Iziguquli zevidiyo ze-fiber zendabuko zisetshenziselwa izinhlelo zokusebenza ze-point-to-point. I-fiber video converter ifakwe kuzo zombili iziphetho ze-optical fibre, njenge-transceiver ye-fiber Ethernet esetshenziswa kakhulu, esebenzisa i-optical fiber ukuxhuma inethiwekhi yekhompyutha kuzo zombili iziphetho. Futhi ezikhathini ezinjengogesi, ukongiwa kwamanzi, njll. Ngokusobala, imodi yokuxhumana ikhawulelwe kakhulu. Ngalesi sikhathi, izintambo ezibonakalayo nezinto zokusebenza ziyadingeka ukuze kwakhiwe inethiwekhi yendandatho. Imishini yokubona idinga itheminali yokubona yenethiwekhi: emaphakathi ukuhlangana, isignali yokuxhumana ehambisanayo (ifoni/ividiyo/i-Ethernet/imbobo ye-serial, njll.), ilondoloza ukutshalwa kwezimali kwentambo yokubona ngezinga elikhulu futhi ithuthukisa izinga lokusetshenziswa kwe-fiber core. , enengqondo futhi edingekayo ekusebenzeni okungokoqobo.

Iyini iRing Type Fiber Video Converter?

I-Ring Type Fiber Video Converter idinga okokusebenza okungenani okunamachweba abonakalayo amabili noma ngaphezulu, futhi lezi zimbobo kufanele zikwazi ukubona ukuvikeleka kokuziphilisa. Uma noma iyiphi i-node ekusixhumanisi ihluleka, ingakhetha ngokuzenzakalelayo eminye imizila ukuxhumana nesikhungo ukuze kuqinisekiswe ukuxhumana okuvamile kwama-node angenawo amaphutha.

Uma kuqhathaniswa nobuchwepheshe be-analog bendabuko, ubuchwepheshe bedijithali bunezinzuzo ezisobala ezicini eziningi. Njengoba nje ubuchwepheshe bedijithali buthatha indawo yobuchwepheshe be-analog emikhakheni eminingi, ukwenziwa kwedijithali kwama-transceivers optical network ring nakho kuwumkhuba ongenakugwemeka. Kunezindlela ezimbili zobuchwepheshe eziyinhloko ze-digital video ring network optical transceiver: eyodwa iyi-MPEGII image compression digital ring network fiber video converter, kanti enye iyi-digital-digital uncompressed network fiber video converter.

Uma kuqhathaniswa nesiguquli sevidiyo se-analog esiyindandatho yenethiwekhi ye-fiber, isiguquli sevidiyo yenethiwekhi yendandatho yedijithali sinezinzuzo ezisobala:

1) Ibanga elide lokudlulisela: kufika ku-80Km noma ngisho nangaphezulu (120Km);
2) Sekela ividiyo yokuvuselelwa kabusha okungalahleki, ngakho-ke imodi yokudlulisa enamazinga amaningi ingasetshenziswa;
3) Ukuphazanyiswa kwemvelo okuphansi kanye nekhwalithi ephezulu yokudlulisela;
I-4) Umthamo wesiginali osekelwayo ungafinyelela iziteshi eziyi-16 noma ngaphezulu (iziteshi ezingama-32, iziteshi ezingama-64, iziteshi eziyi-128).
