of the product, attenuation, pre-connectorized branch special techniques to ensure reliability. 100% 的出厂检测,出厂前两端采用抗压、抗拉的保护管,有效的保护了内部连接器,并带有安装拉手,保证了光缆从生产到部署整个过程的性能稳定、可靠。 All products are 100% factory testing, factory protection tube ends using compressive, tensile, and effective protection of the interior of the connector, and with a mounting handle, to ensure the deployment of the cable from the production stability of the process, reliable .

u   Easy to deploy and upgrade

All the connectors are plug-and-play, and the number of cables is much smaller than traditional wiring, so the efficiency of construction is greatly improved. It may have required a week of wiring and can be completed in a few hours. MPO / MTP cabling products just how simple and more convenient? MPO/MTP 光纤配线架;第二步,拉好两个 MPO/MTP 光纤配架之间的光缆;第三步,将 MPO/MTP 光缆插入 MPO/MTP 模块端口。 Only three steps are needed: the first step is to place the MPO / MTP optical distribution frame in the cabinet ; the second step is to pull the optical cable between the two MPO / MTP optical distribution frames; the third step is to connect the MPO / MTP optical cable Insert the MPO / MTP module port. MPO/MTP 光纤链路的部署只需要几分钟就能完成,而且不需要任何工具,不需要熔接,不需要很多人员(一个人就能完成),也不需要很复杂的培训。 It can be seen that the deployment of an MPO / MTP fiber link can be completed in just a few minutes, and does not require any tools, fusion splicing, many people (one person can complete it), or complex training.

Because it is easy to get started and the wiring is difficult, the managers of the data center can perform simple system changes and expansions on their own for a short period of time, saving time and costs.

u   Applications supporting future networks

40G/100G 网络的应用,避免了因网络设备升级而需要重新布线的情况。 Perfectly support 40G / 100G network applications, avoiding the need to re-wiring due to network equipment upgrades. 20 年以上的使用寿命,但流量增长的速度却在 5-10 年,因此我们需要经常对系统进行升级。 Integrated wiring can provide a service life of more than 20 years, but the rate of traffic growth is 5-10 years, so we need to upgrade the system frequently. Therefore, in order for the wiring to support long-term applications, a certain margin must be reserved for the wiring system, otherwise the wiring must be re-wired in the future. Rewiring will become more tedious, more complicated, and more expensive.

u   Beautiful wiring and easy management

40% 以上,有利于数据中心的通风。 The space occupied by the cables is shortened, and the cable space under the bridge or the floor can be reduced by more than 40% , which is conducive to the ventilation of the data center. It has got rid of the numerous and disorderly cables brought by the use of ordinary fiber optic products in the past, reducing the management difficulty of customers and beautifying the space.
