I-Fiber media converter iyithuluzi elibalulekile ekudluliseni idatha yenethiwekhi. Ngakho-ke yini i-fiber media converter? Yiziphi izingxenye ze-fiber media converter? Iyiphi indima edlalwa i-fiber media converter ohlelweni lokudluliswa kwedatha?

I-fiber media converter ihlanganisa amamojula amathathu ayisisekelo asebenzayo: i-chip ye-photoelectric media conversion chip, isikhombimsebenzisi sesignali ye-optical (imoduli ehlanganisiwe ye-transceiver) kanye ne-interface yesignali kagesi (RJ45). Uma ifakwe imisebenzi yokuphatha inethiwekhi, ihlanganisa neyunithi yokucubungula ulwazi lokuphathwa kwenethiwekhi.

I-fiber media converter iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amade namasiginali okubona amabanga amade. Ibizwa nangokuthi i-photoelectric converter (I-Fiber Converter) ezindaweni eziningi. Umkhiqizo uvame ukusetshenziswa endaweni yangempela yenethiwekhi lapho ikhebula le-Ethernet lingakwazi ukumboza futhi i-fiber optical kufanele isetshenziselwe ukunweba ibanga lokudlulisela, futhi ngokuvamile ibekwe kuhlelo lokusebenza lwesendlalelo sokufinyelela senethiwekhi yendawo yedolobha elikhulu elibanzi; ngesikhathi esifanayo, kusiza ukuxhuma umugqa wokugcina wamamayela wefiber optical endaweni yedolobha elikhulu. I-inthanethi kanye nenethiwekhi yangaphandle nakho kudlale indima enkulu.

Kwamanye amabhizinisi amakhulu, i-optical fibre isetshenziswa ngokuqondile njengendawo yokudlulisa ukuze kusungulwe inethiwekhi yomgogodla ngesikhathi sokwakhiwa kwenethiwekhi, kanti indawo yokudlulisela ye-LAN yangaphakathi ngokuvamile intambo yethusi. Ungakubona kanjani ukuxhumana phakathi kwe-LAN nenethiwekhi ye-optical fiber backbone? Lokhu kudinga izimbobo ezihlukene kanye nokuguqula okuhlukile phakathi komugqa kanye nemicu yokubona ehlukile futhi kuqinisekise ikhwalithi yesixhumanisi. Ukuvela kwama-transceivers e-fiber optical kuguqula amasignali kagesi ne-optical of the pair esontekile komunye nomunye, ukuqinisekisa ukudluliswa okushelelayo kwamaphakethe wedatha phakathi kwamanethiwekhi amabili. Ngesikhathi esifanayo, inweba umkhawulo webanga lokudlulisela lenethiwekhi ukusuka kumamitha ayi-100 wezintambo zethusi ukuya ngaphezu kwamakhilomitha ayi-100 (i-fiber yemodi eyodwa).

Yiziphi izici eziyisisekelo zama-fiber media converters:

1. Obala ngokugcwele kuphrothokholi yenethiwekhi.

2. Nikeza ngokudluliswa kwedatha yokubambezeleka okuphansi kakhulu.

3. Sekela izinga lokushisa elibanzi kakhulu lokusebenza.

4. 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.

5. Imishini yokuphatha inethiwekhi ingahlinzeka ngemisebenzi efana nokuxilongwa kwenethiwekhi, ukuthuthukiswa, umbiko wesimo, umbiko wesimo esingavamile nokulawula, futhi ingahlinzeka ngelogi yokusebenza ephelele kanye nelogi ye-alamu.

6. Imishini yohlobo lwe-rack inganikeza umsebenzi oshintshwayo oshisayo ukuze ulungiswe kalula kanye nokuthuthukiswa okungaphazanyiswa.

7. Isekela ibanga eliphelele lokudlulisela (0～120km).

8. Izinto zokusebenza ngokuvamile zamukela idizayini yokuphakelwa kukagesi engu-1+1, isekela amandla kagesi abanzi kakhulu, futhi ibona ukuvikelwa kwamandla nokushintsha okuzenzakalelayo.
