What is PAM4 technology

PAM4 — The High-Speed Signal Interconnection Technology of Next-Generation Data Center

What Is PAM4? PAM4 (4-Level Pulse Amplitude Modulation) is one of PAM modulation technologies that uses 4 different signal levels for signal transmission. Each symbol period can represent 2 bits of logic information (0, 1, 2, 3), that is, four levels per unit time. In the data center and short-distance optical fiber transmission, the modulation scheme of NRZ is still…

Traditional switch vs bare metal switch

Will Bare Metal Switch Be Popular in 100G Data Center?

Nowadays, the requirement for bandwidth and transmission speed in data centers is increasing strikingly. To meet the demand for it, networking industries are moving toward a new direction. Focuses previously changing from 1G, 10G and 40G are now shifting to 100G. Therefore, 100G is the trend of data center. According to a report by Dell’Oro Group, bare metal switch vendors lost share in the 100G data center switching market in 2018 while traditional vendors, such as H3C, Cisco and Huawei, gained. Do you agree with that? Let’s take a look at what the bare metal switch is and whether it will be popular in 100G data center?

Do You Know These about Cloud Computing Data Center?

With the increasing of enterprise informatization application system, the space, electricity distribution system and air conditioning refrigeration of data centers tend to be saturated. Simultaneously, the utilization rate of the servers is generally low. In order to solve the contradiction between the development of data center and the rapid growth of information resources, the concept of cloud computing and the…

How Is Active Optical Cable Used in Modern Data Centers?

With the advent of big data, the data center landscape is changing rapidly. There are an increasing amount of high density, high bandwidth applications on the market. At this point, the passive cable or copper cable system are in the cart. Active optical cables (AOCs), as the main transmission medium in high performance computers (HPCs) and data centers ensures the…

Which Is Perfect for Your Business – Data Center or Server Room?

Every enterprise or small business that needed a server was required to invest in its own infrastructure, hardware and maintenance solutions, with all the equipment accommodated in a dedicated room of the office. However, thanks to the cloud technology and the rapidly increasing availability of fiber connectivity, other options like data center have opened up in recent years. So how…

How to Create More Capacity in Data Center

With the ever-increasing demand for more computing power and data center servers, data center manager have the responsibility to chart a data center capacity plan and determine what strategy will accommodate business needs best. Of course, they could just expand to large facilities (upgrading to the advanced switch and fiber enclosures). However, not all IT budgets are increasing, and many…

10G Data Center Cabling Solutions

The rapid development in data center throughput has led to the increasing usage and demand for higher-performance servers, storage and interconnects. And the old 1G Ethernet cannot handle the heavy-loaded solutions in data center any more. As a result, datacenter designers are looking to the expansion of higher speed Ethernet solutions, specifically 10 G and 40G Ethernet. As for 10GbE,…

Which Cabling Solution is Better for Your Data Center

Although cabling only represents less than 10 percent of the overall data center network investment, it outlives most network elements and treated as the most difficult and potentially costly component. With the datacenter cabling ranging from 1G to 10G, 10G to 40G and even to 100G, more complex cabling is required to ensure a good service or scalability for troubleshooting….
