Einfacher ausgedr\u00fcckt: Der kleinste zul\u00e4ssige Radius, der die optische Faser biegen kann, ohne sie zu besch\u00e4digen, zu knicken oder ihre Lebensdauer zu verk\u00fcrzen, wird als Biegeradius bezeichnet.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/tse1-mm.cn.bing.net\/th\/id\/R-C.aec65f338eb16593465c2f0e9f40e021?rik=H8lcTnK2asRB3g&amp;riu=http%3a%2f%2fwww.fiber-optic-transceiver-module.com%2fwp-content%2fuploads%2f2015%2f12%2fBend-Insensitive-Fiber.jpg&amp;ehk=mgdnlHGaaVmBa6hhXkRHGGLBmkRVz63RVmHyWljEkks%3d&amp;risl=&amp;pid=ImgRaw&amp;r=0\"><\/p>\n<p id=\"uec208a6d\" class=\"ne-p\"><span class=\"ne-text\">Verschiedene optische Fasern haben unterschiedliche Eigenschaften und unterschiedliche physikalische Strukturen, weshalb der zul\u00e4ssige Biegeradius zwischen optischen Fasern unterschiedlich ist. In der Regel haben Glasfasern einen bestimmten Mindestbiegeradius. Es wird jedoch empfohlen, den minimalen Biegeradius etwa 10-mal kleiner als den Au\u00dfendurchmesser der optischen Faser zu halten. Daher sollte der Biegeradius eines 4mm-Glasfaserkabels nicht weniger als 40mm betragen.<\/span><\/p>\n<\/div>\n<div class=\"lake-content\">\n<h3 id=\"RxL3c\" class=\"fusion-responsive-typography-calculated\" style=\"--fontsize: 28; line-height: 1.36; --minfontsize: 28;\" data-fontsize=\"28\" data-lineheight=\"38.08px\"><span class=\"ne-text\">Standard Mindestbiegeradius<\/span><\/h3>\n<p id=\"u5fff204c\" class=\"ne-p\"><span class=\"ne-text\">In<\/span> <a class=\"ne-link\" href=\"https:\/\/www.itu.int\/rec\/T-REC-G.657\/en\" target=\"_blank\" rel=\"noopener\" data-href=\"https:\/\/www.itu.int\/rec\/T-REC-G.657\/en\" data-><span class=\"ne-text\">ITU-T-Normen<\/span><\/a><span class=\"ne-text\">Der minimale Biegeradius der G.657A2-Glasfaser wird mit 7,5 mm empfohlen.

Der minimale Biegeradius der G657A2-Glasfaser bezieht sich darauf, dass die zus\u00e4tzliche D\u00e4mpfung, gemessen bei 1550nm\/1625nm, wenn sich das Glasfaserkabel in einer losen Windung mit einem Radius von 7,5 mm befindet, 0,5 dB\/1,0 dB nicht \u00fcberschreiten darf.<\/span><\/p>\n<p id=\"uc32dc09c\" class=\"ne-p\"><span class=\"ne-text\">Der minimale Biegeradius der G652D-Glasfaser bezieht sich darauf, dass die Glasfaser f\u00fcr 100 Windungen mit einem Radius von 30 mm locker gewickelt ist und die bei 1625 nm gemessene zus\u00e4tzliche D\u00e4mpfung 0,1 dB nicht \u00fcberschreitet.<\/span><\/p>\n<p id=\"u3216fd28\" class=\"ne-p\"><span class=\"ne-text\">Der zus\u00e4tzliche Verlust, der durch die Biegung von Glasfasern mit einem Biegeradius, der viel gr\u00f6\u00dfer als ihr Durchmesser ist, verursacht wird, wird als Makrobiegeverlust bezeichnet.

class=\"ne-text\">Aus den Testergebnissen geht hervor, dass das ankommende optische FTTH-Kabel (G.657A2) eine h\u00f6here Biegefestigkeit aufweist als das Glasfaser-Pigtailkabel (G.652D), insbesondere bei kleinen Biegeradien.<\/span><\/p>\n<\/div>\n<div class=\"lake-content\">\n<div class=\"lake-content\">\n<h3 id=\"T1YmP\" class=\"fusion-responsive-typography-calculated\" style=\"--fontsize: 28;

class=\"ne-text\">Aufgrund des gro\u00dfen Unterschieds in der Biegefestigkeit zwischen G.657A2 und G.652D Singlemode-Fasern und weil das Pigtail-Faser-Patchkabel selbst relativ weich ist, l\u00e4sst es sich in der Anwendung sehr leicht mit einem kleinen Radius biegen.<\/span><\/p>\n<p id=\"u7d75e785\" class=\"ne-p\"><span class=\"ne-text\">Nach den statistischen Daten zu Installations- und Wartungsfehlern in einem gro\u00dfst\u00e4dtischen Netz betr\u00e4gt der Anteil der Netzausf\u00e4lle, die auf einen unzureichenden Biegeradius der Glasfaser-Patchkabel zur\u00fcckzuf\u00fchren sind, bis zu 50 %. <\/span><\/p>\n<p id=\"u73e43894\" class=\"ne-p\"><span class=\"ne-text\">Daher ist es ratsam, das Glasfaserkabel mit G.657A2 zu verwenden, um das ankommende optische Kabel w\u00e4hrend der FTTH-Installation zu beenden.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-2 fusion-flex-container
