Lub splitter yog ib feem ntawm kev tsim lub PON network, uas yog ib tug passive ntaus ntawv txuas OLT thiab 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 faib rau txhua qhov 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 qhov tshwj xeeb uplink optical interface rau kev sib kis. Thaum lub teeb liab kho qhov muag raug xa mus los ntawm uplink optical interface mus rau downlink optical interface, lub teeb liab kho qhov muag lub zog / lub zog yuav txo qis, thiab tib yam siv tau thaum nws hloov los ntawm downlink optical interface mus rau uplink optical interface. Lub teeb liab optical siv los ntawm txhua qhov downlink optical interface tuaj yeem yog tib yam lossis txawv
Ua hauj lwm hauv paus ntsiab lus ntawm ib tug splitter: Thaum ua teeb liab teeb liab nyob rau hauv ib hom kev kho qhov muag fiber ntau, lub zog ntawm lub teeb tsis yog tag nrho concentrated nyob rau hauv lub tub ntxhais thiab propagates. Ib qho me me propagates los ntawm cladding ze ntawm lub hauv paus. Yog hais tias lub cores ntawm ob optical fibers nyob ze txaus, lub hom teb ntawm lub teeb kis nyob rau hauv ib tug fibers yuav nkag mus rau lwm yam fibers, thiab lub teeb liab teeb liab yog redistributed ntawm ob fibers.
Splitter poob
1. Lub zog kho qhov muag poob yog cuam tshuam nrog cov ceg kho qhov muag, thiab txhua qhov 1: 2 splitting ua rau poob ntawm 3.5dB;
2. Qhov loj ntawm optical fais fab poob txiav txim qhov kev ncua deb uas yuav kis tau;
3. Bandwidth vs. Nqi: Qhov nruab nrab muaj bandwidth nyob rau hauv ib tsev neeg nyob ntawm qhov loj ntawm qhov optical division ratio, thiab qhov siab dua qhov optical division ratio, tus nqi sib faib ib tsev neeg tsawg dua rau OLT.
Splitter hom
Raws li cov txheej txheem tsim khoom sib txawv, cov khoom sib cais feem ntau muab faib ua ob pawg: FBT hom (fused cone splitter) thiab PLC hom (planar waveguide fais fab splitter).
Melt stretching technology yog txheej txheem ntawm bundling ob los yog ntau tshaj optical fibers ua ke thiab ces melting thiab stretching lawv ntawm ib tug stretching tshuab. Thaum lub sij hawm stretching txheej txheem, tus coupling piv ntawm txhua fiber yog saib xyuas. Tom qab qhov sib piv ua tau raws li qhov yuav tsum tau ua, cov txheej txheem melting thiab stretching xaus. Ib qho kawg khaws ib qho fiber ntau (tus so raug txiav tawm) raws li qhov kev tawm tswv yim kawg, thiab lwm qhov kawg ua haujlwm raws li cov khoom tso tawm ntau qhov kawg.
Planar optical waveguide technology yog raws li kev siv tshuab kho qhov muag, siv cov tshuab semiconductor los tsim cov khoom siv kho qhov muag waveguide branching, thiab kev ua haujlwm branching tiav ntawm lub nti.
Txheej txheem txheej txheem ntawm PLC hom spectrophotometer:
Raws li daim ntawv thov, nws tuaj yeem muab faib ua: thawv hom splitter, tais hom splitter, khib hom splitter, phab ntsa mounted splitter, thiab lwm yam.
Box hom splitters yog siv nyob rau hauv ODF racks nyob rau hauv lub computer chav, optical cable hlws ris thawv, thiab lwm yam
