PLC splitter yog ib qho khoom siv kho qhov muag tsis pom kev uas tuaj yeem faib cov tswv yim kho qhov muag rau hauv ntau qhov tso zis hluav taws xob kho qhov muag, thiab tau siv dav hauv kev siv hluav taws xob tsis zoo. Raws li kev ua haujlwm sib txawv, PLC splitters tau muab faib ua PLC optical splitters (planar waveguide optical splitters) thiab FBT couplers (fused taper optical splitters). Kab lus no yuav ua rau koj xav paub meej txog qhov sib txawv ntawm lawv.
Ua ntej tshaj plaws, ua ntej nkag siab qhov txawv ntawm PLC splitter thiab FBT coupler, cia peb nkag siab luv luv ntawm ob lub optical splitters.
PLC splitter yog tsim los ntawm cov tshuab semiconductor thiab tuaj yeem muab cov kev daws teeb meem zoo rau cov ntawv thov sib cais loj dua. PLC splitters yog tsim los ntawm photolithography ntawm lub quartz iav substrate nrog waveguides uas muaj peev xwm taug kev ib feem pua (sib npaug) ntawm lub teeb. Feem ntau, qhov sib faib kho qhov muag ntawm PLC splitter yog 1x2 ~ 1x128 / 2x128 ~ 2x128 / 1x3 / 1x5 / 1x6 / 1x9 / 1x12, thiab lwm yam, nrog Bare fiber PLC Splitter (250um), Mini Hom PLC Splitter (900um), ABS Hom PLC Splitter, PLC Splitter nrog cov khoom siv kiv cua tawm, LGX Hom PLC Splitter, 1U Vaj Huam Sib Luag PLC Splitter, ODF Hom PLC Splitter thiab lwm yam pob.
FBT coupler txais cov cuab yeej siv hluav taws xob siv hluav taws xob, uas muab ob lossis ntau lub fibers ua ke thiab paub txog kev yaj thiab kos los ntawm lub khob-rub lub tshuab. Txij li thaum lub spliced optical fiber yog qhov tsis yooj yim, lub iav raj ua los ntawm epoxy resin thiab silica feem ntau yog them rau sab nraum lub spliced optical fiber. Nyob rau tib lub sijhawm, ib txheej ntawm stainless hlau raj yog npog sab nraum lub iav raj, thiab thaum kawg kaw nrog silicon. Nrog rau kev loj hlob ntawm cov cuab yeej technology, tus nqi-zoo ntawm FBT coupler tau nce siab thiab siab dua.
Kev ua haujlwm wavelength ntawm PLC splitter yog 1260nm ~ 1650nm, thiab lub wavelength tuaj yeem hloov kho kom txhawb ntau qhov chaw thov; thaum FBT optical splitter coupler tsuas yog txhawb peb lub wavelengths ntawm 850nm / 1310nm / 1550nm thiab tsis tuaj yeem ua haujlwm ntawm lwm qhov wavelengths.
Lub splitting ratio yog hais txog qhov piv ntawm qhov input optical teeb liab mus rau qhov tso zis optical teeb liab ntawm lub optical splitter. Qhov sib piv ntawm PLC optical splitter yog siab li 1: 64, thaum lub splitting ratio ntawm FBT optical splitter yog 1: 32. Hais txog kev hais lus, PLC optical splitter tuaj yeem muab kev ntseeg siab dua. Tab sis qhov sib faib kho qhov muag ntawm FBT optical splitter yog qhov sib txawv thiab txhawb kev hloov kho, xws li 1: 3 / 1: 5 / 1x6 / 1: 9 / 1: 12, thaum PLC optical splitter tsuas tuaj yeem xaiv 1xn / 2xN tus qauv khoom.
PLC optical splitter tuaj yeem ua tiav qhov sib npaug sib npaug sib npaug, thaum FBT optical splitter yog tsim los ntawm ntau qhov sib txuas 1x2. Nws tsis muaj kev tswj cov teeb liab thiab tsis tuaj yeem ua tiav kev sib cais. Tsis tas li ntawd, qhov loj dua qhov sib cais, qhov sib txawv ntawm qhov tsis zoo, uas cuam tshuam rau kev sib kis.
Tam sim no, cov txheej txheem kev kos duab paub tab tsuas tuaj yeem rub tsawg dua 1x4 ib zaug. Yog li ntawd, thaum qhov kev sib cais yog ntau dua 1: 8, FBT coupler xav tau ntau tshaj 7 1x2 cov pob khoom sib txuas, uas yog qhov ua rau yuam kev thiab ua tsis tiav. Qhov ntawd yog hais tias, qhov ntau dua qhov sib cais ntawm FBT coupler, qhov ntau dua qhov ua tsis tiav. Tus nqi tsis ua hauj lwm ntawm PLC optical splitter yog tsawg dua li ntawm FBT coupler, raws li qhia hauv daim duab hauv qab no.
Qhov kub thiab txias yog ib qho tseem ceeb cuam tshuam rau qhov poob ntawm cov khoom siv kho qhov muag, yog li ntawd, kev ruaj ntseg ntawm qhov kub thiab txias plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub cuab yeej. PLC splitter tuaj yeem ua haujlwm ruaj khov ntawm -40 ~ 85 degree , thaum lub sijhawm ua haujlwm kub ntawm FBT coupler yog -5 ~ 75 degree . Raws li kev hais lus, PLC splitter muaj qhov dav ua haujlwm kub ntau. Nws kuj tswj tau qhov kev ua tau zoo hauv ib puag ncig.
PLC optical splitter muaj cov txheej txheem tsim khoom thiab cov nqi siab; thaum FBT txuas yog ua los ntawm cov hlau, cua sov shrinkable raj thiab lwm yam ntaub ntawv. Vim yog cov khoom siv qis thiab cov cuab yeej tsim khoom siv yooj yim, kuj hais lus, FBT coupler yog pheej yig dua.
Hauv luv luv, PLC splitter thiab FBT coupler muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, raws li cov lus qhia hauv qab no:
| Yam khoom | PLC Splitter | FBT Coupler |
| Qhov zoo |

Feem ntau, PLC splitter thiab FBT coupler muaj ntau qhov sib txawv ntawm cov txheej txheem tsim khoom, kev ua haujlwm wavelength, kub, thiab lwm yam tshwj tsis yog rau qhov zoo sib xws thiab qhov loj me. Los ntawm qhov tshwm sim ntawm PLC splitter, nws tuaj yeem pom tau tias kev tsim tshuab ntawm optical splitter tau ua tiav zoo hauv xyoo tas los no. Piv nrog rau cov tsoos FBT coupler, PLC splitter yog ib qho chaw passive nrog kev ua tau zoo dua. Optical Cheebtsam, yog tias koj lub network muaj kev ua haujlwm siab, nws raug nquahu kom koj xaiv PLC splitter es tsis txhob FBT optical splitter coupler.
