Ngokohlelo olwahlukeneyo lwexesha lophuhliso:
Iimodyuli ze-Optical zihlukaniswe zibe zimbini iintlobo: iimodyuli ze-PON kunye neemodyuli ze-optical zendabuko.
Xa usebenzisa iimodyuli zendabuko ye-optical: Imowudi yokuhanjiswa kwesignali ye-optical i-point-to-point (P2P: enye idlulise ukuya kwelinye), iimodyuli zisetyenziselwa ngababini (ezifana ne-TX13RX15 kunye ne-TX15RX13), kwaye zisebenzisa i-fiber optical okanye i-fiber optical fibers. ugqithiso (oku kunokwahlulwa kwimowudi ye-duplex okanye elula).
Ilahleko ye-Optical fiber link iquka ukuthomalalisa, ukusasazwa, ilahleko yokufaka ifayibha, njl. njl. Ukusasazwa kubangelwe kukwanda kwepulse ngenxa yamazinga awohlukeneyo osulelo lwamaza okukhanya okubonakalayo. Imodyuli yendabuko inomgama omde wokuhanjiswa, ukuya kuthi ga kwi-200km; ngenxa yeendleko zexabiso, ayisetyenziswanga kancinci kuthungelwano lofikelelo, kwaye isetyenziswa ikakhulu kumnatha womqolo.
Xa usebenzisa i-PON iimodyuli ze-optical, indlela yokudlulisa izibonakaliso ze-optical point-to-multipoint (P2MP: inokudlulisa amaninzi nge-ODN), kwaye iimodyuli azisetyenziswanga ngababini. Ilahleko yekhonkco yefiber ye-Optical ibandakanya ukuncipha, ukusabalalisa, ukulahleka komlinganiselo wokwahlulahlula, ukulahleka kokufakwa koxhumo lwefiber optical, njl.; umgama wokuhambisa umfutshane kuneemodyuli zendabuko, kwaye umgama u-20km kuphela; isetyenziswa ikakhulu kuthungelwano lofikelelo.
Oku ngasentla yinkcazo yomahluko phakathi kweemodyuli zePON kunye neemodyuli zemveli zamehlo eziziswa nguShenzhen HDV photoelectric Technology Co., Ltd.Imveliso yemodyuli eveliswe yikhava yenkampani.iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl. Ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa. Wamkelekile kuweQhagamshelana nathikulo naluphi na uhlobo lombuzo.
