Optical fibre cables - Part 5-20: Family specification - Outdoor microduct fibre units, microducts and protected microducts for installation by blowing
IEC 60794-5-20:2014(E) is a family specification that covers outdoor microduct fibre units and corresponding microducts and protected microducts for installation by blowing. The protected microducts are intended for duct, directly buried or lashed applications. Microduct fibre units differ from microduct optical fibre cables (see IEC 60794-5-10) in that they provide less protection to the fibres that they contain. Specifically, microduct fibre units rely on the structure of the microduct, protected microduct or appropriate housing to support installation and to provide additional mechanical protection for the optical fibre over the lifetime of the product. Systems built with components covered by this standard are subject to the requirements of sectional specification IEC 60794-5 where applicable. Keywords: outdoor microduct fibre units, installation by blowing
Lichtwellenleiterkabel - Teil 5-20: Familienspezifikation für Mikrorohr-LWL-Einheiten, Mikrorohre und geschützte Mikrorohre zur Installation durch Einblasen für die Anwendung im Freien
Câbles à fibres optiques - Partie 5-20 : Spécification de famille - Eléments fibres en microconduit extérieur, microconduits et microconduits protégés pour installation par soufflage
IEC 60794-5-20:2014 est une spécification de famille qui couvre les éléments fibres en microconduit extérieur, ainsi que les microconduits et microconduits protégés correspondants pour installation par soufflage. Les microconduits protégés sont destinés à des applications de conduits, d'enfouissement direct ou de câbles lacés. Les éléments fibres en microconduit se différencient des câbles à fibres optiques en microconduit (voir l'IEC 60794-5-10) par une protection moindre des fibres contenues. De manière spécifique, les éléments fibres en microconduit reposent sur la structure du microconduit, du microconduit protégé ou du logement approprié pour supporter leur installation et pour fournir une protection mécanique supplémentaire à la fibre optique pendant la durée de vie du produit. Les systèmes intégrant des éléments couverts par la présente norme sont soumis aux exigences de la spécification intermédiaire IEC 60794-5, le cas échéant.
Optični kabli - 5-20. del: Skupinska specifikacija za mikrokanale za zunanjo uporabo za optične enote, mikrokanale in zaščitene mikrokanale za vgradnjo z vpihovanjem (IEC 60794-5-20:2014)
Standard EN IEC 60794-5-20 je skupinska specifikacija, ki zajema mikrokanale za zunanjo uporabo za optične enote, ustrezne mikrokanale in zaščitene mikrokanale za vgradnjo z vpihovanjem. Zaščiteni mikrokanali so namenjeni vgradnji v kanale, podzemeljske ali povezane naprave. Mikrokanali za optične enote se razlikujejo od mikrokanalov optičnih kablov (glejte IEC 60794-5-10) v tem, da vlaknom, ki jih vsebujejo, zagotavljajo manj zaščite. Predvsem so mikrokanali pri zagotavljanju dodatne mehanske zaščite optičnim vlaknom med življenjsko dobo izdelka odvisni od sestave mikrokanala, zaščitenega mikrokanala ali ustreznega ohišja, ki podpira namestitev. Za sisteme, zgrajene s komponentami, ki so zajete v tem standardu, veljajo zahteve področne specifikacije IEC 60794-5, kjer je to primerno. Dodatek A navaja primere mikrokanalov za optične enote za uporabo na prostem in mikrokanalov. Dodatek B opisuje okvirno podrobno specifikacijo za mikrokanale za optične enote za uporabo na prostem in povezane mikrokanale ter podaja nekatere minimalne zahteve. Podrobna specifikacija izdelka se lahko pripravi na osnovi te skupinske specifikacije z uporabo dodatka B kot vodnika. Dodatek C podaja normativne konstrukcije izdelka za mikrokanale za optične enote, mikrokanale in zaščitene mikrokanale. Na parametre, navedene v tem standardu, lahko vpliva merilna negotovost, ki se pojavi zaradi merilnih napak ali napak umerjanja zaradi pomanjkanja ustreznih standardov. Kriterije sprejemljivosti naj bi obravnavali ob upoštevanju teh pomislekov. Število preskušenih vlaken mora biti reprezentativno za načrtovanje mikrokanalov za optične enote, o čemer naj bi se dogovorila stranka in dobavitelj.
