Raws li lub hauv paus ntsiab lus ntawm cov teeb ua hluav taws xob thiab cov txheej txheem tsim tawm, cov khoom siv hluav taws xob tau cais tau muab faib ua ob hom:fused-tapered hom (FBT)thiabplanar waveguide yam (PLC).
PLC Splitter:
Lub PLC Splitter yog kev sib xyaw ua ke waveguide optical zog faib khoom raws li quartz txheej. Nws lub luag haujlwm tseem ceeb yog faib cov teeb liab kho qhov muag los ntawm ib qho kho qhov muag los rau ntau qhov kho qhov muag. Cov cuab yeej yog tsim los ntawm cov twj siv hluav taws xob sib xyaw ua ke txuas nrog cov hlua hluav taws xob hauv ob qho kawg. Cov nti yog cov khoom siv tseem ceeb. Qhov zoo tshaj ntawm cov nti thiab kev faib tawm channel ncaj qha cuam tshuam rau tus nqi ntawm tag nrho cov splitter. Lub nti muaj ib lub tswv yim thiab N tso zis haujlwm ntxiv. yoj pawv. Cov cuab yeej siv hluav taws xob fiber ntau yog nyob rau sab sauv ntawm qhov nti, thiab lub plhaub ntim tau tsim los ua ib qho khoom siv hluav taws xob sib xyaw nrog ib qho kev tawm tswv yim thiab N ntawm cov xov hluav taws xob.
FBT Splitter:
Lub fusion taper thev naus laus zis yog txhawm rau muab ob los sis ntau qhov xov hluav taws xob nrog cov txheej txheej tshem tawm ua ke, thiab tom qab ntawd yaj thiab ncab lawv ntawm lub tshuab taper, thiab saib xyuas qhov kev hloov pauv ntawm qhov sib cais hauv lub sijhawm. Tom qab cov kev faib tawm sib txig sib xyaw ua kom tau raws li qhov xav tau, cov yaj ncab xaus. Khaws ib qho kho qhov muag (qhov seem raug txiav tawm) raws li kev tawm tswv yim kawg, thiab lwm qhov kawg yog qhov tawm ntau kawg.
