Okokuqala, sidinga ukuqonda imingcele ehlukahlukene yamamojula optical, okuyizinhlobo ezintathu eziyinhloko (i-wavelength emaphakathi, ibanga lokudlulisela, izinga lokudlulisela), futhi umehluko omkhulu phakathi kwamamojula optical nawo abonakala kulawa maphuzu. 1.Ubude begagasi obumaphakathi Iyunithi ye-t...

I-broadband esiyifaka manje ngokuyisisekelo isekelwe ekudlulisweni kwe-fiber optical. Lapho ufaka i-broadband, sizodinga imodemu yokubona. Uma kuqhathaniswa namarutha ajwayelekile, yimuphi umehluko phakathi kwawo? Nasi isingeniso samamodemu optical. Umehluko ngama-routers. 1. Isimiso ...

Incazelo yokukhanya yenkomba ye-optical fiber transceiver: 1. Isibani senkomba ye-LAN: Izibani zamajekhi e-LAN1, 2, 3, 4 amele izibani ezibonisa isimo sokuxhuma kwe-intranet yenethiwekhi, ngokuvamile ekhanyisa noma ehlala isikhathi eside. Uma ingavuliwe, kusho ukuthi inethiwekhi ayixhunyiwe ngempumelelo ...

Njengamanje, kunabakhiqizi abaningi bangaphandle nabasekhaya be-fiber optic transceivers emakethe, futhi imigqa yemikhiqizo yabo icebile kakhulu. Izinhlobo zama-fiber optic transceiver nazo zihlukile, ikakhulukazi zihlukaniswe ngama-rack-mounted optical transceivers, ama-transceiver optical wedeskithophu kanye ne-ca...

Ingabe i-optical fibre ingakwazi ukuguqula ikhebuli yenethiwekhi? I-Optical fiber iwuhlobo lwe-optical glass fiber, edlulisela amasignali okubona futhi ayikwazi ukuxhunywa ngokuqondile kukhebula yenethiwekhi. Idinga ukusebenzisa imishini yokuguqula ugesi wesithombe ukuze iguqule amasiginali okubona abe amasignali enethiwekhi. Ukukhethwa kwesithombe okujwayelekile...

I-100M optical fibre transceiver (eyaziwa nangokuthi i-100M photoelectric converter) iyisiguquli se-Ethernet esisheshayo. I-fiber optic transceiver ihambisana ngokugcwele namazinga e-IEEE802.3, IEEE802.3u, kanye ne-IEEE802.1d. Isekela izindlela ezintathu zokusebenza: i-duplex egcwele, i-half duplex, ne-adaptive. Gigabit opt...
