Lub splitter yog ib feem ntawm PON network thiab yog ib qho khoom siv passive uas txuas OLT rau ONU. Nws txoj haujlwm yog faib cov ntaub ntawv downlink thiab mloog cov ntaub ntawv uplink. Lub splitter muaj ib tug uplink optical interface thiab ob peb downlink optical interfaces. Cov teeb liab kho qhov muag los ntawm uplink optical interface yog muab faib rau tag nrho cov downlink optical interfaces rau kev sib kis, thiab cov teeb liab kho qhov muag los ntawm downlink optical interface yog sib sau ua ke rau tib lub uplink optical interface rau kev sib kis. Tsuas yog thaum lub teeb liab kho qhov muag raug xa mus los ntawm uplink optical interface mus rau downlink optical interface, optical teeb liab lub zog / kho qhov muag lub zog yuav txo qis, thiab tib yam siv thaum hloov los ntawm downlink optical interface mus rau uplink optical interface. Lub zog ntawm cov teeb liab kho qhov muag tuaj yeem yog tib yam lossis txawv ntawm ib qho downlink optical interface mus rau lwm qhov.
Splitter txoj cai ntawm kev ua haujlwm
Nyob rau hauv ib hom kev kho qhov muag fibers ua optical signals, lub teeb lub zog tsis yog tag nrho cov concentrated nyob rau hauv cov tub ntxhais mus rau propagate, ib tug me me npaum li cas yog propagated los ntawm lub cladding nyob ze ntawm lub tub ntxhais, nyob rau hauv ob fibers nrog lub cores ze txaus, hom teb ntawm lub Lub teeb kis tau los ntawm ib qho fiber ntau tuaj yeem nkag mus rau lwm qhov fiber ntau thiab cov teeb liab kho qhov muag tau muab faib rau hauv ob fibers.
Splitter hom
Splitters tau muab faib ua ob pawg loj raws li cov txheej txheem tsim khoom: FBT (fused cone beam splitter) thiab PLC (planar waveguide power splitter).
FBT thev naus laus zis yog txhawm rau txhawm rau ob lossis ntau dua fibers ua ke thiab tom qab ntawd yaj thiab ncab lawv ntawm lub tshuab rub lub taper, saib xyuas qhov sib txuas sib cais ntawm txhua qhov fiber ntau thaum lub sij hawm ncab, xaus lub yaj thiab ncab tom qab qhov sib faib sib faib mus txog qhov yuav tsum tau muaj, ib kawg. ntawm fiber ntau yog khaws cia (tus so raug txiav tawm) raws li cov tswv yim thiab lwm qhov kawg yog siv los ua ntau qhov tso zis. Cov txheej txheem yaj ncab feem ntau yog siv thaum qhov sib cais tsis sib npaug.
Planar optical waveguide technology yog raws li kev siv tshuab optically, siv cov txheej txheem semiconductor los tsim cov khoom siv kho qhov muag waveguide branching, kev ua haujlwm ntawm kev sib cais yog ua tiav ntawm lub nti. PLC thev naus laus zis tsim qhov sib npaug sib npaug.
PLC hom beamsplitter txheej txheem txheej txheem
Raws li daim ntawv thov ntau yam tuaj yeem muab faib ua: lub thawv hom, tais hom, khib hom, phab ntsa mounted, thiab lwm yam.
Lub thawv hom splitter feem ntau yog siv hauv ODF khib hauv chav neeg rau zaub mov, cable hloov lub thawv, thiab lwm yam.
ShenzhenHTFutureCo., Ltd. tuaj yeem muab PLC splitter raws li koj xav tau, ob qho tib si FBT thiab PLC hom.
Txhawb 1x2, 1x4, 1x8, 1x12, 1x16, 1x32, 2x16, 2x32, thiab lwm yam
