Attempting to use it over SMF will fail immediately or cause severe errors. Always match the <strong>optical module type<\/strong> to the fiber type.<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: Can I use an LR4 transceiver over multimode fiber?<\/strong><br\/><strong>A: No.<\/strong> LR4 requires single-mode fiber (OS2). Using it over MMF will not achieve the required distance or performance.<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: What is the maximum distance for QSFP28 LR4?<\/strong><br\/><strong>A:<\/strong> The standard specification for QSFP28 100G LR4 is <strong>up to 10 kilometers<\/strong> over OS2 single-mode fiber. Ensure your optical budget (link loss) supports the required distance.<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: Are SR4 and LR4 transceivers interoperable?<\/strong><br\/><strong>A:<\/strong> No, they are not directly interoperable with each other. An SR4 module must connect to another SR4 module over MMF. An LR4 module must connect to another LR4 module over SMF. They use fundamentally different optical technologies and fiber paths.<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: What about ER4 or ZR4 modules?<\/strong><br\/><strong>A:<\/strong> These are variants for even longer distances than LR4. ER4 typically reaches ~40km, and ZR4 reaches ~80km. They consume significantly more power and cost more than LR4. LR4 (10km) covers the vast majority of campus and metro DCI needs.<\/p><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" ><strong>\u27a4 See Also<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resources.l-p.com\/ru\/products\/100g-lr4-transceiver-long-distance-high-speed-network-guide\/\">Understanding the 100G LR4 Transceiver for Modern Networks<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resources.l-p.com\/ru\/products\/qsfp28-100g-sr4-transceivers\/\">Unlock High-Speed LINK-PP QSFP28 100G SR4 Transceiver \u2013 LQ-M85100-SR4C<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resources.l-p.com\/ru\/knowledge-center\/100g-optical-transceiver-form-factors-guide\/\">A Comprehensive Guide to 100G Optical Transceiver Module Form Factors<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resources.l-p.com\/ru\/products\/link-pp-100g-transceivers-connectivity\/\">Why Choose LINK-PP 100G Transceivers for High-Speed Connectivity<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Compare QSFP28 100G SR4 vs LR4 to choose the right 100G transceiver for your network based on distance, fiber type, connectors, and budget.<\/p>","protected":false},"author":1,"featured_media":5784,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[28],"tags":[13],"class_list":["post-5787","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-products","tag-100g-modules"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/posts\/5787","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/comments?post=5787"}],"version-history":[{"count":4,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/posts\/5787\/revisions"}],"predecessor-version":[{"id":11316,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/posts\/5787\/revisions\/11316"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/media\/5784"}],"wp:attachment":[{"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/media?parent=5787"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/categories?post=5787"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/resources.l-p.com\/ru\/wp-json\/wp\/v2\/tags?post=5787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
