Lub splitter{11}}raws li configuration yog ib yam nyob rau hauv FTTH tes hauj lwm; qhov ncaj qha- kev txiav tawm kev teeb tsa yog ib txwm nyob hauv tsev kawm ntawv lossis chaw lag luam Ethernet- dhau- cov pob txha fiber ntau.
Q: Vim li cas 144-core fiber ntau lub thawv qee zaum txhais tau tias 144 splices thiab qee zaum 144 chaw nres nkoj?
A: Vim tias "144-core" piav qhia txog fiber ntau suav, tsis yog qhov ua haujlwm. Nyob rau hauv 144-core dome splice kaw, tag nrho 144 fibers yog spliced nyob rau hauv lub enclosure thiab tsis muaj chaw nres nkoj tau nthuav tawm sab nraud. Hauv 144-chaw nres nkoj ODF (optical faib thav duab), 144 qhov chaw nres nkoj adapter tau nthuav tawm ntawm lub vaj huam sib luag pem hauv ntej thiab 144 qhov sib txuam pigtails yog spliced hauv. Cov khoom lag luam (kaw vs ODF) qhia koj txoj haujlwm; cov suav fiber ntau qhia koj lub peev xwm. Nco ntsoov lees paub ob qho tib si ua ntej xaj.
Q: Dab tsi yog qhov tsawg kawg nkaus khoov vojvoog hauv lub thawv fiber ntau, thiab vim li cas nws tseem ceeb?
A: Rau tus qauv ib zaug - hom fiber ntau (G.652.D), lub dynamic khoov vojvoog - lub vojvoog thaum lub sij hawm installation thiab routing - yog 30 hli. Lub vojvoog khoov zoo li qub - lub vojvoog nyob rau hauv uas fiber ntau tuaj yeem tawm mus tas li - kuj yog 30 hli rau tus qauv SMF raws li G.657.A1 specifications. Tshiab khoov-insensitive fiber ntau (G.657.A2 lossis B2) muaj qhov nkhaus zoo li qub ntawm 7.5-15 hli. Routing fiber nyob rau hauv nws qhov tsawg kawg nkaus khoov vojvoog ua rau micro-bending, uas ua rau kom attenuation. Nyob rau hauv ib lub thawv compact fiber, nruj pigtail routing nyob ib ncig ntawm cov ces kaum yog feem ntau qhov chaw ntawm micro- dabtsi yog khoov poob nyob rau hauv lub ntsia nroj tsuag.
Q: Kuv puas tuaj yeem ntxiv splice tais rau kuv lub thawv fiber ntau uas twb muaj lawm los ua kom muaj peev xwm?
A: Feem ntau yog, yog tias lub chassis tau tsim los txais cov tais ntxiv thiab lub thawv tsis tau raug thauj mus rau qhov siab tshaj plaws suav. Ua ntej yuav ib lub thawv fiber ntau, nug tus neeg muag khoom seb muaj pes tsawg lub tais qhov chassis muaj nyob rau hauv tag nrho cov piv txwv muaj pes tsawg lub tais nrog rau cov khoom xa tuaj. Ib lub thawv uas xa nrog ob 24- cov tais fiber ntau tab sis muaj plaub lub tais tuaj yeem hloov kho mus rau 96 splice txoj haujlwm hauv thaj teb yam tsis tau yuav ib lub thawv tshiab - qhov tseem ceeb rau kev txiav txim siab rau theem FTTH rollouts.
Q: Hom connector twg muab qhov chaw nres nkoj siab tshaj plaws hauv lub thawv fiber ntau?
A: LC connectors muaj 1.25 hli ferrule thiab daim ntawv me dua li SC (2.5 hli ferrule), yog li ib tug LC duplex adapter occupies roughly ib nrab ntawm lub vaj huam sib luag qhov chaw ntawm SC simplex adapter. Hauv siab - daim ntawv thov ceev - khib-mount ODFs, cov ntaub ntawv chaw thaj chaw thaj chaw - LC tso cai kwv yees li ob npaug ntawm qhov chaw nres nkoj suav ntawm tib lub ntsej muag phaj thaj tsam piv rau SC. Rau cov neeg siv khoom-faus FTTH lub thawv txiav tawm, SC/APC tseem yog hom sib txuas tseem ceeb thoob ntiaj teb vim nws tus nqi qis dua thiab qhov ntau ntawm SC-pigtailed ONTs.
