01 Data center cabling  enter into a high density era

With the transformation of the whole society to the digital economy, data centers play an increasingly important role in everyone's daily life. Under the promotion of the national "East number West count" project, the scale of data centers will be larger and larger, and the number of data centers will be more and more, and the traffic of data centers will increase exponentially. In the view of Wu Yiqun, director of iCONEC® integrated cabling Market and Solutions Department, the current development of data center integrated cabling field is relatively stable and will continue to grow in the coming years.

The data center is the base of the digital economy at the national level, and the demand of the client side is large bandwidth and low latency. At the end of data center construction and operation and maintenance personnel, data center cabling is developing in the direction of large bandwidth, low delay and high density. The power of a single cabinet is gradually promoted from 3KW to about 12KW (some Internet enterprises' single cabinet is gradually increased to about 23KW), and the cabling density is from 1U96 core to 1U144 core. Even 1U432 core and other higher density direction.

Wu Yichun said that at this stage, the Internet DC has begun to gradually deploy 400G applications, then 800G and the future 1.6T level of data centers are also attracting more and more attention in the industry, "in the data center high computing power development, as well as the exponential growth trend of data volume, in the same space, to accommodate more ports." Optimizing the cost per U of space used in the data center is also one of the drivers of the cabling density in the data center." At the same time, in the case of high density, how to ensure the stability and security of data centers has naturally become one of the focus topics of common concern in the IDC industry.

Wu Yiqun pointed out that under the background of "East number west calculation", the migration of data centers to 400G will become a major trend in recent years, how to make the current data center from 40G, 100G state smooth migration to 400G or even 800G, which is the topic that the wiring industry needs to think about. In the face of the 400G transmission standard using SR8 or SR4.2 or even SR4, and taking into account the extension needs to 800G, combined with the rise of single cabinet power density, we from the product side, how to think about the design planning stage, iCONEC for these application scenarios, has launched a self-developed solution."

02 Structured help data center "longevity"

Not only this, with the gradual advancement of the "East number and west calculation", the use cycle of the data center has also put forward new requirements, in Wu Yiqun's view, the design life of the enterprise data center in the past is mostly about 10-15 years. However, in the context of "East number west calculation", more and more large and super-large data centers will emerge, how to help the service life of the data center become longer, optimize the cost of ownership during the life cycle of the data center, and reduce the carbon emissions of the data center industry will be another research topic in the wiring industry.

Wu Yiqun said that with the improvement of the service life requirements for data centers, higher requirements have been put forward at the wiring level. The bandwidth of the data center increases with the growth of the service volume, and the modular approach can effectively achieve flexible deployment. "The bandwidth is smoothly upgraded with the service volume, without repeated rewiring, and the advantages of structured cabling are obvious."

Under the general trend of data center modularization, higher requirements are also put forward for integrated wiring manufacturers, "wiring brands need to involve more industries such as HVAC, cabinets, micro-modules and so on." Understanding its technical characteristics and considering the adaptation and linkage between other devices at a deeper level can help the data center achieve modularity in the process of light and heat." Wu Yiqun stressed that this is also in the data center prefabrication, modularization of the general trend, the data center structured integrated wiring product line put forward higher requirements.

03 High-standard optical fibers support the construction of high-standard data centers

With the advancement of digital transformation, the development of enterprises is increasingly dependent on data centers, to security, to stability, to low latency, to green energy saving and so on... The requirements for data center cabling are also getting higher and higher. According to Wu Yiqun, Changxinsheng has rich experience in the field of high-standard data center cabling, especially in the financial industry data center. The financial industry regards data as "money", especially for securities, exchanges, futures and other application scenarios with extremely low network delay requirements, reducing the optical path of light in optical fiber is also a major technological breakthrough, "the users of these application scenarios have great expectations for hollow fiber, Changfei Group has invested a lot of research and development resources in the field of hollow fiber in recent years. There will be a qualitative breakthrough in this field by the end of 2022, and we are pleased that Changfei Group can bring such innovative solutions to the cabling industry." Wu Yiqun pointed out.

At present, only iCONEC® has entered the four major state-owned bank projects and supplies, and iCONEC® provides different solutions according to the different needs of different financial businesses. In the construction project of Nanhu Data Center of China Construction Bank, super six types of shielding are used as horizontal cables, iCONEC® OM4 multi-mode pre-termination optical cable is selected, flame retardant LSZH-3 level is selected, and iCONEC® G4 optical fiber distribution frame is used to achieve 1U 96-core distribution frame density, and the access layer is 10G. The convergence and core adopt 40G speed, the cost performance and foresight of OM4 system bring users the optimal investment plan in the life cycle, fully taking into account the future development trend of the network and the possibility of smooth upgrade.

During the project construction of Jimei Data Center of Xiamen Bank, the iCONEC® team designed a solution with a maximum loss of less than 1dB for the whole link according to the ultra-low loss requirements of the bank. Combined with the trend of high density, the solution of 1U96 core and 1U144 core optical fiber wiring was adopted. It has realized the smooth upgrade of the data center from 10G to 400G, and helped users realize the strategy of gradual growth and gradual investment while creating a high-quality, efficient and high-performance network system.

"The integrated wiring system is the road of data transmission, the" capillary "of the overall network construction of the country, and one of the key factors for whether the" East number and West calculation "project can achieve real value. iCONEC® Cabling will continue to optimize its products and solutions on the basis of its own industry advantages, helping to create a high standard data center, responsible for providing high-quality, stable and reliable "highways" within and between data centers. Wu Yiqun stressed.
