I-Optical fiber transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye nemiqondiso yokubona ekude. Yahlulwe kakhulu ibe yi-fiber optical transceivers kunye ne-dual-fiber optical transceivers ngokweemfuno zabo zeNex...

Iingxaki kunye nezisombululo ezijongene nokufakela kunye nokusetyenziswa kwee-transceivers ze-fiber optical Isinyathelo sokuqala: okokuqala jonga ukuba ukukhanya kwesalathisi se-fiber optical transceiver okanye imodyuli ye-optical kunye ne-twisted pair port indicator ukukhanya kuvuliwe? 1. Ukuba izibuko (FX) isalathisi se A tr...

I-EPON yitekhnoloji yePON esekwe kwi-Ethernet. Isebenzisa iteknoloji ye-PON kwinqanaba lomzimba, i-Ethernet protocol kwi-data link layer, ukufikelela kwe-Ethernet usebenzisa i-PON topology, kunye nokufikelela kwinkonzo epheleleyo kwidatha, ilizwi, kunye nevidiyo usebenzisa i-fiber optical. Inkcazo yemveliso ye-EPON: I-EPON ihambisa kwaye ifumana ...

I-optical splitter yenye yezixhobo ezibalulekileyo ze-passive kwikhonkco ye-fiber optical, kwaye ikakhulu idlala indima yokwahlula. Ngokuqhelekileyo isetyenziswa kwi-terminal ye-OLT ye-optical line kunye ne-terminal yenethiwekhi ye-ONU ye-passive network optical ukuqonda ukwahlula isignali yokukhanya. I-op...

Okwangoku, ngokwetekhnoloji ye-fiber optical access network, ufikelelo lwe-narrowband luthatyathelwa indawo lufikelelo lwebroadband, kwaye ekugqibeleni ifayibha ikhaya liyafezekiswa. I-broadband optical fiber yenethiwekhi yofikelelo iba yinto engenakuthintelwa, kwaye itekhnoloji ye-PON iya kuba yeyona ndawo iphambili yobugcisa ...

Imodyuli ye-PON yimodyuli ye-optical ephezulu yokusebenza esetyenziswa kwinkqubo ye-PON, Ebhekiselwa kuyo njengemodyuli ye-PON,Thobela i-ITU-T G.984.2 umgangatho kunye nesivumelwano semithombo emininzi (MSA),Isebenzisa ubude obuhlukeneyo bokuthumela kunye nokufumana iimpawu phakathi kweOLT (I-Optical Line Terminal) kunye ne-ONT (i-Optical Network Terminal). Ty...
