Lub hau hluav taws xob splitter yog ib qho tseem ceeb ntawm qhov ntsuas siab tshaj hauv qhov txuas fiber ntau. Nws mas ua lub luag haujlwm ntawm cov teeb pom kev zoo. Nws feem ntau siv los cais tawm cov teeb liab kho qhov muag ntawm lub kho qhov muag kab davhlau ya nyob twg OLT thiab optical network davhlau ya nyob twg ONU ntawm passive optical network.
Tus kho qhov muag cais tau muab cov hluav taws xob sib kis xa mus rau hauv ib qho kho qhov muag tau rau ntau qhov kho qhov muag. Muaj ntau yam kev faib tawm, 1 × 2, 1 × 4, 1 × N, lossis 2 × 4, M × N. Kev tsim qauv dav dav ntawm FTTH yog: OLT (computer chav chaw ua haujlwm) -ODN (passive optical network faib system) -ONU (tus neeg siv sab), qhov twg kho qhov muag tau siv hauv ODN kom paub tias ntau tus neeg siv khoom siv ib PON interface. Hauv cov qauv PON, thaum kev faib cov vaj tse tawg thiab tsis meej, xws li kev faib tawm ntawm villas, qhov deb yog qhov deb, thiab tus neeg siv khoom siv tsawg, qhov nruab nrab ntawm cov teeb pom kev sib cais tuaj yeem ua kom siv tag nrho cov peev txheej los npog thaj tsam ib puag ncig Cov.
