I-optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-fiber converter ezindaweni eziningi. Imikhiqizo ivamise ukusetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumbozwa khona futhi imicu yokubona kufanele isetshenziselwe ukunweba ibanga lokudlulisela, futhi ngokuvamile ibekwe kuhlelo lokusebenza lwesendlalelo sokufinyelela samanethiwekhi endawo yedolobha elikhulu.

Indima yama-fiber optic transceivers

Ama-transceivers e-Fiber optic ngokuvamile asetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumbozwa futhi imicu yokubona kufanele isetshenziselwe ukunweba ibanga lokudlulisela. Ngesikhathi esifanayo, baphinde babamba iqhaza elikhulu ekusizeni ukuxhuma imayela lokugcina lemigqa yefiber optical kumanethiwekhi ezindawo zedolobha elikhulu kanye namanethiwekhi angaphandle. Indima ye. Umsebenzi we-fiber optic transceiver ukuguqula isignali kagesi esifuna ukuyithumela kusignali yokubona bese siyithumela ngaphandle. Ngesikhathi esifanayo, ingaguqula isignali ye-optical eyamukelwe ibe isignali kagesi futhi iyifake ekugcineni kwethu kokuthola.

Ukuhlukaniswa kwei-fiber optic transceivers

I-1.Imodi eyodwa ye-fiber optic transceiver: ibanga lokudlulisela ukusuka kumakhilomitha angama-20 ukuya kumakhilomitha ayi-120.

I-2.I-Multimode fiber optic transceiver: ibanga lokudlulisela lamakhilomitha angu-2 ukuya kumakhilomitha angu-5.

Isibonelo, amandla okudlulisa we-5km fiber optic transceiver ngokuvamile aphakathi kuka -20 kanye -14db, futhi ukuzwela okutholayo kungu-30db, kusetshenziswa ubude be-waveleng buka-1310nm; kuyilapho amandla okudlulisa e-transceiver ye-fiber optic engu-120km ngokuvamile ephakathi kuka--5 no-0dB, kanye nokuzwela kokwamukela Ku--38dB, sebenzisa ubude begagasi obungu-1550nm.

Izici ze-fiber optic transceivers

Ama-transceivers e-Fiber optic ngokuvamile anezimpawu eziyisisekelo ezilandelayo:

1. Nikeza ngokudluliswa kwedatha yokubambezeleka okuphansi kakhulu.

2. Obala ngokugcwele kuphrothokholi yenethiwekhi.

3. Sebenzisa i-chip ye-ASIC ezinikele ukuze uthole ukudluliselwa kwesivinini somugqa wedatha. I-Programmable ASIC igxilisa imisebenzi eminingi ku-chip eyodwa, futhi inezinzuzo zokuklama okulula, ukwethembeka okuphezulu, kanye nokusetshenziswa kwamandla okuphansi, okungenza imishini ikwazi ukuthola ukusebenza okuphezulu kanye nezindleko eziphansi.

4. Imishini yohlobo lwe-rack inganikeza umsebenzi oshintshwayo oshisayo ukuze ulungiswe kalula kanye nokuthuthukiswa okungaphazamiseki.

5. Izinto zokuphatha inethiwekhi zingahlinzeka ngemisebenzi efana nokuxilongwa kwenethiwekhi, ukuthuthukisa, umbiko wesimo, umbiko wesimo esingavamile kanye nokulawula, futhi ingahlinzeka ngohlelo lokusebenza oluphelele kanye nelogi ye-alamu.

6. Izinto eziningi zokusebenza zisebenzisa idizayini yokuphakelwa kukagesi engu-1+1, isekela i-ultra-wide power supply voltage, futhi ibona ukuvikelwa kokunikezwa kwamandla kanye nokushintsha okuzenzakalelayo.

7. Sekela izinga lokushisa lokusebenza elibanzi kakhulu.

8. Sekela ibanga eliphelele lokudlulisela (amakhilomitha angu-0~120).

Izinzuzo ze-fiber optic transceivers

Uma kukhulunywa ngama-transceivers e-fiber optic, abantu bavame ukuqhathanisa ngokungenakugwenywa ama-transceiver e-fiber optic nawoamaswishingamachweba optical. Okulandelayo ikakhulukazi kukhuluma ngezinzuzo zama-fiber optic transceivers ngaphezu kwe-optical portamaswishi.

Okokuqala, intengo ye-fiber optic transceivers plus evamileamaswishiishibhile kakhulu kune-opticalamaswishi, ikakhulukazi ezinye ze-opticalamaswishiizolahlekelwa imbobo kagesi eyodwa noma eziningana ngemva kokwengeza amamojula optical, angenza opharetha ngokwezinga elikhulu Yehlise ukutshalwa kwezimali kwangaphambili.

Okwesibili, njengoba iningi lamamojula optical weamaswishiayinayo indinganiso ehlanganisiwe, uma amamojula optical ebonakalisiwe, adinga ukushintshwa ngamamojula afanayo avela kumkhiqizi wokuqala, okuletha inkinga enkulu ekunakekeleni kamuva. yabakhiqizi abahlukene be-fiber optic transceivers, ngakho-ke uma yonakele, ingashintshwa ngemikhiqizo yabanye abakhiqizi, okulula kakhulu ukuyigcina.

Ngaphezu kwalokho, ama-transceivers e-fiber optic anemikhiqizo ephelele kune-optical portamaswishingokwebanga lokudlulisela. Yiqiniso, i-opticalshintshafuthi inezinzuzo ezicini eziningi, njengokuphatha okuhlangene kanye nokuphakelwa kwamandla okuhlangene.
