These are separate passive components.<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: Can CWDM4 modules work with BiDi technology?<\/strong><br\/><strong>A\uff1a<\/strong> No. Standard CWDM4 uses two fibers (Tx and Rx). 100G BiDi solutions (like QSFP28 BiDi) exist but use different wavelengths on a <em>\u304a\u5ba2\u69d8\u306e<\/em> fiber pair for potentially longer reaches (e.g., 10km, 20km, 40km).<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: Is CWDM4 hot-pluggable?<\/strong><br\/><strong>A\uff1a<\/strong> Yes, like most QSFP28 modules, CWDM4 transceivers are designed for hot-pluggability, allowing installation and removal without powering down the host equipment.<\/p><\/li><li><p style=\"margin: 0px;\"><strong>Q: Why choose LINK-PP CWDM4 modules?<\/strong><br\/><strong>A: LINK-PP<\/strong> LINK-PP \u306f\u3001 <strong>MSA-compliant, high-performance, reliable 100G CWDM4 optics<\/strong> backed by quality assurance and significant cost savings compared to OEM options, making them an intelligent choice for scaling your optical network.<\/p><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" ><strong>\u307e\u305f\u53c2\u7167<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resourceslp.szlogic.cn\/ja\/knowledge-center\/100g-qsfp28-optical-transceivers-selection-guide\/\">100G QSFP28\u5149\u30c8\u30e9\u30f3\u30b7\u30fc\u30d0\u30fc\u3092\u63a2\u7d22\uff1aSR4\u3001LR4\u3001CWDM4\u3001PSM4\u306a\u3069<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resourceslp.szlogic.cn\/ja\/knowledge-center\/psm4-vs-cwdm4-which-optical-transceiver-for-your-network\/\">PSM4 vs.\u00a0CWDM4: What is the differences?<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resourceslp.szlogic.cn\/ja\/knowledge-center\/100g-single-lambda-vs-4-channel-optical-modules-comparison\/\">100G\u30b7\u30f3\u30b0\u30eb\u30e9\u30e0\u30c0\u65b9\u5f0f\u30684\u6ce2\u9577\u65b9\u5f0f\u306e\u5149\u30e2\u30b8\u30e5\u30fc\u30eb\u306e\u4e3b\u306a\u9055\u3044<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a target=\"_blank\" rel=\"\" href=\"https:\/\/resourceslp.szlogic.cn\/ja\/knowledge-center\/100g-optical-transceiver-form-factors-guide\/\">100G\u5149\u30c8\u30e9\u30f3\u30b7\u30fc\u30d0\u30fc\u306e\u30d5\u30a9\u30fc\u30e0\u30d5\u30a1\u30af\u30bf\uff1aQSFP28\u3001CFP\u3001CFP2\u3001CFP4\uff1f<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>QSFP28 100G CWDM4\u30c8\u30e9\u30f3\u30b7\u30fc\u30d0\u306f\u3001\u6700\u59272km\u306e\u8ddd\u96e2\u3067\u30b3\u30b9\u30c8\u52b9\u7387\u3068\u9ad8\u6027\u80fd\u3092\u4e21\u7acb\u3057\u305f100\u30ae\u30d3\u30c3\u30c8\u30a4\u30fc\u30b5\u30cd\u30c3\u30c8\u63a5\u7d9a\u306e\u696d\u754c\u6a19\u6e96\u30bd\u30ea\u30e5\u30fc\u30b7\u30e7\u30f3\u3067\u3059\u3002 <\/p>","protected":false},"author":1,"featured_media":5402,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[13],"class_list":["post-5404","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-knowledge-center","tag-100g-modules"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/posts\/5404","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/comments?post=5404"}],"version-history":[{"count":4,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/posts\/5404\/revisions"}],"predecessor-version":[{"id":11244,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/posts\/5404\/revisions\/11244"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/media\/5402"}],"wp:attachment":[{"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/media?parent=5404"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/categories?post=5404"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/ja\/wp-json\/wp\/v2\/tags?post=5404"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
