I-FTTH yangaphandle eZixhasayo ye-Bow-Type drop Cable

Intambo ye-Aipu-waton ye-GJYXCH kunye ne-GJYXFCH yintambo yokulahla ye-FTTH yangaphandle. Ikhebula le-optical liqukethe i-1 ~ 4 i-silica optical fibers ene-coating, enokuthi ibe yi-G657A1 okanye i-G652D. Iifiber ezibonakalayo ezenziwe ngoyilo olufanayo, izinto kunye nenkqubo ziya kusetyenziswa kwibhetshi enye yeemveliso, kwaye iifiber zamehlo ziya kufakwa kumbindi wentambo yokukhanya. I-optical fibre coating layer ingaba nemibala. Umbala woluhlu olunemibala uya kuba luhlaza, i-orenji, eluhlaza, omdaka, ongwevu, omhlophe, obomvu, omnyama, ophuzi, omfusa, opinki okanye o-cyan ngokuhambelana ne-GB 6995.2, kunye ne-fiber enye ingaba ngumbala wendalo. Isakhiwo sokugquma, inqanaba lokuhlola amandla efayibha, imowudi yentsimi yedayamitha kunye neeparitha zobungakanani, ukunqunyulwa kwe-wavelength kunye nokulahleka kokugoba kwe-fiber optical mode enye esetyenziselwa i-cabling iya kuhambelana nezibonelelo kwiTables 1, 2 kunye ne-3 engezantsi. Ilungu lamandla kwintambo yokulahla i-optical drop inokuba yi-high-stainless steel stainless wire okanye i-phosphated steel wire, okanye i-non-metallic yokuqinisa ilungu le-polyester aramid wire okanye enye i-fiber bundle efanelekileyo, eya kuba ne-modulus eyaneleyo ye-Young kunye ne-elastic strain range. Amalungu anamandla entambo ye-optical iya kuba yi-2 paralleled kunye ne-symmetrical kwi-cable optical cable. Ucingo olungqingqwa lwentsimbi olujingayo ecaleni luthatha umsebenzi wokuzixhasa. Kuba PVC sheathed optical cable, imathiriyeli sheath kufuneka ihambelane nezibonelelo hr-70 "70 ℃ ethambileyo esingxotyeni sodidi PVC iplastiki ethambileyo" kwi GB/T 8815; I-polyethylene ene-flame retardant cable ye-optical, i-sheath material kufuneka ihambelane nemimiselo ye-YD / T 1113; Umphezulu we-sheath uya kuba mcaba kwaye ugudileyo, kwaye akuyi kubakho zintanda ezibonakalayo, amaqamza, imingxuma yesanti kunye nezinye iziphene kwicandelo layo. Umbala we-sheath ngokubanzi umnyama, onokuthi uveliswe ngokweminye imibala efunwa ngabasebenzisi. Intambo ye-optical iya kumakishwa ngokusisigxina kwi-sheath surface, engayi kuchaphazela nayiphi na intsebenzo yentambo ye-optical, kwaye umgama phakathi kweendawo zokuqala zeempawu ezikufutshane awuyi kuba mkhulu kune-500m.
