Down phambili izibopho

Down kuholele izibopho eklanyelwe fixate optical fibre ikhebula ye diameters ezahlukene, ku-pole, imibhoshongo, lapho phansi-ehola umzila noma up-ehola izindlela ezidingekayo. Ngokuvamile le-accessory fibre optic efakwe ne yokudlulisela izintambo ngesikhathi nezipani kusuka ngamamitha 1 kuya 2. Kunezinhlobo ezimbili eziyinhloko yalesi iconsi hardware zasemoyeni:

* Down ngocingo owayephambili izingongolo
* Down ngocingo owayephambili kwemibhoshongo
Zonke lezi izesekeli Specific abazinikezele ukuba fixate ADSS, OPGW, nezinye iconsi round optical fibre amakhebuli. Isiza ukugwema ilele, kunyakaze, ukuzithumela kwezinye izindawo nokufa of ikhebula phakathi ukusetshenziswa sezulu nomoya nemibandela.

Down izibopho phambili zakhiwe ngezinto insimbi engagqwali, aluminium, Thermoplastic. Lokho insures ukumelana ukugqwala okusezingeni eliphezulu futhi ziqinisekise phakathi nenkathi ende yeminyaka ukusetshenziswa.

Jera unikeza zonke emalungeni ikhebula kanye izesekeli, okuyinto edingekayo ekwakheni izindleko yokudlulisela network: kubakaki pole, nisishiye siboshwé ngebhande esigxotsheni, engagqwali band futhi buckles, izingwegwe, turnbuckles, amaketango, Kuvunguza vibration dampers, ikhebula nokunensa isitoreji, parallel inkatho izixhumi.

Zonke yesifunda wadlula ukuhlolwa eqine, operation isipiliyoni okushisa ezisukela -60 ° C kuze kube +60 ° C test, izinga lokushisa ngebhayisikili test, ukuguga test, ukugqwala ukumelana yokuhlola njll
