Chii chinonzi FTTx?
FTTx i "Fiber To The x" uye ndiro izwi rekare rekuwana fiber mufiber optic communications. x inomiririra kwainoenda kune fiber line. Zvakadai se x = H (Fiber kuKumba), x = O (Fiber kuHofisi), x = B (Fiber kuChivakwa). FTTx tekinoroji inotangira kubva pakati pemidziyo yehofisi mukamuri yekufonera yedunhu kusvika kune yevashandisi terminal michina, kusanganisira yekuona mutsara terminal (OLT), Optical network unit (ONU), optical network terminal (ONT).
Maererano nenzvimbo yeONUpamagumo emushandisi weiyo optical network unit, kune akawanda marudzi eFTTx, ayo anogona kukamurwa kuita fiber kunechinjabhokisi (FTTCab), fiber kudivi remugwagwa (FTTC), faibha kuchivakwa (FTTB), faibha kuenda kumba (FTTH), faibha Kuhofisi (FTTO) uye mamwe mafomu ebasa. US opareta Verizon inoreva FTTB neFTTH sefiber kunzvimbo (FTTP).
FTCab(Fiber KuCabinet）
Tambo yechinyakare inotsiviwa ne optical fiber. TheONUinoiswa pajunction box. TheONUpazasi inoshandisa waya yemhangura kana imwe midhiya kubatanidza kune mushandisi.
FTTC(Fiber kusvika kuCurb）
Kuiswa uye kushandiswa kwetambo dzemaziso kubva kuhofisi yepakati kuenda kumigwagwa mukati mezviuru zvemamita edzimba kana mahofisi. Kazhinji, chinongedzo chekufambisa chebroadband chiri padyo nemushandisi chinoiswa pekutanga. Pakange pave kudiwa masevhisi ebroadband, iyo fiber inogona kukurumidza kutungamirwa kumushandisi uye iyo fiber inogona kusvika kumba.
FTTB(Fiber kuChivakwa)
Iyo inzira yekuwana Broadband yakavakirwa pane yakagadziridzwa optical fiber network tekinoroji. Inoshandisa fiber kuchivakwa uye netiweki tambo kuenda kumba kuti iwane mushandisi Broadband kuwana. Kazhinji, yakatsaurirwa mutsara yekuwana inoshandiswa, iyo iri nyore kuisa uye inogona kupa yakakwira kumusoro uye yakadzika mwero we10Mbps (yakasarudzika).
FTTH(Fiber Kumba）
TTH inoreva kuiswa kweiyo optical network unit (ONU) pamushandisi wepamba kana mushandisi webhizinesi. Iri imhando ye optical access network application iri padyo nemushandisi kunze kweFTTD (optical fiber to desktop) mune yekuona yekuwana yakatevedzana. Tekinoroji yePON yave hotspot yakagovaniswa nevashandisi vepasi rose uye inoonekwa seimwe yeakanakisa tekinoroji mhinduro kuwana FTTH.
FTTP(Fiber To The Premise）
FTTP izwi rekuNorth America. Inosanganisira FTTB, FTTC, uye FTTH mune nhete pfungwa, uye inotambanudza optical fiber tambo kudzimba kana mabhizinesi.
