Ifayibha ye-Optical yinto eyimfuneko kwixesha lenethiwekhi yanamhlanje, kodwa ngaba uyayiqonda ngokwenene i-fiber optical? Ziziphi iindlela zokudibanisa ifayibha? Uthini umahluko phakathi kwentambo yokukhanya kunye nefiber optical? Ngaba kunokwenzeka ukuba ifayibha zitshintshe ngokupheleleyo iintambo zobhedu ezivela ngaphandle
Ziziphi iindlela zokudibanisa ifayibha?
1. Uqhagamshelwano olusebenzayo:
Uqhagamshelo olusebenzayo yindlela yokudibanisa isiza kwisiza okanye kwisiza kwintambo yefiber optic usebenzisa izixhobo ezahlukeneyo zonxibelelwano lwefiber optic (iiplagi kunye neesokethi). Le ndlela iguquguqukayo, ilula, ifanelekile, kwaye inokwethenjelwa, kwaye isoloko isetyenziswa kwiintambo zenethiwekhi yekhompyuter kwizakhiwo. Ukuthotywa kwayo okuqhelekileyo yi-1dB / isinxibelelanisi.
2. Uqhagamshelo olungxamisekileyo (okwaziwa ngokuba) ukunyibilika okubandayo:
Uqhagamshelo olungxamisekileyo lusebenzisa iindlela zoomatshini kunye neekhemikhali ukulungisa kunye nokudibanisa iifiber ezimbini zamehlo kunye. Uphawu oluphambili lwale ndlela kukuba uxhulumaniso lukhawuleza kwaye lunokwethenjelwa, kwaye i-attenuation eqhelekileyo yoxhumo ngu-0.1-0.3dB / iphuzu.
Zinokudityaniswa kwizihlanganisi kwaye ziqhagamshelwe kwiisokethi zefiber optic. Umdibaniso udla i-10% ukuya kwi-20% yokukhanya, kodwa yenza kube lula ukuphinda ulungelelanise inkqubo.Nangona kunjalo, indawo yokudibanisa iya kuhlala ingazinzile ixesha elide kwaye i-attenuation iya kwanda kakhulu, ngoko ingasetyenziselwa ungxamiseko kuphela. ixesha elifutshane.
Inokudityaniswa ngoomatshini. Ukwenza oku, beka isiphelo esinye seentsinga ezimbini ezisikwe ngononophelo kwityhubhu kwaye uzibophe kunye. I-fiber inokulungelelaniswa kwi-junction yokwandisa umqondiso. Ukudibanisa oomatshini kufuna malunga nemizuzu emi-5 ukuze abasebenzi abaqeqeshiweyo bagqibezele, kwaye ukulahleka kokukhanya malunga ne-10%.
3. Uqhagamshelo lwefayibha esisigxina (ekwaziwa ngokuba yi-hot melt):
Olu hlobo loxhumo lusebenzisa ukukhutshwa kombane ukuze udibanise kwaye udibanise iindawo zokudibanisa zefiber. Ngokuqhelekileyo isetyenziselwa ukudibanisa umgama omde, uqhagamshelwano olusisigxina okanye olusisigxina. Isici sayo esiphambili kukuba uxhulumaniso loxhumo lusezantsi phakathi kwazo zonke iindlela zokudibanisa, kunye nexabiso eliqhelekileyo le-0.01-0.03dB / iphuzu.
Nangona kunjalo, xa udibanisa, izixhobo ezikhethekileyo (umatshini welding) kunye nemisebenzi yobuchwephesha iyadingeka, kwaye indawo yokudibanisa kufuneka ikhuselwe ngesitya esikhethekileyo. Iintsinga zimbini zinokudityaniswa ukuze zenze unxibelelwano oluluqilima.
Ifiber eyenziwe yindlela yokudibanisa iphantse yafana nefiber enye, kodwa kukho ukuthomalalisa kancinci. Kuzo zontathu iindlela zokudibanisa, kukho ukubonakalisa kwi-junction, kwaye amandla abonakalisiweyo asebenzisana nomqondiso.
Kuyimfuneko ukuqonda ukulahleka kwefiber optical ukuze kusetyenziswe ngcono i-fiber optical. Umsebenzi ophambili we-Fluke's CertiFiber Pro Optical Loss Test tester ye-fiber loss tester kukuvavanya ilahleko kunye nokusilela kunobangela wefiber.
Umvavanyi weFluke's CertiFiber Pro Optical Loss Test ilahleko yefayibha unoku:
1. Uvavanyo oluzenzekelayo lwemizuzwana emithathu — (amaxesha amane ngokukhawuleza kunabavavanyi bemveli) lubandakanya: umlinganiselo welahleko optical kwimicu emibini yobude bamaza amabini, umlinganiselo womgama kunye nokubalwa kohlahlo lwabiwo-mali lokulahleka kwamehlo.
2. Ukubonelela ngokupasa ngokuzenzekelayo / uhlalutyo lokungaphumeleli olusekelwe kwimigangatho yoshishino okanye imida yovavanyo yesiko
3. Chonga iinkqubo zovavanyo ezingachanekanga ezibangela iziphumo “zelahleko embi”
I-4.Onboard (i-USB) yokuhlola ikhamera yekhamera irekhoda umfanekiso we-fiber endface
5. Iiadaptha zemitha yamandla ezitshintshiselanayo ezikhoyo kuzo zonke iintlobo zesinxibelelanisi esiqhelekileyo (SC, ST, LC, kunye neFC) kwindlela echanekileyo yereferensi yokutsiba enye
I-6.I-locator ye-fault yevidiyo eyakhelwe-ngaphakathi yoxilongo olusisiseko kunye nokufumanisa i-polarity
7. Ukukwazi ukulinganisa i-wavelength ephindwe kabini kwifayibha enye ivumela umhloli ukuba asetyenziswe kwizicelo ezifuna ikhonkco enye yefiber.
Akukho zixhobo ezongezelelweyo okanye iinkqubo ezifunekayo ukuthobela i-TIA-526-14-B kunye ne-IEC 61280-4-1 iimfuno ze-ring flux.
Yintoni umahluko phakathi kwentambo ye-optical kunye nefiber optical
Ikhebula le-optical liqulunqwe linani elithile lemicu ye-optical. Undoqo wangaphandle ugqunywe ngeshethi kunye nomaleko okhuselayo wonxibelelwano kunye nomgama omde wokuhanjiswa kolwazi lomthamo omkhulu.
I-Optical fiber sisixhobo sothumelo, kanye njengocingo olucekethekileyo lweplastiki. I-fiber ebonakalayo encinci kakhulu iya kufakwa kwi-sleeve yeplastiki yokuhambisa ulwazi olude. Ke intambo yefiber optic inefiber optical.
Ekugqibeleni, makhe sithethe ngentambo. Intambo yenziwe nge-condutive wire core, i-insulation layer, kunye ne-seal protection layer. Yenziwe ngezinto zetsimbi (ininzi ithusi, i-aluminium) njengomqhubi, kwaye isetyenziselwa ukuhambisa amandla okanye ulwazi. Iingcingo zijijekile. Iintambo zisetyenziswa kakhulu kwiindawo zokuthutha, izitishi, njl. Enyanisweni, iingcingo kunye neentambo azikho imida engqongqo. Ngokuqhelekileyo, sibiza iingcingo ezinobubanzi obuncinci kunye neeseli ezimbalwa njengeingcingo, kunye neentambo ezinobubanzi obukhulu kunye neeseli ezininzi.
Ngaba kunokwenzeka ukuba iintambo zamehlo zitshintshe ngokupheleleyo iintambo zobhedu ezivela ngaphandle?
Kumaziko amaninzi edatha, ifayibha iye yalawula imarike ngenxa yeemfuno eziphezulu ze-bandwidth. Ukongeza, iintambo zefiber optic azikho phantsi kokuphazamiseka kwe-electromagnetic, kwaye iimfuno zazo zokusingqongileyo azikho nzima njengeentambo zobhedu. Ngoko ke, i-fiber optical kulula ukuyifaka.
Nangona kunjalo, kufuneka kuqatshelwe ukuba nangona i-gap yexabiso phakathi kweefayili ze-optical kunye neentambo zobhedu ziye zancincika, ixabiso elipheleleyo leentambo ze-optical liphezulu kuneentambo zobhedu. Ngoko ke, i-fiber isetyenziswa ngokubanzi kwiindawo ezifuna i-bandwidth ephezulu, njengamaziko edatha.
Kwelinye icala, iintambo zobhedu azibizi kangako. I-Optical fiber luhlobo olulodwa lwefiber yeglasi eethe-ethe ngakumbi kuneentambo zobhedu. Ngoko ke, iindleko zokugcinwa kwemihla ngemihla yekhebula lobhedu liphantsi kakhulu kune-fiber optical. Ikwabonelela ngasemva ukuhambelana nezixhobo ezindala ze-Ethernet ze-10 / 100Mbps.
Ke ngoko, iintambo zobhedu zisasetyenziswa ekuhanjisweni kwelizwi kunye nezicelo zenethiwekhi zangaphakathi. Ukongeza, i-cabling ethe tye, Amandla phezu kwe-Ethernet (POE), okanye i-Intanethi yezinto izicelo ziqhuba ukusetyenziswa kweentambo zobhedu. Ke ngoko, iintambo zefiber optic aziyi kuthatha indawo ngokupheleleyo iintambo zobhedu.
Malunga nolwazi oluncinci lwefiber optical, ndiza kutyhala apha kuye wonke umntu namhlanje. Iintambo zeFiber optic kunye neentambo zobhedu zinokubonelela ngeenkonzo zoqhagamshelo lwe-Intanethi kumakhaya nakumashishini. Enyanisweni, izisombululo zefiber optical kunye nobhedu ziya kuhlala kwixesha elizayo elibonakalayo, kwaye isisombululo ngasinye siya kusetyenziswa apho senza ingqiqo.
