In fact, there are only a few optical module manufacturers in the world that have a complete production system, such as Finisar, AVAGO, etc. Both brand owners and third-party manufacturers have asked specialized optical module manufacturers (OEM, Original Equipment Manufacturer) to make optical modules according to the market protocols and standards. Therefore, the optical module made by OEM is the same as the product sold to other brands. So should we choose the original brands optical module or the third-party compatible optical module?<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Branded modules will set a special code so that customers can only use the brand&#8217;s supporting equipment, while compatible modules crack the code settings inside and can be compatible with a variety of devices. Branded modules are relatively high priced and of good quality, while compatible optical modules are cheap and cost-effective.<\/span><\/p>\n<p>&nbsp;<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_76 ez-toc-wrap-left counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.fibermall.com\/blog\/compatible-vs-original-optical-transceivers.htm\/#_1_Introduction_of_the_original_brand_optical_transceiver\" >\u00a01.

The optical module brands currently known to the public are Cisco, HW, H3C, HPE,\u00a0Dell, etc. However, third-party module vendors can independently achieve decoding and writing codes through the analysis of the module, an OEM to add the module code is basically only one or a few, excellent compatible module vendors can simultaneously master the code of multiple OEMs, making it much easier and more convenient for customers to purchase and install, and the cost is also lower than that of branded optical modules.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><img fetchpriority=\"high\" decoding=\"async\" class=\" wp-image-1239 aligncenter\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/brands-optical-module.png\" alt=\"brands optical module\" width=\"652\" height=\"123\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/brands-optical-module.png 906w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/brands-optical-module-300x57.png 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/brands-optical-module-768x145.png 768w\" sizes=\"(max-width: 652px) 100vw, 652px\" \/><\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"_2_Is_the_compatible_optical_transceiver_a_better_choice\"><\/span><span style=\"font-size: 12pt;\"><b><\/b><span style=\"font-size: 14pt;\"><strong><b>\u00a02.

Be aware that what fits your equipment is not always a branded original optical module. Third-party compatible modules are not only compatible with any available branded equipment, but also do not require the expensive brand price, while providing a variety of options for these types of networks. Currently, FiberMall is able to offer both branded and standard compatible optical modules to meet the needs of different customers.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><img decoding=\"async\" class=\" wp-image-1240 aligncenter\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/Fiber-Mall-optical-transceiver-compatibility-testing.jpg\" alt=\"FiberMall optical transceiver compatibility testing\" width=\"629\" height=\"343\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/Fiber-Mall-optical-transceiver-compatibility-testing.jpg 1160w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/Fiber-Mall-optical-transceiver-compatibility-testing-300x163.jpg 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/Fiber-Mall-optical-transceiver-compatibility-testing-1024x558.jpg 1024w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/Fiber-Mall-optical-transceiver-compatibility-testing-768x418.jpg 768w\" sizes=\"(max-width: 629px) 100vw, 629px\" \/><\/span><\/p>\n<p style=\"text-align: center;\"><strong><span style=\"font-size: 10pt;\">FiberMall optical transceiver compatibility testing<\/span><\/strong><\/p>\n<p>&nbsp;<\/p>\n<ul style=\"list-style-type: circle;\">\n<li><span style=\"font-size: 12pt;\"><strong><b>\u00a0<\/b><\/strong><strong><b>More competitive price<\/b><\/strong><\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 12pt;\"><strong><b>\u00a0<\/b><\/strong><\/span><\/p>\n<p><span style=\"font-size: 12pt;\">The brand effect is a very common phenomenon.

The SFF-8472 standard is a key factor to determine whether the quality and compatibility of third-party optical modules are passing. It was developed by the SFF committee to define the <strong>Data Diagnostic Monitoring Interface (DDMI)<\/strong> for optical modules, which can help us understand the operating parameters of optical modules in real-time.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-1242 aligncenter\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/DDMI-of-compatibel-transceiver.png\" alt=\"DDMI of compatibel transceiver\" width=\"595\" height=\"376\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/DDMI-of-compatibel-transceiver.png 1147w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/DDMI-of-compatibel-transceiver-300x190.png 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/DDMI-of-compatibel-transceiver-1024x648.png 1024w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2021\/07\/DDMI-of-compatibel-transceiver-768x486.png 768w\" sizes=\"(max-width: 595px) 100vw, 595px\" \/><\/span><\/p>\n<p style=\"text-align: center;\"><strong><span style=\"font-size: 10pt;\">DDMI data\u00a0board\u00a0example<\/span><\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-size: 12pt;\">The MCU chip in the PCBA of the optical module has an EEPROM area dedicated to storing information about the optical module.

modules meeting this standard can be guaranteed. In addition, we should pay attention to the following three points: check whether the optical module matches the port of the network equipment; ensure that the wavelength of the optical module used at both ends matches; and the optical module at both ends must use the correct network patch cable or fiber optic patch cable when making connections.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"_4_Summary\"><\/span><span style=\"font-size: 12pt;\"><b><\/b><span style=\"font-size: 14pt;\"><strong><b>\u00a04. Summary<\/b><\/strong><\/span><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&nbsp;<\/p>\n<p><span style=\"font-size: 12pt;\">The quality of the optical module can directly affect the transmission effect of the optical link. Although the quality of the original optical module is good, its price is very expensive. At present, the compatible optical modules provided by many third-party suppliers can be compared with the original optical modules, and the price is very advantageous, which can help users save a lot of costs. <strong>FiberMall<\/strong> is a professional optical module supplier. We have a special process to test the compatibility of optical modules, which is to ensure that every optical module is 100% compatible. We can provide switches compatible with network equipment of major brands, such as HW, H3C, Cisco, HPE, Dell, Juniper, ZTE, etc., with favorable prices and sufficient inventory.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/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\/blog\/return-loss-10g-sfp.htm\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">How to improve the return loss of 10G SFP+<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/www.fibermall.com\/blog\/infiniband-copper-cable.htm\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">Unlocking the Power of Infiniband: A Deep Dive into Copper Cables and Direct-Attach Solutions<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/www.fibermall.com\/blog\/mtp-fiber-connector.htm\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">Unlocking the Potential of MTP Fiber Connectors in Modern Data Centers<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/www.fibermall.com\/blog\/optical-cable.htm\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">Everything You Need to Know About Fiber Optic Cable: A Comprehensive Guide<\/span><\/a><\/li><li class=\"lwrp-list-item\"><a href=\"https:\/\/www.fibermall.com\/blog\/800g-qsfp-dd.htm\" class=\"lwrp-list-link\"><span class=\"lwrp-list-link-title-text\">Everything You Need to Know About 800g QSFP-DD Optical Transceivers<\/span><\/a><\/li>                <\/ul>\r\n                        <\/div>\r\n<\/div>","protected":false},"excerpt":{"rendered":"<p>&nbsp; With the rapid development of the communication industry, the demand for optical modules is increasing rapidly, so there are many third-party optical modules in the market.
