  • How to Choose the Right 200G Optical Transceiver Supplier in China for Your Network Upgrade?

    Some network operators choose 200G instead of 400G to address rapid datacenter traffic growth. For example, according to LightCounting reports that Facebook will deploy 200GbE before 400GbE, while Google already has begun 2x200GbE optical transceiver. 200G optical transceiver is expected to find acceptance in parts of the cloud and enterprise data center networking space at the same time frame as 400G. As we all know, there are just a few suppliers to provide 200G optical transceiver, so it is vital to choose the right supplier for network operators. Since most companies are unaware of how to choose the right supplier so that they missed the chance to cooperate with the right partner. Here are some ways that will help you verify their effectiveness for your needs.

  • Three Hot Selling 200G Optical Transceivers for Data Center

    The dramatically grew in demand for 100G CWDM over the past year. While 100G continues to ramp, the promise of high volume 400G remains omnipresent, albeit a 2019 phenomenon. Customers need existing technologies that ship in production volumes to fill this industry gap. While 100G CWDM is a mature and well-understood technology and will continue to ramp in the coming year, many of the big Cloud Data Center OEMs are turning their sights to 200G, to meet the pressures of enabling faster connections at scale volumes. 200G optical transceivers with their many advantages such as significantly lower latency, power consumption and cost are coming to market now, and are seen by many as a viable, volume-scalable stepping-stone to 400G. The three hot selling 200G optical transceivers for the data center will be introduced in this article. 200G QSFP-DD SR8 NRZ QSFP-DD ports are backwards compatible with QSFP28 which is very important to provide a smooth upgrade path and links with older systems.  The backwards compatibility of the QSFP-DD allows for easy adoption of the new module type and accelerate overall…

  • Trends in 400G Optics for the Data Center

    Data Center Connections are Driving Optics Volume Due to the ongoing large increase in bandwidth demand, data center connections are expected to move from 25G/100G to 100G/400G. Within the Data Center Racks: 10GE is still being deployed, 25GE is starting to be deployed in volume, and 100GE or 50GE will follow. Between Data Center Racks: 40GE is still being deployed, 100GE is starting to be deployed in volume, and 400GE will follow at large cloud service providers. Long Spans, DCI and WAN: 10G DWDM/tunable is still being deployed, 100G/200G coherent starting to be deployed, and 400G coherent will follow—then 600G or 800G.

  • What Is Data Center?

    A data center is a repository that houses computing facilities like servers, routers, switches and firewalls, as well as supporting components like backup equipment, fire suppression facilities and air conditioning. A data center may be complex (dedicated building) or simple (an area or room that houses only a few servers). Additionally, a data center may be private or shared. A data center is also known as a datacenter or data centre. Data center components often make up the core of an organization’s Information System (IS). Thus, these critical data center facilities usually require a significant investment of supporting systems, including air conditioning/climate control systems, fire suppression/smoke detection, secure entry and identification and raised floors for easy cabling and water damage prevention. When data centers are shared, virtual data center access often makes more sense than granting total physical access to various organizations and personnel. Shared data centers are usually owned and maintained by one organization that leases center partitions (virtual or physical) to other client organizations. Often, client/leasing organizations are small companies without the financial and technical resources required for…

  • Data Center Design: Cost, Technology, Conciseness and Reconfigurability

    100G data centers are maturing, no matter from which angle, the technologies are getting more and more perfect. The 100G data centers can already carry most of the things we want, but at most it only loads the memory and spiritual food of human life—we do see some computations, but such computations are no different from the supercomputing of the previous era. If we don’t understand the goal of data center applications, we can’t design a data center that matches technologies and applications. Optical interconnection technology is moving from 100G to 200G and 400G. Perhaps we can say that 100G optical interconnection has just reached its robust performance in 2018. So we can basically assert that the 100G data centers built before 2018 are all dangerous buildings or houses built on sandy land. We must be aware of the risks. The current large data centers basically follow the 100G CWDM4 structure of the last era, and use AOC and DAC the same time. Today, we need to retell a topic. The proposal is to divide the data center into two…

  • Why Most HPC Systems Use InfiniBand Interconnection

    In addition to the well-known Ethernet, there are many other categories of network architecture. For server-side connection scenarios, InfiniBand (IB) technology is valued and used for its inherent characteristics. It has a nearly dominant position, especially in High-Performance Computing (HPC), large data center storage and other scenarios. So what’s the difference between IB and Ethernet? Why most HPC systems use IB interconnection? What InfiniBand Is and Where It Is Used IB is a “cable switching” technology that supports multiple concurrent connections, and it is the I/O standard of the new generation server hardware platform. With the rapid development of CPU performance, the performance of I/O system has become a bottleneck restricting the performance of servers. The PCI bus architecture used in the past does not conform to the new application trend. To overcome the inherent drawbacks of PCI, Intel, Cisco, Compaq, EMC, Fujitsu and other companies jointly launched the IB architecture, the core of which is to separate the I/O system from the server host. At present, only a few companies, such as Mellanox, Intel, Qlogic, can provide IB products….

  • QSFP-DD Might Be the Mainstream Form-factor of 400G Optical Transceivers

    Time to enter 2019, when 400G has become a hot topic in the optical communications industry, the world’s leading optical transceiver manufacturers have launched their own 400G optical modules. When we list the form-factors of these manufacturers’ 400G optical modules (as shown in the figure below), we found that all the manufacturers except the Finisar (acquired by II-VI) have adopted the QSFP-DD form-factor — the market seems to have recognized QSFP-DD as the first choice for form-factors of 400G optical modules, though some manufacturers have also introduced 400G optical modules with OSFP and CFP8 form-factors. 400G Form-factors of Mainstream Optical Transceivers Manufacturers Tips: QSFP-DD is a high-speed pluggable module form-factor defined by the QSFP-DD MSA group. The QSFP-DD MSA group has defined the next generation, high-density, high-speed pluggable module form factor that addresses the industry need for high-density, high-speed networking solutions in a backward compatible form factor. The QSFP-DD Specification has been developed and refined by many companies within the QSFP-DD MSA group and released to the public. Why do mainstream manufacturers choose the QSFP-DD form-factor? Does this mean that the…

  • The Challenges and Opportunities of Silicon Photonics in the Application of Optical Modules

    The Status of Silicon Photonics Technology in the Application of Optical Module With the maturity of waveguide theory and the production of a series of new design devices, the industry has proposed Silicon Photonics technology based on CMOS manufacturing processes. Silicon Photonics utilizes the very mature silicon wafer processing technology of the traditional semiconductor industry. It can process large-scale waveguide devices on the silicon substrate by etching process. By using processes such as epitaxial growth, it is possible to prepare key devices such as modulators and receivers, and finally achieve high integration of modulators, receivers, and passive optical devices. In addition to the laser, the Silicon Photonics technology can realize the integrated manufacturing of various devices in the optical module, covering most components inside the optical module, but does not include the laser chip. Since silicon is an indirect band gap, the conduction band minimum (conducting band bottom) and the full band maximum are in different positions in k space. The electronic transition needs to change the potential energy and kinetic energy at the same time. The laser needs to…
