Comme la m\u00e9thode A, il utilise des connecteurs de type A key-up\/key-down, et comme la m\u00e9thode B, les deux extr\u00e9mit\u00e9s peuvent \u00eatre attach\u00e9es \u00e0 des cordons de raccordement duplex AB droits. La diff\u00e9rence r\u00e9side dans le retournement de polarit\u00e9 de la fibre, qui est cr\u00e9\u00e9 par des paires crois\u00e9es dans le c\u00e2ble de r\u00e9seau MPO lui-m\u00eame : P1 (Tx) arrive \u00e0 P2 (Rx) \u00e0 l&#039;extr\u00e9mit\u00e9 oppos\u00e9e et vice versa, P3 et P4 sont crois\u00e9s de la m\u00eame mani\u00e8re et ainsi de suite.<\/span><span data-ccp-props=\"{&quot;335559739&quot;:420}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Cette m\u00e9thode n\u00e9cessite une planification plus approfondie de la gestion de la polarit\u00e9 des fibres et peut \u00e9galement \u00eatre probl\u00e9matique pour les signaux parall\u00e8les par opposition au duplex. Par exemple, une application 40G ou 100G \u00e0 huit fibres n&#039;est pas prise en charge par un c\u00e2ble r\u00e9seau \u00e0 paires crois\u00e9es \u00e0 12 fibres qui d\u00e9finirait P1-P4 comme transmission et P9 \u00e0 P12 comme r\u00e9ception. \u00c0 mesure que l&#039;\u00e9volutivit\u00e9 du r\u00e9seau \u00e0 haut d\u00e9bit devient de plus en plus importante, cette limitation prend \u00e9galement de l&#039;importance.<\/span><span data-ccp-props=\"{&quot;335559739&quot;:420}\">\u00a0<\/span><\/p>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-19795 size-full aligncenter\" src=\"https:\/\/www.precisionot.com\/wp-content\/uploads\/FiberPolarityBlogGraphics3.webp\" alt=\"Polarit\u00e9 de la fibre de type C\" width=\"675\" height=\"284\" srcset=\"https:\/\/www.precisionot.com\/wp-content\/uploads\/FiberPolarityBlogGraphics3.webp 675w, https:\/\/www.precisionot.com\/wp-content\/uploads\/FiberPolarityBlogGraphics3-300x126.webp 300w, https:\/\/www.precisionot.com\/wp-content\/uploads\/FiberPolarityBlogGraphics3-18x8.webp 18w, https:\/\/www.precisionot.com\/wp-content\/uploads\/FiberPolarityBlogGraphics3-600x252.webp 600w, https:\/\/www.precisionot.com\/wp-content\/uploads\/FiberPolarityBlogGraphics3-64x27.webp 64w\" sizes=\"(max-width: 675px) 100vw, 675px\" \/><\/figure>\n<\/div>\n\n<p><img \/><strong>Conclusion<\/strong><\/p>\n\n<p><a class=\"Hyperlink SCXW141129459 BCX0\" href=\"https:\/\/www.fiercetelecom.com\/broadband\/14m-us-businesses-now-connected-fiber-vertical-systems-group#:~:text=Enterprise%20fiber%20connectivity%20in%20the%20U.S.%20ramped%20up%20in%202022%2C%20reaching%20more%20than%201.4%20million%20commercial%20buildings%20and%20data%20centers%20in%202022\" target=\"_blank\" rel=\"noreferrer noopener\"><span class=\"TextRun Underlined SCXW141129459 BCX0\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"none\"><span class=\"NormalTextRun SCXW141129459 BCX0\" data-ccp-charstyle=\"Hyperlink\">La connectivit\u00e9 fibre optique continue de monter en puissance<\/span><\/span><\/a><span class=\"TextRun SCXW141129459 BCX0\" lang=\"EN-US\" xml:lang=\"EN-US\" data-contrast=\"auto\"><span class=\"NormalTextRun SCXW141129459 BCX0\">, faisant f<\/span><span class=\"NormalTextRun SCXW141129459 BCX0\">iber p<\/span><span class=\"NormalTextRun SCXW141129459 BCX0\">gestion de la polarit\u00e9<\/span><span class=\"NormalTextRun SCXW141129459 BCX0\"> plus important que jamais<\/span><span class=\"NormalTextRun SCXW141129459 BCX0\">.\u00a0 <\/span><span class=\"NormalTextRun SCXW141129459 BCX0\">Alors que la polarit\u00e9 de la fibre<\/span> <span class=\"NormalTextRun SCXW141129459 BCX0\">\u00e0 l&#039;\u00e8re multifibre est un sujet complexe, les principes de base qui s&#039;appliquent \u00e0 des applications simples continuent de servir de blocs de construction pour cr\u00e9er des solutions de r\u00e9seau durables.
