Optical splitters tuaj yeem muab faib ua kem-hom optical splitters, tais-hom optical splitters, khib-mounted optical splitters, phab ntsa-mounted optical splitters, thiab lwm yam raws li cov Scope ntawm daim ntawv thov. Box-type optical splitters feem ntau yog siv rau optical fiber faib thawv, thiab lwm yam .; tray-type optical splitters feem ntau yog siv rau ODF optical fiber faib thav ntawv thiab kho qhov muag cable hloov lub thawv hauv chav tsev computer; khib-mounted optical splitters yog ntsia rau hauv tus qauv racks; phab ntsa-mounted optical splitters tuaj yeem nruab rau ntawm phab ntsa.
Optical splitter tuaj yeem muab faib ua ob hom: fusion tapered optical splitter thiab planar waveguide (PLC) optical splitter raws li kev tsim khoom sib txawv. Ntawm lawv, cov phiaj xwm waveguide optical splitter (PLC) yog siv dav hauv FTTx thiabPON. Lub fusion tapered beam splitter yog tsim los ntawm fusing ob los yog ntau tshaj optical fibers ntawm sab; Planar waveguide beam splitter (PLC) yog cov khoom siv micro-optical tivthaiv uas siv cov thev naus laus zis photolithography los ua ib qho kev kho qhov muag ntawm lub dielectric lossis semiconductor substrate. Paub txog kev ua haujlwm ntawm ceg. Cov txheej txheem sib cais ntawm ob hom optical splitters zoo ib yam. Lawv ob leeg ua tiav cov ceg sib txawv los ntawm kev hloov cov evanescent field coupling ntawm cov fibers (coupling degree, coupling length) thiab hloov lub voj voog fiber ntau.
Tsis tas li ntawd, lub nqaj splitter muab faib ua 1 × 2, 1 × 4, 1 × 8, 1 × 16, 1 × 32, 1 × 64, thiab lwm yam raws li qhov sib txawv ntawm qhov sib cais.
Lus Cim: Ntawm lub rooj tsavxwm semiconductor engraved, lub "Y"-zoo li tus waveguide coupler yog engraved los ntawm photolithography technology, thiab cov "Y" waveguides txuas ua ke los ua ib tug stepwise lub teeb splitting, uas muaj peev xwm paub 1 × 2, 1 × 4, 1 × 8. 1 × 16, 1 × 32, 1 × 64, thiab lwm yam.
Yuav ua li cas xaiv ntawm ntau hom optical splitters saum toj no? Peb tuaj yeem txiav txim siab ua ntej lub sijhawm thov thiab xaiv qhov tsim nyog optical splitter raws li qhov xav tau tiag tiag. Piv txwv li, nyob rau hauv daim ntawv thov uas muaj ob peb ceg thiab insensitive rau lub teeb wavelengths (uas yog, tsuas yog 1 × 2 los yog 1 × 4 yog txaus), xaiv fusion taper hom Optical splitter: Yog hais tias nws yog siv nyob rau hauv FTTH thiab lwm yam kev siv uas yuav tsum tau. ntau lub wavelengths (uas yog, 1 × 4 los yog ntau tshaj), xaiv ib tug planar waveguide (PLC) optical splitter, vim hais tias cov planar waveguide (PLC) optical splitter yog uniform thiab cov channel yog uniform.
Cov ntsiab cai thiab kev npaj ntawm optical splitter.
Qhov sib cais ntawm cov khoom siv feem ntau yog 1: 2, 1: 4, 1: 8, 1: 16, 1: 32, thiab 1: 64. Yog tias tsim nyog, koj tuaj yeem xaiv 2: N optical splitter lossis non-uniform splitting splitter. Thaum teeb tsa lub optical splitter, qhov kev siv ntau tshaj plaws ntawm txhua qhov chaw PON thiab optical splitter ntawm cov cuab yeej yuav tsum raug txiav txim siab. Raws li tus neeg siv kev faib tawm ceev thiab daim ntawv xa tawm, qhov kev pom zoo ntawm optical splitter ua ke thiab tsim txoj haujlwm tsim nyog yuav tsum raug xaiv. Muaj ob lub hauv paus ntsiab lus rau kev siv optical splitters: ib qho yog siv cov thawj-theem splitting kom ntau li ntau tau, thiab lwm yam yog hais tias tus naj npawb ntawm splitting theem tsis tshaj ob. Muaj peb qhov laj thawj rau kev siv qhov sib cais thawj zaug: ua ntej, nws tuaj yeem siv PON ntau tshaj plaws; thib ob, nws yooj yim los kuaj xyuas qhov tsis raug; thib peb, qhov system muaj kev ntseeg siab.
Yuav ua li cas tso lub splitter?
(1) Siv cov txheej txheem sib cais thawj zaug, thaum lub optical splitter nyob rau hauv cov neeg nyob hauv lub network, lub splitter tuaj yeem ntsia tau rau sab hauv tsev lossis sab nraum zoov. Cov chaw teeb tsa hauv tsev muaj xws li chav tsev computer hauv nruab nrab ntawm cov zej zog, qhov tsis muaj zog tam sim no hauv lub tsev, thiab lub thawv thaiv hauv pem teb. Sab saum toj txuas kho qhov muag cables ntawm optical splitter tuaj yeem los ntawm peb txoj hauv kev, uas yog, thawj-theem optical crossover lub thawv, ob-theem optical crossover box lossis optical fiber splitter lub thawv. Txoj kev no tsuas yog tsim nyog rau qhov xwm txheej ntawm cov nplai loj thiab cov neeg siv siab ceev, xws li cov tsev nyob hauv siab.
(2) Yog hais tias qhov thib ob optical splitting txoj kev yog saws, lub optical splitter yuav muab ntsia tau rau hauv lub caj qaum txheej los yog cov neeg siv faib fiber optic cable txheej. Nyob rau hauv lub pob txha caj qaum txheej, lub splitter yuav muab ntsia tau rau hauv lub qhov rais optical hlws ris box, thib ob optical hlws ris lub thawv los yog nyob rau hauv lub optical fiber faib lub thawv. Txoj kev no yog tsim rau cov xwm txheej uas cov neeg siv tau tawg thiab cov neeg siv tshiab optical cable networks.
Yuav siv lub splitter li cas?
Nrog rau kev nce qib loj ntawm fiber ntau rau hauv tsev (FTTH) hauv Suav teb, daim ntawv thov ntawm ntau yam khoom siv kho qhov muag tau tsim sai heev. Raws li cov tseem ceeb tshaj plaws passive optical ntaus ntawv nyob rau hauv kev tsim kho ntawm fiber ntau rau lub tsev (FTTH), optical splitters yog siv los xyuas kom meej kev sib txuas lus sib txuas, uas yog ib qho tseem ceeb cov cuab yeej rau ib txwm kis tau tus mob. Yog li cas optical splitters siv fiber ntau rau hauv tsev (FTTH) cabling?
Tam sim no, thawj thiab theem nrab spectroscopy feem ntau yog siv hauv engineering. Rau thawj-theem optical splitting txoj kev, kev siv ntawm optical splitter feem ntau muab faib ua plaub qhov xwm txheej: ib qho yog muab tso rau hauv lub hauv paus chaw ua hauj lwm hauv computer chav; lwm qhov yog muab tso rau hauv lub cell computer chav; qhov thib peb yog muab tso rau hauv lub cell optical hloov lub thawv; plaub yog ncaj qha tso rau hauv txoj kev hauv tsev. Rau qhov thib ob-theem splitter, kev siv cov splitter feem ntau muab faib ua peb qhov xwm txheej: ib qho yog tias thawj-theem splitter tau muab tso rau hauv chav ua haujlwm hauv nruab nrab, thiab qhov thib ob-theem splitter muab tso rau hauv lub thawv hloov kho qhov muag; qhov thib ob yog tias thawj theem splitter muab tso rau ntawm txoj kev. Nyob rau hauv lub loj-muaj peev xwm optical crossover lub thawv, qhov thib ob optical splitter yog muab tso rau hauv lub zej zog optical crossover lub thawv; qhov thib peb yog thawj optical splitter yog muab tso rau hauv lub tsev kho qhov muag crossover lub thawv, thiab qhov thib ob optical splitter muab tso rau hauv txoj kev hauv tsev.
Piv txwv li: piv txwv tias qhov chaw ua haujlwm kawg yog 4km rau ntawm lub xovtooj, 4.5km mus rau ntawm tes, 5km mus rau cov neeg siv lub tsev, muaj 20 lub tsev hauv lub xovtooj, txhua lub tsev muaj 30 tsev neeg, thiab tag nrho cov xaim xaim kho qhov muag hauv lub tsev. tsev siv drop-in optical cables, raws li qhia hauv qab no Shown.

(1) Nyob rau hauv cov ntaub ntawv ntawm thawj-theem optical splitting, tag nrho cov kev pab them nqi yog saws, thiab txhua lub tsev yog them rau ntawm ib tug splitting ratio ntawm 1:32. Tus naj npawb thiab qhov ntev ntawm cov pob txha kho qhov muag cable thiab cov khoom siv kho qhov muag tau suav nrog (tus naj npawb ntawm cov kab hluav taws xob kho qhov muag yog nyob ntawm cov tub ntxhais tsim khoom tiag tiag Xav txog cov naj npawb ntawm cov neeg siv ze tshaj rau cov neeg siv, tsis muaj kev txheeb cais ntawm cov khoom siv kho qhov muag. cables los ntawm txoj kev hauv tsev fiber ntau faib lub thawv rau cov neeg sivONU, raws li qhia hauv cov lus hauv qab no.
