Inethiwekhi ye-PON iqukethe izingxenye ezintathu: I-OLT (imvamisa ibekwe egumbini lekhompyutha), i-ODN, ne-ONU (imvamisa ibekwe ekhaya lomsebenzisi noma ephaseji eliseduze nomsebenzisi). Phakathi kwazo, ingxenye yemigqa nemishini esuka ku-OLT iye ku-ONU ayisebenzi, ngakho ibizwa ngokuthi i-Passive ...

1, Ngaphambi kokwethula i-FTTR, ake siqonde kafushane ukuthi iyini i-FTTx. I-FTTx isifinyezo se-"Fiber To The x", sibhekisela ku-"fiber kuya ku-x", lapho u-x engameleli kuphela indawo lapho i-fiber ifika khona, kodwa futhi ihlanganisa okokusebenza kwenethiwekhi yokubona efakwe kuth...

Iyini i-fiber optic transceiver? Ama-transceivers e-Fiber optic angamayunithi wokuguqula imidiya ye-Ethernet ashintshanisa amasiginali kagesi aphekiwe asontekile amabanga amade namasignali okubona amabanga amade, aziwa nangokuthi iziguquli zefayibha ezindaweni eziningi. Umkhiqizo uyi-gen...

Ukuthuthukiswa kobuchwepheshe be-Power over Ethernet (POE) kunamandla kakhulu. Ukuthuthukiswa kwalobu buchwepheshe kungenza kube lula ukufakwa nokuthunyelwa kwemishini kagesi, ngaleyo ndlela kuqede isidingo sezintambo ezizimele zokudlulisela. Namuhla, ubuchwepheshe bokuhlinzeka ngogesi...

Kungakhathaliseki ukuthi iyiphi indlela esetshenziswayo ukuze kuzuzwe ukuxhumana kwembobo yenethiwekhi, ayikwazi ukuhlukaniswa nezimiso ezijwayelekile ezifanele. Kodwa-ke, i-Ethernet ebandakanyeka ochungechungeni lomkhiqizo wenkampani yethu i-ONU ilandela ikakhulukazi indinganiso ye-IEEE 802.3. Ngezansi isingeniso esifushane se...

I-TVS - Ifushane Ye-Transient Voltage Suppressor Diode. I-TV iyithuluzi lokuvikela i-voltage elikhawulela ugesi omningi ngendlela ye-diode. Lapho izigxobo ezimbili ze-TVS zibhekene nokushaqeka kwamandla aphezulu okubuyela emuva, kungaguqula ukuvimba okuphezulu phakathi kwezigxobo ezimbili ...
