Iziguquli zevidiyo zefiber zemveli zisetyenziselwa usetyenziso lwe-point-to-point. I-fiber video converter ifakwe kuzo zombini iziphelo zefiber optical, ezifana neyona nto isetyenziswa ngokuqhelekileyo i-fiber Ethernet transceiver, esebenzisa i-fiber optical ukudibanisa inethiwekhi yekhompyutha kuzo zombini iziphelo. Kwaye kwiimeko ezifana nombane, ukugcinwa kwamanzi, njl. Ngokucacileyo, imo yothungelwano ithintelwe kakhulu. Ngeli xesha, iintambo ze-optical kunye nezixhobo zifunekayo ukwenza inethiwekhi yendandatho. Izixhobo ze-Optical zifuna i-terminal optical network ring: i-central yiconvergence, isignali yonxibelelwano ehambelanayo (ifowuni / ividiyo / i-Ethernet / i-serial port, njl.), igcina utyalo-mali lwentambo ye-optical kumlinganiselo omkhulu kwaye iphucula izinga lokusetyenziswa kwe-fiber core. , enengqiqo kwaye iyimfuneko kwizicelo ezibonakalayo.

Yintoni iRing Type Fiber Video Converter?

Ring Uhlobo lweFayibha Video Converter kufuneka izixhobo ubuncinane ezimbini okanye ngaphezulu izibuko optical, kwaye ezi zibuko kufuneka bakwazi ukuqaphela ukhuseleko lokuziphilisa. Xa nayiphi na i-node kwikhonkco ihluleka, inokukhetha ngokuzenzekelayo ezinye iindlela zokunxibelelana neziko ukuqinisekisa unxibelelwano oluqhelekileyo lwee-nodes ezingenasiphako.

Xa kuthelekiswa neteknoloji ye-analog yemveli, itekhnoloji yedijithali ineengenelo ezicacileyo kwiinkalo ezininzi. Kanye njengokuba itekhnoloji yedijithali ithatha indawo yetekhnoloji ye-analog kwiinkalo ezininzi, ukufakwa kwedijithali kwi- ring network transceivers optical ikwayindlela engenakuphepheka. Kukho iindlela ezimbini eziphambili zobugcisa zedijithali yevidiyo yekhonkco yenethiwekhi ye-optical transceiver: enye yiMPEGII yomfanekiso wokucinezela i-digital ring network fiber video converter, kwaye enye yi-digital-uncompressed network network fiber video converter.

Xa kuthelekiswa nesiguquli sevidiyo ye-analog yeringi yefiber yemveli, isiguquli sevidiyo yeringi yedijithali ineengenelo ezicacileyo:

I-1) Umgama omde wokuhambisa: ukuya kuthi ga kwi-80Km okanye nangaphezulu (120Km);
I-2) Inkxaso yevidiyo elahlekileyo yokuvuselela i-relay, ngoko ke imowudi yokuhanjiswa kwamanqanaba amaninzi ingasetyenziswa;
3) Ukuphazamiseka okuphantsi kokusingqongileyo kunye nomgangatho wothumelo oluphezulu;
I-4) Umthamo wesignali oxhaswayo unokufikelela kwiitshaneli ze-16 okanye ngaphezulu (iziteshi ze-32, iziteshi ze-64, iziteshi ze-128).
