10Gig™ SFP+ Direct Attach Copper Cable AssemblyInstallation Guidelines PN533BIntroductionAs virtualization, consolidation, and convergence initiatives continue to expand in Data Centers, so do the demands placed on the physical infrastructure. To meet the needs for higher bandwidth along with lower power interconnects, Panduit® offers 10Gig™ SFP+ Direct Attach Copper Cable Assemblies.This high speed data transport capability is ideal as server virtualization becomes more prevalent. 10Gig interconnects are needed to facilitate effective server utilization to run multiple virtual machines as well as server consolidation. By incorporating 10Gig™ SFP+ Copper Cable Assemblies into the physical infrastructure, organizations can achieve 10Gig performance without additional signal processing or conversion. This provides an ideal low power, low latency 10 Gbps server interconnect option for top of rack switching deployments.Passive 10Gig™ SFP+ Copper Cable Assemblies generally have a reach limitation of 7m (23 ft.), and many network deployments will consist of a mixed copper/fiber solution with Panduit 10Gig™ OM3 fiber. Panduit 10Gig™ SFP+ Direct Attach Copper Cable AssembliesPanduit 10Gig™ SFP+ Copper Cable Assemblies are factory terminated and constructed of high-speed twin-axial shielded cable with SFP+ modular connectors on each end. The cables are compliant to the SFF-8431 specification.The Small Form Factor committee approved and published SFF-8431 in July of 2009, with Panduit® as a member and a signee. The document covers host ports, optical transceivers, and copper cables. Appendix E specifies direct attach copper cable assemblies.These passive cable assemblies offer a low power, low latency, low cost option for a 10Gig interconnect. They may be plugged into SFF-8431 SFP+ compliant ports and are interchangeable with fiber optic transceivers. (Note: some system vendors have designed copper-only or fiber-only SFP+ ports, so be sure to confirm host port capabilities with the active equipment vendor)The Panduit® 10Gig™ SFP+ Direct Attach Cable Assemblies are constructed with high frequency 10 GHz 100 ohm parallel shielded pairs, with two wire pairs in the cable. Panduit® uses 30 AWG for cables less than 4m in length and uses 24 AWG for 4m and longer cables.The connector consists of a paddle card with patent pending circuitry to ensure superior high frequency signal integrity, is housed in a die cast backshell, and incorporates a latching mechanism that allows insertion and de-insertion into the mechanical cage of a host port on the active equipment. The same host port cage can accept optical transceivers or direct attach cable assemblies. The back of the paddle card has pads which form the contacts to the 20 pin host connector inside the cage. The connector has an EMI shroud that provides 360 degrees of contact with the host cage to ensure excellent EMI immunity.Cross-section 2-pair twin-axial cable Panduit® SFP+ connectorStandard Cable Part NumbersPart Number Length* Cable Gauge Nominal Cable O.D.

However, much of the connector is inserted into the host port. Therefore one may wish to add approximately 47mm or 1.87 in. to each end or approximately 0.1m total to port-to-port length and cord routing calculations.Connector EEPROMPanduit® 10Gig™ SFP+ Direct Attach Copper Cable Assemblies are intelligent cables. The connector has an integrated EEPROM with information populated in registers that is provided to the active equipment when queried through an I2C bus Most active equipment port allow for interchangeable types of me to be plugged into its ports. The registers in the EEPROM provide a method for the connector to identify itself as an SFP+ passive copper module to allow the active equipment to operate in the proper mode. Other information contained in the memory registers includes vendor name (Panduit), part number, serial number, and cable length in meters.SFP+ Cable Assembly Connector Pin OutSFP+ Pin Assignment DefinitionsContactLogic(1)SymbolPower Sequence Order Description NoteCase Case Note 2 Module case2 1VeeT 1st Module transmitter ground 3 2 LVTTL-O Tx_fault 3rd Module transmitter fault (N/A) 4 3 LVTTL-I Tx_disable 3rd Transmitter disable (N/A)4 4 LVTTL-I/O SDA 3rd 2-wire serial interface data line, same as MOD-DEF25 5 LVTTL-I/O SCL3rd 2-wire serial interface clock, same as MOD-DEF15 6Mod_ABS 3rd Module absent, connected to VeeT or VeeR in module 6 7 LVTTL-I RSO 3rd Rate select 0, optionally controls SFP+ receiver (N/A) 4 8 LVTTL-O Rx_LOS 3rd Receiver loss of signal indication (N/A)4 9LVTTL-IRS13rdRate select 1, optionally controls SFP+ transmitter (N/A)410 VeeR 1st Module receiver ground 311 VeeR 1stModule receiver ground312 CML-O RD- 3rdReceiver inverted data output13 CML-O RD+ 3rdReceiver non-inverted data output14 VeeR 1stModule receiver ground315 VccR 2ndModule receiver 3.3V supply16 VccT 2ndModule transmitter 3.3V supply17 VeeT 1stModule transmitter ground318 CML-I TD+ 3rdTransmitter non-inverted data output19 CML-I TD- 3rdTransmitter inverted data output20 VeeT 1stModule Transmitter Ground3 Notes:1. Labeling as Input (I) and Output (O) are from perspective of the module (cable connector)2. The case makes electrical contact to the host cage before any board edge contacts are made3. The module signal grounds, VeeR and VeeT, should be isolated from the module case4. Tx-fault, Tx_disable, rate select, and loss of signal functions are not implemented in passive copper cable assemblies5. SDA and SCL are the data and clock pins for the I2C interface to the EEPROM on board the module. The registers are defined in SFF-8472.6. Mod_ABS is an output pin to indicate if the module is present in the host port It is connected to ground in the module (cable connector)Installing and Removing 10Gig™ SFP Copper Cable AssembliesTo attach a cable assembly, remove the purple protective EMI cap. Then simply insert the connector end into the cage of the SFP+ host port in the active equipment. Make sure the cable is fully inserted and engaged.ATTENTION: Observe precautions for handling electrostatic sensitive electronic devices when installing this product. Ensure that you are properly grounded with a wrist strap or equivalent while installing10Gig™ SFP+ Copper Cables.To disengage, gently pull the latch release and the cable assembly will easily disengage the port. The Panduit® 10Gig™ SFP+ Direct Attached Copper Cable Assemblies have been designed to fit into high-density belly-to-belly faceplates.Cable ManagementThe weight of large bundles of SFP+ twin-axial cables can exert a significant force along the horizontal plane, and specifically on the host port of the active equipment. If the cable emerges from the rear of the connector at too sharp an angle, excess mechanical stress may be transmitted both along the cable and into the circuit board located inside the connector. Excessive side forces exerted by the cable can also misalign the plug in the equipment-mounted receptacle. These forces may degrade performance or even possibly damage the connector and lead to failure. It is important to observe and maintain proper cable bend radius and equally important to provide adequate and secure strain relief on the cable.In order to help maintain proper bend, it is recommended to pre-form the strain relief bend on the cable before installing. The minimum recommended bend radius is 5X the cable outside diameter (O.D.) for a single time bend and 10X the OD for repeated bends.Cable Wire Gauge O.D. Min. Bend Radius (r)30 AWG 4.1mm (0.16 in.) 20.5mm (0.80 in.)24 AWG 5.6mm (0.22 in.) 28.0mm (1.10 in.)To help manage the weight of bundled cable and ensure they do not sag over time, a cable manager or strain relief bar should be installed to support SFP+ Copper Cable Assemblies and provide strain reliefalong the horizontal plane. Strain relief bars facilitate the correct alignment of cable and connector intothe port, and help installers observe manufacturer and bend radius requirements of cable close to the connector. The strain relief bars also help keep cables routed clear from spaces directly behind server and switch equipment, reducing thermal resistance through the equipment and promote effective cooling and airflow. To ensure long-term reliability, it is recommended to use a rack with integral cable management features such as the Panduit® Net-Access™ Cabinets.Tak-Ty™ Hook and Loop Cable Ties should be used to bundle the cables together and tie them to the strain relief bars and cable managers. This should be done carefully to ensure the cables are firmly in place and will not move, but not so tight as to deform or stress the cable jacketing.Cable Installation Tips and Best PracticesThere are a few practical steps that can be taken during installation to optimize the effectiveness of the layout.▪For overhead cable routing, place the switches near the top of the racks▪For under floor cable routing, place the switches near the bottom of the racks▪Do not route SFP+ Cable Assemblies parallel to power cables, they should only cross at right angles▪Do not route cables in front of fans or air ventilation areas of the rack▪Do not kink cables▪Do not twist connectors▪Use Tak-Ty™ Hook and Loop Cable Ties to secure cables, do not use plastic cable tiesSlack ManagementStandard cables come in 1m (3.3 ft.) increments. Often installers will standardize on a small number of standard lengths to simplify the bill of material. One cannot always anticipate possible infrastructure obstacles on site so it is good practice to estimate long when defining cable lengths. Therefore, it is possible that there will be cable slack and this needs to be managed properly to ensure reliable long term performance. The slack in the cable should be shaped and looped so as not to violate bend radius. Slack or loops should be securely tied in place so they do not slip or sag over time.General Deployment Topology GuidelinesWithin a single 84 in. 45 RU cabinet, conservatively the longest connection will be 7 ft. or 2.1m to reach from the top U to the bottom and approximately 1.5 ft. or 0.45m to route to any port on either end. A 3m cable should be adequate to connect any two ports within a cabinet.84 inches =7 ft. = 2.1m Example cabinet with 2 top of rack switches (ToR) and 20 2U servers with Dual SFP+ NICs total of 40 SFP+ cables Conservatively, longest cable required to reach farthest port is 2.1 + 2.x 0.45 ≈ 3mExample of 3 cabinet Pod with 40 2 RU servers distributed over 3 cabinets with 2 ToR switches in center cabinet requires 80 SFP+ cables with longest cable of 4m Example of 5 cabinet Pod with 80 2 RU servers distributed over 5 cabinets with 4 ToR switches in center cabinet requires 160 SFP+ cables with longest cable of 5m10Gig™ SFP+ Copper Cable Assembly Installation Guidelines PN533BFor Instructions in Local Languagesand Technical Support: /resources/install_maintain.aspE-mail:***********************Phone:866-405-6654Using Middle of Row switching topology, an 8 cabinet row may be achieved with 7m cables. This has two switchcabinets in the center and 3 server cabinets on each side. If all switching were placed in a single center cabinet, a 9 cabinet row with 8 server cabinets may be covered. To enable longer row, fiber and SFP+ optical transceivers arerequired. A hybrid solution of Panduit ®10Gig™ SFP+copper for the inner cabinets and Panduit ®10Gig™ OM3 fiber to the outer cabinets will be the cost effective solution.。

PS中通道混合器的作用及使用简说先说一下通道亮度与颜色变化的关系：一般规律：在RGB颜色模式中，通道红——越亮，画面就越红(减绿);越暗就越绿(减红);通道绿——越亮，画面就越绿(减品);越暗就越品(减绿);通道蓝——越亮，画面就越蓝(减黄);越暗就越黄(减蓝);现在建一个大小合适的文档，填充中性灰颜色(H=0、S=0%、B=50%或R=G=B=128或#808080等)。
通道混和器的图层。
加全白蒙版，通道混和器就作用于整个某通道;加局部透明蒙版，通道混和器就只作用于某通道的局部透明区域。
在RGB颜色模式下，输出通道只有红(Alt+3)、绿(Alt+4)、蓝(Alt+5)。
在CMYK颜色模式下，输出通道只有青色(Alt+3)、洋红(Alt+4)、黄色(Alt+5)、黑色(Alt+6)。
通道混和器的面板中，红色百分比、绿色百分比、蓝色百分比是指原图通道相对应的通道红、通道绿、通道蓝参与计算的百分比。
比如，在修复通道时，往往是某个通道噪点太多，品质不高;相反，另一个通道的品质很好，色阶丰富、平滑、细腻。
这时，我们就会让品质好的通道，占更多的百分比参与计算，从而得到一个较好的新通道，将原来品质差的通道替换掉。
选择输出通道红(Alt+3)，这时面板参数计算得到的新通道就将替换原来的通道红;选择输出通道绿(Alt+4)，这时面板参数计算得到的新通道就将替换原来的通道绿;选择输出通道蓝(Alt+5)，这时面板参数计算得到的新通道就将替换原来的通道蓝;······规律1：如果通道混和器中，对某通道始终有等式成立：红色百分比%+绿色百分比%+蓝色百分比%=总计100%那么，该通道的中性灰的颜色就会保持不变。
见图2图2在人像调色中，人的肤色往往都比较接近中性灰，所以，就可以用这个办法，先大大改变背景和人物衣服的颜色，而人的肤色改变就很少。
在水墨画效果的调色中，也可以用这个办法，保证中性灰的颜色不变，而改变整个画面的色调等。
管道混合器安装要求
管道混合器的安装要求主要包括以下几个方面：
1. 安装位置：混合器应安装在管道上，位置要方便操作和维护。
同时，需要保证管道上游有足够的直管段作为混合室，以保证混合效果。
2. 安装方向：混合器外壳上通常有进口和出口标识，需要按照标识正确安装，确保介质可以顺利流经。
3. 安装支承：混合器需要通过支架或法兰连接来固定在管道上，以保证其稳定性和安全性。
4. 安装前准备：在安装之前，需要对管道进行清洗和除杂处理，确保管道内部没有杂质或污垢，以免影响混合效果。
同时，也要检查管道的尺寸和材质是否符合混合器的要求。
5. 密封：混合器的连接部分需要进行密封处理，以防止漏液或逆流现象的发生。
常用的密封材料有橡胶垫圈、填料和密封胶等。
6. 排气：在安装完成后，需要对混合器进行排气处理，以确保管道内没有气体阻塞。
7. 调试：安装完成后，需要进行调试和测试，确保混合器的工作效果和参数符合设计要求。
