Ngokuthuthuka kwesayensi nobuchwepheshe, isivinini sokwaziswa kwasemadolobheni siyakhula, futhi izidingo zobuchwepheshe bezokuxhumana ziya ngokuya ziba phezulu. Imicu yokubona iya ngokuya ithandwa kakhulu kwezokuxhumana ngenxa yezinzuzo zayo zokudluliswa okusheshayo...

Umsebenzi wemojula ye-optical ukuguqulwa kwe-photoelectric. Isiphetho sokudlulisa siguqula isignali kagesi ibe isignali yokubona. Ngemva kokudlulisela nge-fiber optical, isiphetho sokwamukela siguqula isignali ye-optical ibe isignali kagesi. Ihlukaniswe ikakhulukazi: SFP, SFP+,...

Imishini ethile: i-transceiver optical, i-optical fibre transceiver, switch, ikhadi lenethiwekhi ye-optical, i-optical fibre router, i-optical fiber high-speed dome, i-base station, i-repeater, njll. Amabhodi e-optical port emishini yokudlulisa ejwayelekile afakwe amamojula ahambisanayo optical. Ukuze uthole imininingwane...

Ukunemba okuphezulu kwebhodi lesifunda kubhekisela ekusetshenzisweni kobubanzi/isikhala somugqa ocolekile, izimbobo ezincane, ububanzi bendandatho encane (noma ukungabi nobubanzi bendandatho), kanye nezimbobo ezigqitshiwe nezingaboni ukuze kuzuzwe ukuminyana okuphezulu. Ukunemba okuphezulu kubhekisela kumphumela othi "mncane, omncane, omncane, omncane" uzoletha ...

I-PON (Passive Optical Network) iyinethiwekhi ye-passive Optical network, okusho ukuthi i-ODN (inethiwekhi yokusabalalisa optical) phakathi kwe-OLT (optical line terminal) kanye ne-ONU (optical network unit) ayinayo into esebenzayo, futhi isebenzisa kuphela imicu yokubona. kanye nezingxenye ze-passive. I-PON yamukela ikakhulukazi...

I-Optical fiber transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-fiber converter ezindaweni eziningi. Umkhiqizo uvame ukusetshenziswa endaweni yangempela yenethiwekhi lapho ...
