Khoov Insensitive Fiber-A Zoo Tshaj Taw rau FTTH
Nws paub tias tag nrho cov kab mob fiber ntau yuav muaj ib qho kev tsis muaj zog thaum tso FTTH (Fiber rau hauv tsev): attenuation. Ib qho kev sib tw lossis khoov ntawm kab ntau dhau lawm yuav ua rau qhov kev tsaus ntuj zuj zus tuaj yeem rhuav koj daim ntawv thov nrog cov teeb liab. Yog tias qhov kev puas tsuaj loj heev, tus neeg siv feem ntau yog muag nrog ib qho kev xaiv: dump nws los yog yuav ib lub tshiab. Yuav kom daws tau qhov teeb meem, khoov cov iav khov tsis yog tsim los ua rau qis qis dua qhov muag poob qis dua nyob hauv kev khoov. Nyob rau hauv no txoj kev, cable bending yuav tsis yog ib qho chaw khuam siab rau koj kev siv installation.
Khoov cov hlwv tsis pub muaj peev xwm tsim tau qis qis thaum kis lub teeb tawm txawm tias lawv khoov duav dhau qhov khoov vojvoog. Hauv khoov pob fais fab, ib qho chaw nkaum ntawm qhov muag tau ua nrog qis dua cov ntaub ntawv txheeb xyuas qhov khoom nruab nrab ntawm cov tub ntxhais kom lub teeb ploj tuaj yeem xav txog rov qab rau hauv, yog li nrhiav cov ntaub ntawv tsis tau. Nyob rau tib lub sijhawm, lwm yam xws li cov kabmob ntawm cov kabmob, cov kabmob, cov hom ib yam lossis cov suab hauv multimode, thiab lwm yam yog qhov tseem los ua kom cov kev poob haujlwm tsawg dua vim muaj fiber ntau ntau hauv cov kev teeb tsa thaum siv lub sijhawm losyog kho.
Fiber cable installation tsis yog vim cov hlua khoov ntawm cov ntxhab (hauv cov nplhaib thaj, racks, nkag / tawm cov ntsiab lus, thiab lwm yam) yuav zam tau.
Khoov cov cab khawm cov khwb nyhiab yog qhov tseem ceeb heev rau cov chaw siv hluav taws xob hauv tsev uas lawv siv tau tam sim no los ntawm cov phab ntsa, cov ncej, cov tav, ducts, thiab lwm yam tsis sib txig hauv cov vaj tse.
Cov kev siv ntau dua bandwidth tuaj yeem tso siab siv cov khoov rau cov khoov tsis zoo uas ua rau tsis dhau ntawm cov fibers tsis tuaj yeem ua rau ntau qhov kev kawm degradation.
Khoov cov khib nyiab kuj qhia tau tias qhov teeb meem loj tshaj plaws ntawm qhov chaw fibers tas rau cov chaw siv clamping, khi-wrapping los yog stapling.
Khoov cov nplais hluav taws xob yuav tsum tau spliced nrog tib txoj hauv kev siv rau cov cables li qub, thiab feem ntau, cov khoom siv fiber ntau txuas thiab cov khoom siv yog sib npaug nrog cov khoov rau cov khoov pob.
Nrog kev nruam coob dua ntawm kev siv bandwidth, tooj liab cab ncav cuag lawv txoj kev txwv tsis pub ua txoj haujlwm. FTTH (Fiber rau lub Tsev) yuav tsum tau hloov cov tes hauj lwm tooj liab nrog khoov cov khib nyiab. Cov khoov cov hlua khau tsis muaj tsawg dua kev sib piv nrog cov kab hluav taws xob ciav hlau thiab qhov no yuav ua rau lub installation thiab kev kho ntawm cov fibre fiber ntau ntau.
Nyob hauv FTTH tes hauj lwm, tib neeg yuav tsum muaj cov cab faj siv hluav taws xob kom khov kho kom yooj yim heev kom nws yooj yim dua hauv lub tsev, xws li cov ntsiab lus angled hauv cov chav hauv phab ntsa. Ib qho txiaj ntsig zoo dua peb tuaj yeem tau txais los ntawm khoov cov hlua hluav taws xob yog tias lawv yog chaw txuag tau. Qhov no kuj yog qhov sib txawv ntawm yav tom ntej fiber optic network-me, denser thiab ntau yam ntxiv. Ntau cov tuam txhab xws li FOCC tau muab cov khoov fiber ntau optic cables raws li ITU-T G657 qauv.
Khoov cov hlwv fais fab tsis tuaj yeem ua kom qis zog poob qis dua nyob rau hauv cov neeg mob khoov. Qhov hom kab cable no tseem ceeb heev rau daim ntawv thov FTTH (Fiber rau lub Tsev) kev nkag mus rau qhov network. FOCC khoov khawm cov khauj khab muaj fiber ntau nyob rau hauv multimode (OM2, OM3 thiab OM4) thiab tib lub hom phiaj (OS2) tes hauj lwm. Txhua txoj hlua khau tsis zoo siv hluav taws xob yog tsim nrog cov khoom zoo thiab muaj kev ntsuam xyuas tes kom zoo rau kev kho qhov muag zoo.
