Intambo yokuwisa i-FTTH yangaphandle exhasayo yohlobo lweBow-Type

Intambo ye-optical ye-Aipu-waton GJYXCH kunye ne-GJYXFCH yintambo yokuhla ye-FTTH yangaphandle. Intambo ye-optical iqulethe iifayibha ze-optical ze-silica eziyi-1 ~ 4 ezine-coating, ezinokuba yi-G657A1 okanye i-G652D. Iifayibha ze-optical ezenziwe ngoyilo olufanayo, izinto kunye nenkqubo kufuneka zisetyenziswe kwi-batch efanayo yeemveliso, kwaye iifayibha ze-optical mazibekwe embindini wentambo ye-optical. Umaleko we-coating yefayibha ye-optical unokuba nombala. Umbala womaleko onemibala kufuneka ube luhlaza okwesibhakabhaka, orenji, luhlaza, mdaka, ngwevu, mhlophe, bomvu, mnyama, tyheli, mfusa, pinki okanye i-cyan ngokuhambelana ne-GB 6995.2, kwaye ifayibha enye inokuba ngumbala wendalo. Ulwakhiwo lwe-coating, inqanaba lokujonga amandla efayibha, ububanzi be-mode field kunye neeparameter zobungakanani, ubude be-wavelength obunqunyiweyo kunye nokulahleka kokugoba kwefayibha ye-optical yemode enye esetyenziselwa iintambo kufuneka kuhambelane nemigaqo ekwiTheyibhile 1, 2 kunye ne-3 ngezantsi. Ilungu lamandla kwintambo yokuwisa i-optical linokuba yintambo yentsimbi engagqwaliyo enamandla aphezulu okanye intambo yentsimbi ene-phosphate, okanye ilungu eliqinisayo elingeyonsimbi lentambo ye-polyester aramid okanye enye i-fiber bundle efanelekileyo, eya kuba ne-Young's modulus eyaneleyo kunye noluhlu lwe-elastic strain. Amalungu anamandla entambo ye-optical kufuneka abe yi-2 parallel kwaye alingane kwintambo ye-optical. Intambo yentsimbi ejiyileyo exhonywe ecaleni ithatha umsebenzi wokuzixhasa. Kwintambo ye-optical ene-PVC sheathed, izinto ze-sheath kufuneka zihambelane nemigaqo ye-hr-70 "70 ℃ soft sheath grade soft PVC plastic" kwi-GB/T 8815; Kwintambo ye-optical ene-polyethylene sheathed optical egcina ilangatye, izinto ze-sheath kufuneka zihambelane nemigaqo ye-YD/T 1113; Umphezulu we-sheath kufuneka ube tyaba kwaye uthambe, kwaye akuyi kubakho mifantu ibonakalayo, amaqamza, imingxunya yesanti kunye nezinye iziphene kwicandelo layo. Umbala we-sheath ngokubanzi umnyama, onokuveliswa ngokweminye imibala efunekayo ngabasebenzisi. Intambo ye-optical mayiphawulwe ngokusisigxina kumphezulu we-sheath, nto leyo engazukuchaphazela ukusebenza kwentambo ye-optical, kwaye umgama phakathi kweendawo zokuqala zeempawu ezikufutshane awuyi kuba ngaphezu kwe-500m.
