40GQSFP+光模块介绍

一、概念1、40G QSFP+光模块40G QSFP+光模块是传输速率为40Gbps的四通道小型可插拔光模块，可以实现网络设备(如交换机、路由器、媒体转换器等类似设备)与光缆或铜缆之间的互连，其结构比CFP光模块更紧凑，因此更适合端口密度大的应用。

二、分类1、40G QSFP+光模块40G QSFP+光模块比较常见的可分为40GBASE-SR4光模块、40GBASE-LR4光模块、40GBASE-ER4光模块以及40G LR4 PSM光模块。

40G SR4 QSFP+光模块的接口是MPO/MTP，拥有4个独立的全双工通道，常与多模光纤一起使用，与OM3光纤跳线一起使用时的传输距离是100m，与OM4光纤跳线一起使用时的传输距离是150m。

40G LR4 QSFP+光模块的接口是LC双工，具有高密度、高速率、大容量、低成本、低功耗的优势，一般与LC单模光纤跳线一起使用，传输距离最大可达10km。

40G LR4 PSM光模块的接口是MPO/MTP，采用了Parallel Single Mode(并行单模技术,PSM)，利用4路并行设计的MPO/MTP接口，传输距离是10km，具有端口密度高、成本低的特点。

40G ER4 QSFP+光模块与40G LR4 QSFP+光模块一样，一般与LC单模光纤一起使用，不同的是，40G ER4 QSFP+光模块将4个10G数据的输入通道转换为4个CWDM光信号通道，每个通道的速率高达11.2Gbps，并将它们多路复用为单通道，用于40G光传输，主要应用于40GBASE-ER4以太网链路、InfinibandQDR和DDR互连、客户端40G电信连接。

三、特点40G QSFP+光模块：1、采用半导体封装技术，内置4个激光器、探测器，可以支持客户高密度单板的需求。

2、需要增加带宽时网络运营商可以在不中断网络服务的情况下增加新的QSFP+光模块。

3、功耗低于3.5W，而旧式CFP模块功耗为8W。

40G QSFP+ PSM AOC有源光缆产品概要40G QSFP+ PSM AOC有源光缆，光口侧采用了8根单模光纤的PSM(Parallel Single Mode)并行单模技术，利用4路并行设计的MPO/MTP接口，实现了2公里的有效传输。

同时40G QSFP+PSM IR4的模块可以直接和远端的10G SFP+ LR（10GBASE-LR模块相连接。

当数据中心距离传输超过300米的时候，与普通40G QSFP+ LR4相比，40G PSM技术提供低成本的解决方案，让客户灵活方便地拓宽其数据中心的规模。

Save the packaging for possible future use.The optical ports of the QSFP+ transceiver must be terminated with an optical connector or with a dust plug. The QSFP+ transceiver must be operated within the specified temperature and voltage limits.QSFP+ InstallationCautions•The QSFP+ tranceiver module is keyed to only be installed one way. However, if forced the wrong way, damage may occur. •Avoid getting dust or other contaminants into the fiber bore of the QSFP+ transceiver module. •Clean the optic surfacees of the optical fiber before you plug them back in to the optical bores of another QSFP+ tranceiver module. • Each port must match the wavelength specifications on the other end of the cable, and the cablemust not exceed the specified cable length for reliable communications.Installing a QSFP+ Module1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metalsurface on your chassis.2. Remove the QSFP+ transceiver module from its protective packaging. Note: Do not remove theoptical bore dust plugs until directed to do so in a later procedure.3. Check the slot orientation. Note that for some devices (e.g., S4224) some slots are “upside down”compared to other slots.4. Position the QSFP+device at the desired installation slot, with the label facing correctly.5. Carefully slide the QSFP+ device into the slot, aligning it with the internal installation guides.Triangleindicates bottomof SFP cageSFP Module Label side top of SFP moduleBaleClasp SwitchFully Inserted SFPSwitch 6. Ensure that the QSFP+device is firmly seated against the internal mating connector. To verify that theQSFP+ is seated and latched properly. a ) Grasp the QSFP+ by the sides and try to remove it without releasing the latch. b) If the QSFP+ can not be removed, it is installed and seated properly. If the QSFP+ can be removed, reinsert it and press harder with your thumb; repeat if necessary until it is latched securely into the socket.7. Connect the fiber cable to the fiber port connector of the QSFP+ device. Make sure the QSFP+release latch is in the up (closed) position when you insert the cable connector into the QSFP+.8. Remove the dust plug from the connector. Save the dust plug for future use.9. Attach an appropriate cable into the QSFP+ module port.10. Attach the other end of the cable into the other device.11. Observe the status LED(s). See the related manual for details.Fiber Cable Physical CharacteristicsThe fiber cable physical characteristics must meet or exceed IEEE 802.3ae specifications:•Single mode fiber (recommended): 9 μm•Multimode fiber (recommended): 62.5/125 μm•Multimode fiber (optional): 100/140, 85/140, 50/125 μmWarning: Visible and invisible laser radiation when open. DO NOT stare into laser beam or view directly with optical instruments. Failure to observe this warning could result in damage to your eyes or blindness. Connecting Fiber CablesTo install the fiber cable, do the following:1. Locate the appropriate fiber cable.2. Install the cable as shown below.Removing a QSFP+ModuleCaution: Be careful when removing the QSFP+ from a device. Some QSFP+ transceiver module temperatures may exceed 160°F (70°C) and be too hot to touch with bare hands. Note: Do not remove and replace the QSFP+ modules more often than necessary; excessive QSFP+ removing and replacing can shorten the useful life of the QSFP+.1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metalsurface on your chassis.2. For future reattachment of fiber-optic cables, note which connector plug is send (TX) and which isreceive (RX).3. Remove the QSFP+ transceiver module:a. If the QSFP+ transceiver module has an actuator button latch, gently press the actuator buttonon the front of the QSFP+ transceiver module until it clicks and the latch mechanism releases the QSFP+ transceiver module from the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull the QSFP+ transceiver module straight out of the module slot.b. If the QSFP+ transceiver module has a bail clasp latch, pull the latch out and down to eject theQSFP+ transceiver module from the socket connector. If the bail clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bail clasp latch. Grasp the QSFP+ transceiver module between your thumb and index finger, and carefully remove it from the socket.4. Replace the Dust Plug.5. Place the removed QSFP+ transceiver module in an antistatic bag or other protective package.Diagnostic Monitoring Interface (DMI)The following DMI port screen and explanation table contains brief definitions of the DMI support offered on some QSFP+ transceiver modules.

光模块SFP+与SFP、XFP、QSFP、QSFP+的区别SFP收发器有多种不同的发送和接收类型，用户可以为每个链接选择合适的收发器，以提供基于可用的光纤类型（如多模光纤或单模光纤）能达到的"光学性能"。

可用的光学SFP模块一般分为如下类别：850纳米波长/550米距离的 MMF (SX)、1310纳米波长/10公里距离的 SMF (LX)、1550 纳米波长/40公里距离的XD、80公里距离的ZX、120公里距离的EX或EZX，以及DWDM。

SFP收发器也提供铜缆接口，使得主要为光纤通信设计的主机设备也能够通过UTP网络线缆通信。

也存在波分复用（CWDM）以及单光纤"双向"（1310/1490纳米波长上行/下行）的SFP。

商用SFP收发器能够提供速率达到4.25 G bps。

10 Gbps 收发器的几种封装形式为XFP，以及与SFP封装基本一致的新的变种"SFP+"。

GBIC(Gigabit Interface Converter的缩写)，是将千兆位电信号转换为光信号的接口器件。

GBIC设计上可以为热插拔使用。

GBIC是一种符合国际标准的可互换产品。

采用GBIC接口设计的千兆位交换机由于互换灵活，在市场上占有较大的市场份额。

SFP （Small Form-factor Pluggable）可以简单的理解为GBIC的升级版本。

SFP支持SONET、Gigabit Ethernet、光纤通道（Fiber Channel）以及一些其他通信标准。

此标准扩展到了SFP+，能支持10.0 Gbit/s传输速率，包括8 gigabit光纤通道和10GbE。

引入了光纤和铜芯版本的SFP+模块版本，与模块的Xenpak、X2或XFP版本相比，SFP+模块将部分电路留在主板实现，而非模块内实现10G模块经历了从300Pin，XENPAK，X2，XFP的发展，最终实现了用和SFP一样的尺寸传输10G的信号，这就是SFP+。

40G/100G QSFP光模块及AOC误码测试评测相信很多设备商和贸易商在订购和进货的时候能立马通过什么来对这些光模块器件进行一些检查和对功能和性能的一些检测，看产品好不好，功能怎么样，心里没有底，不放心等心里暗示，下面介绍一款既方便携带又小巧的光模块测试仪器，确实很方便，我平时就放在包里。

先分享两张图片，确实小巧，大概一本小笔记本的大小。

这款测试仪器的前面板，左边QSFP1是 40G接口，右边的QSFP2接口支持三种速率的。

测试仪器的后面板就是通常见的USB数据线接口，电源线接口和散热口了PS：为了区分不同速率光模块的工作模式，这款仪器在40G模式时灯是不亮的，100G时灯是长亮的，112G时灯是闪烁的，这个在测试时注意看下就OK了。

因为我们的CHECKER的两个端口都支持40G,因此40G AOC/DAC测试时有两种方式，即单台CHECKER模式和双CHECKER模式，下图为单台CHECKER模式测试链接，很方便。

下图是40G AOC误码测试界面，DDM数据和误码信息一目了然，很简洁。

当然我们的设备也支持两台CHECKER 模式40GAOC/DAC测试链接，需要两个GUI界面显示数据，但是操作同样方便。

PS:40G AOC、DAC一端光模块接一台Checker任意端口，另一端光模块接另一台checker任意端口。

关于设备连接与启动下图是设备与PC链接显示图，无需安装驱动程序，仅需一条数据线和电源线，插入待测模块，打开我们为客户提供的客户端，即可实现测试，整个过程过程不到一分钟，操作非常简便，节省您宝贵的时间。

点击客户端（客户端是设备公司的，需要设备公司发个客户端给您），电脑界面显示框如下图总体界面，即模块刚插上去，GUI界面初始化后，左下角显示OK,左上角Type类型有40GQSFP+,100GQSFP28，112GQSFP28,100G QSFP28 A,112GQSFP28 A可选，相当于一台设备可实现多种封装模块的使用，为您省下费用，而且不用带一些列的测试设备，性价比超高同时减轻您的负担。

交换机互联条件之一，因为QSFP+光模块可以满足高密度、高速率可插拔的
解决方案需求。

接下来易天光通信（etulink）给大家普及有关于QSFP+封装
形式的40G 光模块分类和接口类型。

40G QSFP+ LR4 光模块
40G QSFP+ LR4 光模块采用的是MPO/LC 双工光纤连接器，具有高密度、高速率、大容量、低成本、低功耗的优势，其工作原理是激光驱动器对串行
数据的波长进行调制，复用器将调制过的光信号组合在一起进行传输，快到
达接收端时，这些传输的信号再被解复用器被分解成四个传输速率为10Gbps
的通道，然后PIN 探测器或互阻放大器对数据流进行恢复，再将光信号传送
出去，传输距离为10km。

QSFP+是IEEE组织为40G网络定义的一种光模块封装类型，它极大地满足了市场对更高密度的高速可插拔解决方案的需求。

现在，40G网络已经在大多数数据中心十分普遍，而光模块是数据中心设备互连必不可少的组件之一，那么关于40G QSFP+光模块，你了解多少?一、40G QSFP+光模块基础知识40G QSFP+光模块符合SCSI、40G以太网、20G/40G Infiniband等多种标准，它有四个数据传输通道，每个通道的传输速率约为10Gbps，四个通道同时传输可以实现40Gbps的传输速率。

这种光模块主要有两种接口：LC 和MTP/MPO(如下图)，分别用在单模应用和多模应用。

二、40G QSFP+光模块接口规范为了满足市场高密度、高速插拔解决方案的需求，QSFP+诞生了。

作为最常见的封装形式之一，40GQSFP+光模块在速度和密度上都优于4通道CX4接口。

QSFP+光模块的两个基本接口规范分别是40GBASE-SR4和40GBASE-LR4。

前者用在多模应用中，后者用在单模应用中。

40G BASE-LR4 QSFP+光模块符合802.3ba（40GBASE-LR4）标准，与LC光纤连接器一起使用，传输速率可达到40Gbps。

这种光模块有4个数据传输通道，每个传输通道的传输速率约为10.3125Gbps，4个通道同时传输数据可实现40Gbps传输。

40GBASE-LR4 QSFP+光模块通常用在数据中心和因特网交换点之间，与单模光纤一起使用，传输距离最高可达10km。

40GBASE-SR4QSFP+光模块符合802.3ba D3.2（40GBASE-SR4）标准，与MPO/MTP光纤连接器一起使用可实现40Gbps的光学连接。

这种光模块也是通过四个通道进行传输，传输速率同LR4一致。

在数据中心，40GBASE-SR4 QSFP+光模块可以和多模OM3/OM4光纤一起使用，达到100m（OM3）和150m（OM4）的传输，实现两个以太网交换机间的互连。
