Ikhebuli ye-Outdoor ye-FTTH Ezisekelayo Yokudonsa Umnsalo

Intambo yokubona ye-Aipu-waton GJYXCH kanye ne-GJYXFCH iyikhebula yokudonsa engaphandle ye-FTTH. Ikhebula le-optical liqukethe i-1 ~ 4 ye-silica optical fibers ene-coating, engaba i-G657A1 noma i-G652D. Imicu yokubona eyenziwe ngomklamo ofanayo, impahla kanye nenqubo izosetshenziswa kuqoqo elifanayo lemikhiqizo, futhi imicu yokubona izobekwa phakathi nendawo yekhebula le-optical. I-optical fiber coating layer ingaba nombala. Umbala wesendlalelo esinemibala uzoba luhlaza okwesibhakabhaka, owolintshi, oluhlaza okotshani, onsundu, ompunga, omhlophe, obomvu, omnyama, ophuzi, onsomi, opinki noma o-cyan ngokuhambisana ne-GB 6995.2, futhi i-fiber eyodwa ingaba umbala wemvelo. Isakhiwo sokumboza, izinga lokuhlola amandla efayibha, ububanzi benkambu yemodi kanye nemingcele yosayizi, ubude begagasi obunqamuliwe kanye nokulahlekelwa okugobayo kwe-fiber optical yemodi eyodwa esetshenziselwa ikhebula kuzohambisana nezinhlinzeko ezikumaThebula 1, 2 kanye no-3 ngezansi. Ilungu lamandla kukhebuli yokudonsa ebonakalayo kungaba intambo yensimbi engenasici enamandla amakhulu noma intambo yensimbi ye-phosphated, noma ilungu eliqinisayo elingeyona insimbi le-polyester aramid wire noma enye inqwaba yefiber efanele, ezoba nemodulus ye-Young eyanele kanye nobubanzi bokunwebeka bokunwebeka. Amalungu amandla ekhebuli yokubona azoba ngu-2 ahambisanayo futhi alingane kukhebula yokubona. Intambo yensimbi ewugqinsi elengayo ohlangothini ithatha umsebenzi wokuzisekela. Ngekhebula elikhanyayo le-PVC elicwebezelayo, okokusebenza kwe-sheath kufanele kuthobelane nezinhlinzeko ze-hr-70 "70 ℃ ipulasitiki ye-PVC ethambile ye-sheath yebanga elithambile" ku-GB/T 8815; Kukhebula le-polyethylene elineshehethi ye-flame retardant, i-sheath material kufanele ihambisane nezinhlinzeko ze-YD/T 1113; Ubuso bomgobolondo buyoba yisicaba futhi bushelelezi, futhi ngeke kube khona imifantu ebonakalayo, amabhamuza, izimbobo zesihlabathi kanye nezinye iziphambeko esigabeni sawo. Umbala we-sheath ngokuvamile umnyama, ongabuye ukhiqizwe ngokuya ngeminye imibala edingwa abasebenzisi. Ikhebula le-optical lizomakwa unomphela endaweni ye-sheath, engeke ithinte noma yikuphi ukusebenza kwekhebula le-optical, futhi ibanga phakathi kwezindawo zokuqala zezimpawu eziseduze ngeke libe likhulu kuno-500m.
