400G form-factors: QSFP56-DD vs. OSFP vs. CFP8

QSFP-DD, OSFP, and CFP8: Which is the Best for 400G?

There are three criteria for a successful form-factor: small size, low power consumption, and interoperability between all systems vendors. As we all know, the SFP/SFP+ and QSFP+/QSFP28 are successful form-factors for 1G/10G and 40G/100G networks. In fact, for 100G networks, there are 4 different form-factors: CFP, CFP2, CFP4, and QSFP28. 100G The transmission departments in telecommunication networks need a pluggable…

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, 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 the data center and the rapid growth of information resources, the concept of cloud computing and the…


How Active Optical Cable is 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 is in the cart. Active optical cables (AOCs), as the main transmission medium in high-performance computers (HPCs) and data centers, ensures the stability…


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 cloud technology and the rapidly increasing availability of fiber connectivity, other options like data center have opened up in recent years. So how should…
