DAC and AOC are common cabling solutions for data networking and are usually used for high-speed, high-reliability interconnection and transmission required by data centers, high-performance computers, and large-capacity storage devices. Both of their ends have cable assemblies with factory-terminated transceivers, which are connected to fixed ports only. Besides, DAC and AOC cables can be manufactured in different lengths to support different transmission data rates, such as 10G SFP DAC\/AOC cable, 25G AOC cable, 40G DAC cable, and 100G AOC cable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pros-and-cons-of-dac-cable\"><span class=\"ez-toc-section\" id=\"Pros_and_Cons_of_DAC_Cable\"><\/span><strong>Pros and Cons of DAC Cable\u00a0<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pros-of-direct-attach-copper-cable\"><span class=\"ez-toc-section\" id=\"Pros_of_Direct_Attach_Copper_Cable\"><\/span>Pros of Direct Attach Copper Cable<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><b>More Cost-effective<\/b>&#8212; Generally speaking, the price of copper cables is much lower than that of optical fibers. The cost of passive copper cables is 2 to 5 times cheaper than fiber cables of the same length. Therefore, the use of high-speed cables will also reduce the cabling costs of the entire data center.<\/p>\n\n\n\n<p><b>Lower Power Consumption<\/b>&#8212; High-speed DAC (<a href=\"https:\/\/www.fibermall.com\/store-16564-direct-attach-cables.htm\" target=\"_blank\" rel=\"noopener\">direct attach cable<\/a>) consumes less power(the power consumption is almost zero) since passive cables do not require a power supply. The power consumption of active copper cables is generally around 440mW. If you use direct attach copper cables instead of AOC fiber cables, you can save hundreds of thousands of kilowatts of electrical power.<\/p>\n\n\n\n<p><b>It is more durable<\/b>&#8211;It is designed with a seamless connection form of optical module and optical cable, which reduces the cost and ensures that the optical port is not exposed to dust and other pollutants. Therefore, DAC is less susceptible to damage.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-cons-of-direct-attach-copper-cable\"><span class=\"ez-toc-section\" id=\"Cons_of_Direct_Attach_Copper_Cable\"><\/span>Cons of\u00a0Direct Attach Copper Cable<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>One of the disadvantages of DAC cable is that it is heavier and bulkier than AOCs. In addition, it is more susceptible to the effect of\u00a0electromagnetic\u00a0interference and attenuation over longer distances due to the electrical signals transmitted between both ends.\u00a0\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pros-and-cons-of-aoc-cable\"><span class=\"ez-toc-section\" id=\"Pros_and_Cons_of_AOC_Cable\"><\/span><b>Pros and Cons of AOC Cable<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pros-of-aoc\"><span class=\"ez-toc-section\" id=\"Pros_of_AOC\"><\/span>Pros of AOC<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><b>Lighter weight<\/b>-An active optical cable is composed of two optical transceivers and a fiber optic patch cable, whose weight is only a quarter of the direct attach copper cable, and the bulk is about half of the copper cable. <\/p>\n\n\n\n<p><b>Longer distances-<\/b>AOC fiber can provide a greater and longer transmission reach of up to 100-300m due to its better heat dissipation in the computer room\u2019s wiring system and smaller bending radius of optical cable.<\/p>\n\n\n\n<p><b>More Reliable<\/b>&#8211; Active optical cable is less vulnerable to electromagnetic interference since optical fiber is a kind of dielectric that can sustain a static electric field within it.

Generally speaking, the distance between a ToR and a server NIC(Network Interface Card) is less than 5 meters. In this situation, DAC cable is more advantageous than AOC cables in the respect of cost, power consumption, and heat dispersion. Thus, DAC is a preferred option for IDC interconnect systems.

Some time ago, FiberMall released the 200G QSFP DD PSM8 optical module, marking the basic completion of the 200G low-cost data center internal parallel optical interconnection solution based on NRZ modulation, and also symbolizing the company&#8217;s leading position in 200G solutions. Different from the 400G solution advocated by the industry, FiberMall insists on the 200G data center solution and can provide customers with one-stop services and answers.<\/p>\n\n\n\n<p>The following mainly analyzes the characteristics and application fields of InfiniBand technology among\u00a0current switches based on the development process of the supercomputing center at this stage.

These five technologies occupy an important market share, among which InfiniBand and high-performance Ethernet occupy an absolute leading position.<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe1-300x155.png\" alt=\"top 500 interconnect trend\" class=\"wp-image-2038\" style=\"width:800px\" width=\"800\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe1-300x155.png 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe1.png 548w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/figure>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">The interconnection technology of supercomputing centers is developing towards higher bandwidth, lower latency, lower power consumption, and denser interconnection ports. InfiniBand interconnection technology is currently the first choice for high-performance storage interconnection solutions, precisely because it meets the needs of large bandwidth and low latency.<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">InfiniBand is a unified interconnect fabric that handles storage I\/O, network I\/O, and inter-process communication. It can interconnect disk arrays, SANs, LANs, servers, and clustered servers, provide high-bandwidth, low-latency transmission over relatively short distances, support redundant I\/O channels in single or multiple interconnected networks, and keep your data center running in the event of a partial failure. Especially in the future when the traffic inside the HPC data center will increase significantly, as a network connection technology is applied between servers, InfiniBand will have a broader space for development.<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">The following figure shows the product roadmap of InfiniBand.<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe2-300x169.png\" alt=\"the product roadmap of InfiniBand\" class=\"wp-image-2040\" style=\"width:800px\" width=\"800\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe2-300x169.png 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe2.png 594w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-infiniband-network-technology-trends\"><span class=\"ez-toc-section\" id=\"InfiniBand_Network_Technology_Trends\"><\/span>InfiniBand Network Technology Trends<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">The interconnection interface of InfiniBand has gradually transitioned from the copper interconnection to the parallel optical interconnection technology dominated by VCSEL lasers. In contrast, the optical interconnection technology has more advantages:<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">1. Compared with copper cables, optical fiber has low attenuation and a longer transmission distance of up to 100 meters.<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">2. Strong anti-interference, zero packet loss rate, no matter how complicated the strong electricity coiled around the fiber is, the transmission speed is always consistent.<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">3. The service life is very long and the compatibility is high. Most of the optical fibers on the market can be used for 10 years or even longer, which the copper cable network cable can not compare.<\/span><\/p>\n\n\n\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">The port form factor&nbsp;of the interconnect technology of the supercomputing center is developing towards a higher working bandwidth.

The size of the QSFP DD package is basically the same as that of the QSFP28 package, but its length is slightly longer (with a dual-row gold finger connector), and its electrical interface supports 8x25Gbps NRZ (200G) and 8x28GBd PAM4 (400G). Therefore, on the space interface of the same density, its bandwidth is 2 to 4 times the working bandwidth of the 100G QSFP28 optical module. At the same time, the QSFP DD also has equipment that is backward compatible with the QSFP28 interface, which plays a role in protecting investors.<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe3-300x79.png\" alt=\"qsfp-dd optical transceiver\" class=\"wp-image-2043\" style=\"width:800px\" width=\"800\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe3-300x79.png 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe3-1024x271.png 1024w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe3-768x203.png 768w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/\u56fe3.png 1071w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-application-of-200g-qsfp-dd-aoc-in-infiniband\"><span class=\"ez-toc-section\" id=\"Application_of_200G_QSFP_DD_AOC_in_InfiniBand\"><\/span>Application of 200G QSFP DD AOC in InfiniBand<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Unlike Ethernet, which is used for high-level network communication, InfiniBand is mainly used for low-level server-side input\/output performance tasks, and AOC is generally used for connection between devices. In addition, considering the problem that signals are easily distorted in ultra-high-speed optical fiber transmission, InfiniBand transmits data signals in a differential manner in optical fibers and adds filters at the signal receiving end to filter out signal noise, fully ensuring the signal integrity of the connected network.<\/p>\n\n\n\n<p>FiberMall 200G QSFP DD multimode optical modules and 200G QSFP-DD 1- 100m AOC products use self-developed and packaged COB (Chip on Board) technology. The products can provide a new generation of optical interconnect solutions with low cost, low power consumption, high density, and high speed. The product integrates two optical engines in a limited and compact space, providing 8-way 25G high-speed data channels. Its excellent heat dissipation design solves the problem of temperature accumulation. The total power consumption is less than 3.5W at 0~70 degrees celsius at full temperature. The optical interface adopts MPO24 Interface (16 fibers), and the multi-mode OM4 fiber can guarantee a working distance of 1-100 meters.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/4-e1652408627392-300x232.jpg\" alt=\"FiberMall's 200G QSFP DD AOC\" class=\"wp-image-2044\" style=\"width:600px\" width=\"600\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/4-e1652408627392-300x232.jpg 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/4-e1652408627392-768x593.jpg 768w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/04\/4-e1652408627392.jpg 1000w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 10pt;\">FiberMall&#8217;s 200G QSFP DD AOC<\/span><\/strong><\/p>\n\n\n\n<p>Mr. Gilad Shainer, vice president of marketing at Mellanox, a well-known InfiniBand network solutions company, said: &#8220;With the increasing development of machine learning and HPC cloud, customers&#8217; requirements for network performance are demanding.

When there are few transmission requirements for the data center, the DAC cable solution is suggested as a better internet cable solution for the interconnection between the server and the switch within 5m\/10m, while the AOC fiber solution is perfect for the interconnection between switches and the switches. By all means, it is unnecessary to analyze which is the better solution, that is AOC cable is always your first for performance is way much more important than cost if budget is never your concern.<\/p>\n<style>\r\n\r\n        .lwrp.link-whisper-related-posts{\r\n            \r\n            margin-top: 40px;\nmargin-bottom: 30px;\r\n        }\r\n        .lwrp .lwrp-title{\r\n            \r\n            \r\n        }\r\n        .lwrp .lwrp-description{\r\n            \r\n            \r\n\r\n        }\r\n        .lwrp .lwrp-list-container{\r\n        }\r\n        .lwrp .lwrp-list-multi-container{\r\n            display: flex;\r\n        }\r\n        .lwrp .lwrp-list-double{\r\n            width: 48%;\r\n        }\r\n        .lwrp .lwrp-list-triple{\r\n            width: 32%;\r\n        }\r\n        .lwrp .lwrp-list-row-container{\r\n            display: flex;\r\n            justify-content: space-between;\r\n        }\r\n        .lwrp .lwrp-list-row-container .lwrp-list-item{\r\n            width: calc(100% - 20px);\r\n        }\r\n        .lwrp .lwrp-list-item:not(.lwrp-no-posts-message-item){\r\n            \r\n            list-style: decimal;\r\n        }\r\n        .lwrp .lwrp-list-item img{\r\n            max-width: 100%;\r\n            height: auto;\r\n        }\r\n        .lwrp .lwrp-list-item.lwrp-empty-list-item{\r\n            background: initial !important;\r\n        }\r\n        .lwrp .lwrp-list-item .lwrp-list-link .lwrp-list-link-title-text,\r\n        .lwrp .lwrp-list-item .lwrp-list-no-posts-message{\r\n            \r\n                \r\n        }\r\n        @media screen and (max-width: 480px) {\r\n            .lwrp.link-whisper-related-posts{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-title{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-description{\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-list-multi-container{\r\n                flex-direction: column;\r\n            }\r\n            .lwrp .lwrp-list-multi-container ul.lwrp-list{\r\n                margin-top: 0px;\r\n                margin-bottom: 0px;\r\n                padding-top: 0px;\r\n                padding-bottom: 0px;\r\n            }\r\n            .lwrp .lwrp-list-double,\r\n            .lwrp .lwrp-list-triple{\r\n                width: 100%;\r\n            }\r\n            .lwrp .lwrp-list-row-container{\r\n                justify-content: initial;\r\n                flex-direction: column;\r\n            }\r\n            .lwrp .lwrp-list-row-container .lwrp-list-item{\r\n                width: 100%;\r\n            }\r\n            .lwrp .lwrp-list-item:not(.lwrp-no-posts-message-item){\r\n                \r\n                \r\n            }\r\n            .lwrp .lwrp-list-item .lwrp-list-link .lwrp-list-link-title-text,\r\n            .lwrp .lwrp-list-item .lwrp-list-no-posts-message{\r\n                \r\n                    \r\n            }\r\n        }<\/style>\r\n<div id=\"link-whisper-related-posts-widget\" class=\"link-whisper-related-posts lwrp\">\r\n            <h3 class=\"lwrp-title\">Related Posts<\/h3>    \r\n        <div class=\"lwrp-list-container\">\r\n                                            <ul class=\"lwrp-list lwrp-list-single\">\r\n                    <li class=\"lwrp-list-item\"><a href=\"https:\/\/www.fibermall.com\/news\/us-fcc-launches-5g-construction-fund.htm\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">US.
