Gewoonlijk hebben optische vezels een bepaalde minimum buigstraal. Het verdient echter aanbeveling de minimale buigstraal ongeveer 10 maal kleiner te houden dan de buitendiameter van de optische vezel. Daarom mag de buigradius van een 4 mm glasvezelkabel niet minder dan 40 mm bedragen.<\/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\">Standaard minimale buigstraal<\/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\">De minimale buigstraal van de G.657A2 optische vezel wordt aanbevolen op 7,5 mm.

De minimum buigende straal van G657A2 optische vezel verwijst naar dat de extra vermindering die bij 1550nm\/1625nm wordt gemeten wanneer de vezel optische kabel in een losse draai van 7.5mm straal is niet 0.5dB\/1.0dB zal overschrijden.<\/span><\/p>\n<p id=\"uc32dc09c\" class=\"ne-p\"><span class=\"ne-text\">De minimum buigende straal van G652D optische vezel verwijst naar dat de optische vezel losjes voor 100 draaien met een straal van 30mm wordt gewonden, en de extra die attenuation bij 1625nm wordt gemeten 0.1dB niet overschrijdt.<\/span><\/p>\n<p id=\"u3216fd28\" class=\"ne-p\"><span class=\"ne-text\">Het bijkomende verlies dat door het buigen van optische vezel met buigende straal wordt veroorzaakt die veel groter is dan zijn diameter wordt macrobending verlies genoemd.

class=\"ne-text\">Uit de testresultaten blijkt dat de inkomende optische FTTH-kabel (G.657A2) een grotere buigweerstand heeft dan die van de vezelpigtailkabel (G.652D), vooral bij een kleine buigradius.<\/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; line-height:

verschil in buigweerstand tussen G.657A2 en G.652D single mode vezel, en de pigtail fiber patchkabel zelf is relatief zacht, is het zeer gemakkelijk te buigen met een kleine radius in de toepassing.<\/span><\/p>\n<p id=\"u7d75e785\" class=\"ne-p\"><span class=\"ne-text\">Volgens de statistische gegevens van de installatie- en onderhoudsfouten in een grootstedelijk netwerk, bedraagt de netwerkstoring die wordt veroorzaakt door de onvoldoende buigradius van de vezellasdraad maar liefst 50%. <\/span><\/p>\n<p id=\"u73e43894\" class=\"ne-p\"><span class=\"ne-text\">Daarom is het raadzaam de vezelkabel met G.657A2 te gebruiken om de inkomende optische kabel te be\u00ebindigen tijdens FTTH-installatie.<\/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
