Kev tsim kho kev lag luam ntawm FTTH Raws li kev siv tshuab, FTTH tau tam sim no tau lees paub thiab cov thev naus laus zis tau loj hlob lawm. Muaj ob txoj kev siv hluav taws xob zoo siv rau FTTH, P2P (taw tes rau qhov nruab nrog thev naus laus zis) thiab P2MP (point-to-multipoint PON).
P2P (Peer-to-peer) yog ib tus phooj ywg-rau-phooj ywg network technology uas tso cai rau ob tus neeg siv yam tsis muaj pej xeem IP sib txuas lus ncaj qha.
PON (Passive Optical Network) yog passive kho qhov muag network, uas yog hais txog ODN (Optical Distribution Network) nruab nrab ntawm OLT (Optical Line Terminal) thiab ONU (Optical Network Unit) tsis muaj cov khoom siv nquag thiab tsuas yog siv cov khoom siv kho qhov muag thiab cov khoom tiv thaiv. Cov. PON mas siv cov kev sib txuas lus sib tshooj sib txuas ua ke thiab yog cov thev naus laus zis tseem ceeb kom paub FTTB / FTTH.
PON thev naus laus zis tuaj yeem muab faib ua txoj kev siv Pellbandband kom tau txais kev pabcuam TDM kev pabcuam me me thiab ATM kis-raws li BPON (APON) rau kev nkag mus rau broadband, EPON thev naus laus zis raws Ethernet pob xa mus, thiab GPON uas coj mus rau hauv kev koom ua ke ntawm ATM / Ethernet / TDM thev naus laus zis Cov. Peb hom no yog tag nrho cov PON thev naus laus zis uas tau paub txog FTTX kev lag luam.
