Ifiber ye-Optical yifiber eyenziwe ngeglasi okanye iplastiki, kwaye ifayibha ngokwayo ibuthathaka kakhulu kwaye iphuka lula. Kwaye ukufaka i-fiber encinci kwibhatyi yeplastiki ivumela ukuba igobe ngaphandle kokuphuka. Intambo ene-fiber optical ehlanganiswe kwijacket yokukhusela yintambo ye-optical cable. Ngaba intambo yokukhanya inokugotywa ngokuthanda?
Kuba ifayibha inovakalelo kuxinzelelo, ukugoba kunokubangela ukuba isiginali ye-optical ivuze kwifiber cladding, kwaye njengoko igophe lisiya liqina, isibonakaliso sokukhanya siya kuvuza ngakumbi. Ukugoba kunokubangela ii-microcracks ezinokonakalisa ngokusisigxina ifayibha. Ukongeza kwingxaki, amanqaku e-microflex anzima ukufumana kwaye afuna izixhobo zokuvavanya ezibizayo, ubuncinane iibhulorho kufuneka zicocwe okanye zitshintshwe. Ukugoba ifayibha kunokubangela ukuthomalalisa ifayibha. Umthamo wokuthomalalisa ngenxa yokugoba kwefayibha uyenyuka njengoko iradiyasi yokugoba iyancipha. Ukuthotywa ngenxa yokugoba kukhulu kwi-1550 nm kune-1310 nm, kwaye kukhulu ngakumbi kwi-1625 nm. Ngoko ke, xa ufaka i-fiber jumpers, ngakumbi kwindawo ephezulu yoxinaniso lwe-cabling, i-jumper ayifanele igobe ngaphaya kwe-radius yokugoba eyamkelekileyo. Ke yeyiphi iradiyasi efanelekileyo yokugoba?
I-fiber bend radius yi-engile apho i-fiber inokugoba ngokukhuselekileyo nakweyiphi na indawo. Imitha yokugoba iFayibha yahlukile kuzo zonke iintambo okanye iintambo zokubopha kwaye zinokwahluka ngokuxhomekeke kuhlobo lwentambo okanye indlela eyenziwe ngayo. Ubuncinci berediyasi yokugoba ixhomekeke kububanzi kunye nohlobo lwentambo yokukhanya, ngokuqhelekileyo ifomyula isetyenziswa: iradiyasi egobayo ephantsi = i-diameter yangaphandle yekhebula le-optical x i-multiple of the optical cable.
Umgangatho omtsha we-ANSI/TIA/EIA-568B.3 uchaza ubuncinci bemigangatho yeradiyasi egobileyo kunye nemikhosi ephezulu yokuqina kwe-50/125 micron kunye ne-62.5/125 micron fiber optic cables. Ubuncinci berediyasi yokugoba iya kuxhomekeka kwintambo ethile yefiber optic. Kwimeko yokungabikho koxinzelelo, iradiyasi yokugoba yentambo yokukhanya kufuneka ngokuqhelekileyo ingabi ngaphantsi kweshumi le-diameter yangaphandle (OD) yentambo yokukhanya. Ngaphantsi kokulayishwa kwe-tensile, i-radius egobayo yentambo ye-optical yi-diameter yangaphandle yekhebula le-optical 15 amaxesha. Imigangatho yoshishino yeentambo eziziintambo zemowudi enye ngokuqhelekileyo ichaza iradiyasi egobileyo ephindwe kalishumi kunodayamitha engaphandle yentambo enebhatyi okanye i-intshi ezi-1.5 (38 mm), nokuba yeyiphi enkulu. I-fiber ye-G652 esetyenziswa ngokuqhelekileyo inomlinganiselo omncinci wokugoba we-30mm.
I-G657, esetyenziswe kwiminyaka yamuva, inomlinganiselo omncinci we-bend, kuquka i-G657A1, i-G657A2 kunye ne-G657B3 Ubuncinci be-bend radius ye-G657A1 yi-10mm, i-G657A2 i-fiber yi-7.5mm, kunye ne-fiber G657B3 yi-5mm. Olu hlobo lwefayibha lusekwe kwifayibha ye-G652D, ephucula iimpawu zokuthomalalisa ukugoba kunye neempawu zejometri zefiber, ngaloo ndlela ziphucula iimpawu zoqhagamshelo lwefayibha, ekwabizwa ngokuba yi-goba attenuation fiber insensitive. Isetyenziswa kakhulu kwiFTTx, FTTH, ilungele ukusetyenziswa kwiindawo ezincinci zangaphakathi okanye iikona.
Zombini i-fiber breaks kunye nokunyuka kwe-attenuation kunokuba nempembelelo enkulu ekuthembekeni kwexesha elide lomnatha, iindleko zokusebenza zenethiwekhi, kunye nokukwazi ukugcina nokukhulisa isiseko sabathengi. Ke ngoko, kufuneka sazi ngokucacileyo iradiyasi encinci yokugoba yefayibha ukugcina intambo okanye intambo yokubopha ikwimeko elungileyo yokusebenza.
