200G光模块最全解析
200G光模块最全解析光模块市场正稳步向200G/400G发展，虚拟数据中心、物联网（IoT）和云计算不断普及，对更高带宽的需求推动了光模块市场的繁荣。
而今，200G/400G的光模块也已出现，并有望在未来几年继续保持良好的势头。
以下为您带来200G光模块最全解析。
下一代数据中心的主流：200G/400G数据中心光互连市场的主要转变是从10G到40G以及更高的40G到100G，另一个可预见的趋势是逐步淘汰核心网络和数据中心的低速光模块。
100G光器件的新发展为200G/400G光器件铺平了道路。
下一代数据中心在2018年底部署200G/400G以太网，并在2019或2020年成为主流。
总的来说，光模块市场正在向更高的速度，更低的功耗和更小的外形或尺寸发展。
其中光模块封装多采用SFP-DD/QSFP-DD。
SFP-DD小型自动可插拔双倍密度封装光模块，比SFP28或SFP56带宽（25G/50G）提高一倍，支持更高速率（50G/100G）的同时还保持SFP28或SFP56向后兼容性。
QSFP-DD四通道小型可插拔双倍密度封装光模块，由QSFP-DD MSA组定义，比QSFP28或QSFP56的密度增加一倍，8个通道，每通道速率高达25G或50G，因此支持200G或400G光传输。
SFP-DD、QSFP28与QSFP-DD封装（高度线缆）的对比Google、Facebook等互联网巨头数据中心内部流量每年增长幅度接近100%，那些较早部署100G的互联网巨头已经开始谋求更高速率的解决方案，下一代数据中心的方案选择成为了大家所热心关注的话题。
400G以太网的标准先于200G以太网标准完成，这或许反映了业界的心态——更看好400G，或者认为200G仅仅是400G的一个过渡方案。
但是直接从100G跨越到400G实际上是不太科学的。
首先从数据中心方面，我们需要重建超大规模的数据中心，定义新的规范架构，400G时代交换机对机架电力的要求会相当高，传统的风冷散热也更为困难；而400G数据中心会使用到PAM4技术，采用PAM4技术会使系统变得不够透明且难以管理，传统的NRZ技术+并行技术可以使数据中心易于管理。

200G QSFP DD AOC在InfiniBand网络中的应用
200G QSFP DD AOC在InfiniBand网络中的应用随着数据中心的不断深入与高需求，人们对于此领域的拓展研究也在不断更迭最新技术与开发最优性能产品及解决方案。
前段时间易飞扬（Gigalight）发布了200G QSFP DD PSM8光模块，标志着基于NRZ调制的200G低成本数据中心内部平行光互连方案基本完成，也象征着公司在200G解决方案上的领先地位。
不同于业界主张的400G方案，易飞扬（Gigalight）坚持200G的数据中心解决方案，可为客户提供一站式的服务和解答。
本文主要根据现阶段超算中心的发展进程，来分析当前交换机之间InfiniBand技术的特征以及应用领域，其中以200G QSFP DD AOC为例，说明了超算中心互连技术的端口封装形式朝着更高工作带宽发展的现状。
超算系统里的InfiniBand技术根据2017年全球超级计算机500强榜单公布情况，我国无锡“神威--太湖之光”超级计算机以每秒125,435.9TFlop/s的峰值计算能力再次蝉联世界第一名，广州“天河二号”超算系统以每秒54,902.4TFlop/s的峰值计算能力位居世界第二名。
值得注意的是这些超算中心的交换互连技术均采用来自以色列InfiniBand的交换机和网络适配卡。
当前在超算中心互连技术阵营中有以色列的InfiniBand，高性能Ethernet，IBM的BlueGene，Cray和后起之秀Intel的OmniPath，这五大技术占据市场的重要份额，其中InfiniBand和高性能Ethernet占绝对领导地位。
超算中心的互连技术朝着更高带宽、更低延迟、更低功耗和更密的互联端口在发展，而InfiniBand互连技术在当前成为高性能存储互连方案的首选，正是因为其满足了大带宽和低时延的需求。
InfiniBand是一个统一的互连结构，既可以处理存储I/O、网络I/O，也能够处理进程间通信。
它可以将磁盘阵列、SANs、LANs、服务器和集群服务器进行互联，在相对短的距离内提供高带宽、低延迟的传输，而且在单个或多个互联网络中支持冗余的I/O通道，让数据中心在局部故障时仍能运转。

Gigabit Ethernet
众所周知，当前Gigabit Ethernet(千兆以太网)已经将Ethernet世界带入新的纪元，它是下个世纪延伸以太局域网络技术的最佳解决方案。
因为在经济成本的原则下，Gigabit Ethernet 不但能够满足消耗大量网络带宽的应用软件的需要，而且由于使用原有Ethernet的架构为基础，不必更换正在使用的网络和操作系统，因此用户无须放弃旧的Ethernet标准和使用习惯，这在技术转移的层面上极受青睐。
目前，很多主板生产商都将千兆网络传输界面正式纳入到产品标准中，使普通用户也能享受到高速的网络传输功能。
趁着这股Gigabit Ethernet热潮的兴起，下面笔者就为大家介绍一下市面上主流的各种GigaLAN网络控制芯片的技术特点和功能，并对各种网络芯片的传输速度进行对比测试，供各位感兴趣的朋友作一参考。
一、Gigabit Ethernet的由来早在1996年6月快速以太网Fast Ethernet标准（802 3u）获得认证之后，IEEE组织便着手定义1 Gbps Ethernet标准（802 3z）的工作。
正如Fast Ethernet一样，Gigabit Ethernet技术在局域网络工业界大受瞩目，并旋即于1996年6月成立一个由八十多家公司组成的GEA联盟（GigabitEthernet Alliance）。
GEA的任务在于协助802.3z工作小组制定标准，并指导世人Gigabit Ethernet的应用，以及制定客户产品之间的互通性标准。
Gigabit Ethernet打着高出Fast Ethernet数十倍速度的旗号来拓展现有的网络带宽，但是目前到底谁真正用得上1Gbps的网络传输速度呢？因为用户才将网络升级到Fast Ethernet（用于服务器或网络骨干的连接）不久。
而FDDI界面于标准认可的六年后，就在网络骨干和服务器连接领域占有七成的市场。
对Gigabit Ethernet而言，业界无法说服用户从Fast Ethernet升级纯粹只是为了更佳的性能改善。

Installation2.1 System RecommendationGIGAPORT HD+ is not simply a standard digital audio interface card, but a high-resolution device capable of advanced processing of audio content. Even though GIGAPORT HD+ is built to have low-CPU resource dependability, system specifications play a key part in the GIGAPORT HD+s performance. Systems with more advanced components are generally recommended.Minimum System RequirementsPC- Intel Pentium II 300MHz CPU or comparable AMD CPU (or equivalent) – we recommend at least a Pentium III CPU with 600 MHz- Windows XP or Windows Vista / 7 (32- and 64-bit) operating system- 1 available USB port- at least 64MB RAM- high quality audio software with ASIO support recommendedMac- Power Macintosh G3 or higher- 1 available USB port- at least 64MB RAM- Mac OS X 10.4 or higher2.2 Hardware InstallationGIGAPORT HD+ is simply connected to an available USB port of your computer. A separate power supply is not required, as GIGAPORT HD+ is a USB powered device. Simply install the hardware by plugging it into your computer with the supplied cable.USB port of a computer2.3 Driver InstallationAfter the connection of GIGAPORT HD+, the operating system automatically detects it as a new hardware device. Modern operating systems like Windows XP, Windows Vista / 7 or Mac OS X usually detect the hardware directly and are installing the correct USB audio drivers automatically. You can use GIGAPORT HD+ already now in typical consumer audio applications that do not need special professional ASIO driver support. Under Windows XP this could be for example programsused for DVD playback or more simple DJ applications that don’t require ASIO. Under Mac OS X this could be applications like Garageband. Please note that our special driver is also required if you are using higher sample rates than 44.1kHz.Installation under Windows XPUnplug the device before you start the installer if it is already connected. Then launch setup.exe from the GIGAPORT HD+/Windows folder of the included driver CD or from a download of a recent driver from our website.You will now see a dialog as shown on the left picture below. Click Next . You can define the target directory for the installation now. Confirm it with Next .The installer now informs you that the driver installation will start as shown on the left picture below. Confirm this with Next . During the following process you will see a dialog box once or several times that informs you that the driver software has not passed Windows Logo testing. Please be assured that our drivers have been tested in various different ways and are OK to be used. Confirm any such dialog with Continue Anyway .You will now be prompted to connect the hardware on the next dialog that is shown below on the left. Plug in GIGAPORT HD+. Do not click Next yet. During the driver installation, Windowsmight again prompt you to confirm the Windows Logo testing dialog once or several times with Continue Anway before the driver installation is finalized.You can now finally click Next on the ESI GIGAPORT HD+ Audio Driver Setup dialog. The installation is now finished. To confirm this, please check if the ESI icon is displayed in the taskbar notification area as shown below. Sometimes a reboot is required.If yes, the driver installation has been completed successfully.Installation under Windows Vista / 7Unplug the device before you start the installer if it is already connected. Then launch setup.exe from the GIGAPORT HD+/Windows folder of the included driver CD or from a download of a recent driver from our website.When launching the installation, Windows Vista / 7 might prompt a security message. Make sure to allow the installation. You will then see a dialog as shown on the left picture below. Click Next. You can define the target directory for the installation now. Confirm it with Next.The installer now informs you that the driver installation will start as shown on the left picture below. Confirm this with Next. During the following process you might see a Windows Securitydialog box once or several times that asks you for confirmation to install the driver software. Confirm any such dialog with Install.You will now be prompted to connect the hardware on the next dialog that is shown below on the left. Plug in GIGAPORT HD+. Do not click Next yet. Instead, wait a few seconds for the automatic device driver installation. You can monitor this in the task notification area where Windows Vista / 7 informs that the driver is installed via a bubble message box.You can now finally click Next on the ESI GIGAPORT HD+ Audio Driver Setup dialog. The installation is now finished. To confirm this, please check if the ESI icon is displayed in the taskbar notification area as shown below. Sometimes a reboot is required.If yes, the driver installation has been completed successfully.3. Control PanelThis chapter describes the GIGAPORT HD+ Control Panel under Windows. Under Mac OS X no special Control Panel is required.To open the control panel double click on the ESI icon in the task notificationarea. The following dialog will appear:The Output section controls the playback volume of each playback signal from your audio applications.There are eight individual faders for each playback channel, divided into the 1/2, 3/4, 5/6 and 7/8 sections. The M button under each channel pair allows you to mute playback for that specific channel pair. A colored M button indicates that the mute function is enabled. When disabled, the button is gray.The Master section allows you to control the playback volume of the main master signal. SampleRate mode selectionUnder Config > SampleRate, you can select the playback modeand sample rate. By default, playback with up to 8 channelsand 44.1kHz is selected (at up to 16-bit playback resolution).You can change this to 6 channels at max 24-bit resolutionwith either 44.1 or 48 kHz and you can select 96kHz playbackat 24-bit with maximum 2 simultaneous channels.Please note that you must change these settings beforelaunching any audio application accessing GIGAPORT HD+.You cannot change these settings while any software accesses the hardware, so you need to set up your requirements before you launch your software.Latency settingWith the Latency menu entry under Config, you can change the latencyof the driver of GIGAPORT HD+. Depending on the typical application(e.g. for playback of software synthesizers) a smaller latency is anadvantage. At the same time, the best latency setting indirectly dependson the performance of your system. For most default applications, atypical latency buffer size between 128 and 256 is standard. On a slowsystem, 512 is an option.Please note that the latency has to be setup before launching any audio application.4.
