Optical splitters ua si lub luag haujlwm tseem ceeb hauv FTTH PON tes hauj lwm qhov twg cov tswv yim kho qhov muag tau faib rau ntau qhov kev tsim tawm, yog li tso cai rau ib tus PON nkaus xwb sib koom nrog ntau tus neeg siv. Cov cuab yeej hluav taws xob tawg tsis muaj cov khoom siv hluav taws xob thiab tsis tas yuav muaj lub zog los ua haujlwm. Lawv feem ntau nruab rau hauv txhua qhov khoos phis tawm ntawm PON OLT (kho qhov muag kab davhlau ya nyob twg) thiab ONTs (optical network terminals) uas OLT pabcuam. Feem ntau, ob yam ntawm cov hluav taws xob fiber ntau tawg tau nrov, uas yog FBT splitters thiab PLC splitters.

Kev siv cov khoom siv hluav taws xob sib cais hauv PON tso cai rau cov neeg muab kev pabcuam kom tshwj xeeb cov leeg nyob hauv caj qaum, qhov tseem ceeb yog siv ib qho fiber ntau los pub noj kom ntau li 64 cov neeg siv tag. Feem sib txig sib piv hauv daim ntawv thov PON yog 1:32, lub ntsiab lus ib qho cov kab hluav taws xob tau faib ua 32 qhov tsim tawm. Thiab cov paib hluav taws xob optic muaj peev xwm kis tau ntau dua 20 km. Yog tias qhov kev ncua deb ntawm OLT thiab ONT yog tsawg (hauv 5 km), koj tuaj yeem xav txog 1:64. Nrog kev sib faib siab dua, PON network muaj ob qho zoo thiab qhov tsis zoo. Fiber optic splitters nrog sib cais sib faib ntau dua tuaj yeem qhia OLT optics thiab cov nqi hluav taws xob raws li tus nqi sib faib khoom noj muaj fiber ntau thiab cov nqi tsim tshiab ntxiv. Tsis tas li ntawd, kev sib cais loj dua tso cai ntau dua thiab cov tswj fiber ntau thaum kawg lub taub hau tau yooj yim dua. Tib lub sijhawm, ntau dua qhov sib cais sib cais sib cais txo bandwidth ib ONU (optical network unit). Thiab yuav muaj nce nqi kho qhov muag qhov nqi ntawm OLT lossis ONU lossis ob qho tib si kom ua tiav cov peev nyiaj siv hluav taws xob loj.
