Kev Taw Qhia ntawm Fiber Optic Splitter

Cov hluav taws xob fiber ntau splitter, lub npe hu ua fiber ntau txuas, yog tshwj xeeb fiber ntau cov khoom siv nrog ib lossis ntau cov xov nkag ua ke kom faib cov cim kho qhov muag rau ob lossis ntau qhov cov xov hluav taws xob ntawm qhov ntsuas kom pom tseeb. Nws yog ib qho tseem ceeb tshaj dhau los hauv cov kab ke txuas hauv fiber ntau, tshwj xeeb tshaj yog siv rau lub qhov txuas (passive optical network) (EPON, GPON, BPON, FTTx, thiab lwm yam), txhawm rau txuas MDF (Main Distribution Ncej) thiab cov khoom siv davhlau ya nyob twg thiab ua tiav ceg ntawm lub teeb liab muag. Cov ntawv no yuav ua ib qho kev qhia ntawm fiber optic splitter los ntawm nws cov nta thiab hom hom.

Cov hluav taws xob fiber ntau splitter los nyob rau ntau qhov sib txawv thiab ntau thiab tsawg los sib cais los yog sib xyaws sib xyaws nrog qhov poob tsawg. Txhua qhov sib cais yog tsim tawm hauv cov txheej txheem uas yooj yim tshaj plaws uas tsim cov khoom siv txhim khu kev qha, khoom siv qis. Lawv cov fiber ntau qhov ntev thiab / lossis nrog cov ntawv xaus ntawm ib hom yog xaiv tau. Cov kev sib cais feem ntau muaj nyob rau hauv 900µm lub raj xoob thiab 250µm liab qab fiber ntau. 1 × 2 thiab 2 × 2 daim txuas ntxiv tuaj nrog tus qauv nrog lub tes tsho thaiv hlau los npog qhov sib cais. Cov khoom lag luam ntau dua suav nrog lub thawv tiv thaiv cov khoom sib cais.

Cov fiber ntau optic splitter los hauv singlemode thiab multimode fiber ntau hom. Cov pa hluav taws xob sib txuas ntawm cov hluavtaws fiber ntau yog FC lossis SC hom, tab sis ntau cov couplers tseem ua raws li LC, LC / APC, SC, SC / APC, FC, FC / APC, thiab ST. Vim tias qhov ntsaws ntsaws yog qhov khoom siv passive, nws yog qhov tsis haum rau EMI (hluav taws xob cuam tshuam), noj tsis muaj hluav taws xob thiab tsis ntxiv cov suab nrov rau cov qauv tsim. Nws cov qauv siv passive yog ob-kev taw qhia thiab kev ua haujlwm ywj pheej ntawm nthwv dej, tiv thaiv tsuas yog los ntawm cov yam ntxwv lub cev ntawm PMMA (Poly (Methyl Merthiolate)) cov tub ntxhais fiber.

Raws li cov thev naus laus zis siv los ua kev sib cais, muaj ob hom kev sib cais optical: FBT splitter thiab PLC splitter. Txhua yam muaj ob qho zoo thiab qhov tsis zoo thaum xa lawv mus rau hauv qhov kev ntsuas siab ua kom qhov ntsej muag.

FBT splitters fused nrog cov cua kub uas zoo sib xws rau ib-rau-ib qhov fusion splice. Cov fibers muaj raws li hauv cov pab pawg los tsim ib qho chaw thiab ntev. Tshav kub yog siv rau cov kab hluav taws xob sib xyaw thaum cov fibers tau soj ntsuam rau polarization-dependant poob (PDL), sib faib ua kom sib faib thiab ntxig tsis txaus (IL). Thaum cov ntsuas tsis tau dhau los ntawm txhua qhov fibers, txheej txheem fusion nres.

FBT splitters zoo-paub thiab yooj yim rau cov khoom lag luam, yog li txo tus nqi tsim khoom. Lawv tuaj yeem faib cov hluav taws xob tsis sib xws, tsis sib thooj lossis tsis sib txig, raws li qhov xav tau ntawm kev soj ntsuam tiag tiag. Dhau li, FBT splitters tuaj yeem ua haujlwm ntawm peb txoj haujlwm sib txawv, xws li 850 nm, 1310 nm thiab 1550 nm. Vim tias cov txiaj ntsig no, cov cais tawm no tau siv dav rau hauv cov phiaj xwm dhau los, tshwj xeeb tshaj yog piv txwv qhov twg cov teeb tsa sib cais me me (1 × 2, 1 × 4, thiab lwm yam).

Txawm li cas los xij, FBT splitters raug txwv nyob rau hauv cov xov tooj ntawm cov sib cais zoo uas tuaj yeem ua tiav hauv ib qho piv txwv, yog li ob peb yuav tsum tau spliced ua ke thaum sib cais loj yuav tsum tau tsim. Dhau li, nws cov teeb tsa tsis zoo yuav tsis tuaj yeem lav cov teeb meem yam tsis zoo saib zoo nkauj thiab qhov tsis tau ntxig hloov pauv hloov nrog kev hloov pauv kub.
