BiDi SFP modules let you use just one fiber for both directions. This saves fiber and makes your network simpler.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Can you mix SFP and BiDi SFP modules in the same network?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can use both types in the same network, but not on the same link. Each link must use either two SFP modules or a matched pair of BiDi SFP modules. Mixing them on one link will not work.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Which module should you choose if fiber is limited?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You should pick BiDi SFP modules. They let you send and receive data on a single fiber. This helps you double your network capacity without adding more cables.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Are BiDi SFP modules compatible with all switches?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not all switches support BiDi SFP modules. You need to check your switch\u2019s specifications. Some switches require specific brands or models for BiDi SFP compatibility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Do SFP and BiDi SFP modules support the same speeds and distances?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Both SFP and BiDi SFP modules support similar data rates and distances. You can find options for 1G, 10G, and even higher speeds in both types. Always check the specs for your needs.<\/p>\n\n\n\n<script src=\"https:\/\/cdn.mylandingpages.co\/widgets\/platform\/platform.widget.js\" async=\"true\"><\/script>","protected":false},"excerpt":{"rendered":"<p>So s\u00e1nh SFP v\u00e0 SFP BiDi: nh\u1eefng \u0111i\u1ec3m kh\u00e1c bi\u1ec7t ch\u00ednh, y\u00eau c\u1ea7u c\u00e1p quang, kh\u1ea3 n\u0103ng t\u01b0\u01a1ng th\u00edch v\u00e0 c\u00e1c tr\u01b0\u1eddng h\u1ee3p s\u1eed d\u1ee5ng ph\u00f9 h\u1ee3p nh\u1ea5t \u0111\u1ec3 gi\u00fap b\u1ea1n l\u1ef1a ch\u1ecdn \u0111\u00fang m\u00f4-\u0111un SFP cho m\u1ea1ng c\u1ee7a m\u00ecnh.<\/p>","protected":false},"author":1,"featured_media":5765,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[26],"class_list":["post-5768","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-knowledge-center","tag-optics-transceivers"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/posts\/5768","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/comments?post=5768"}],"version-history":[{"count":4,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/posts\/5768\/revisions"}],"predecessor-version":[{"id":11310,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/posts\/5768\/revisions\/11310"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/media\/5765"}],"wp:attachment":[{"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/media?parent=5768"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/categories?post=5768"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/resourceslp.szlogic.cn\/vi\/wp-json\/wp\/v2\/tags?post=5768"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
