Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ubuchwepheshe be-FTTH (Fiber To The Home) busakazeka kabanzi, ne-China Telecom, i-China Mobile, i-China Unicom opharetha abathathu benethiwekhi yezokuxhumana sebeqedile ukuthunyelwa okuvuthiwe okukhulu, futhi njenge-ONU (optical). imodemu) isiphenduke ithuluzi elidingekayo endaweni yenethiwekhi yasekhaya.I-ONU yendabuko yamukela i-chip enkulu ehlanganisiwe, ebonakala ngokujikeleza okulula, ukusetshenziswa kwamandla aphansi kanye nokuthembeka okuphezulu. I-ONU yendabuko ayikwazanga ukuhlangabezana nezidingo zokukhiqiza nokuphila kwabantu, futhi i-ONU esebenza ngezindlela eziningi yaba khona.
Iyini i-ONU enemisebenzi eminingi, njengoba negama libonisa, kubuchwepheshe bokushintshashintsha bangempela, yengeze eziningi ezifana nesevisi yokugcina i-USB, isevisi ye-Voice over Internet Protocol IP based voice transmission, CATV (Community Antenna Television) Services, Imisebenzi ye-WIFI nolunye uchungechunge.
I-Shenzhen HDV Photoelectron Technology Ltd.(HDV) ingumkhiqizi wemishini ye-ONU ochwepheshe futhi ingumkhiqizi wemojula yokuxhumana ehlakaniphile, inkampani yethu okwamanje ithengisa izinhlobo ezahlukene zemishini yokuxhumana ephezulu naphansi, efana: isiguquli se-fiber media, switch Ethernet, imishini ye-OLT, imishini ye-ONU. nokunye.Uma ufuna ukwazi okwengeziwe ngobuchwepheshe bezokuxhumana, wamukelekile ukuthi usithinte nganoma yisiphi isikhathi.
I-AC multi-functional dual-frequency ONU iwumkhiqizo we-HGU (home gateway unit) oklanywe ngezixazululo ezihlukahlukene ze-FTTH, usebenzisa izinhlelo zokusebenza ze-FTTH zenkampani yenethiwekhi ukuze unikeze ukufinyelela kwebhizinisi ledatha ezinsizeni zokugcinwa kwe-USB, izinsiza zokudlulisa izwi ze-V o IP kanye Amasevisi e-CATV.Lo mkhiqizo we-ONU usekelwe kubuchwepheshe be-XPON obuvuthiwe, obuzinzile, obungabizi futhi obuphumelelayo.Futhi ungakwazi ukusekela i-EPON ne-GPON mode ukushintsha ngokuzenzakalelayo, lapho uxhumeka ku-EPON OLT noma i-GPON OLT, ingakwazi ukuzitholela futhi ishintshele Imodi ye-EPON ne-GPON.Ukusekela i-PPPOC / IPOE / imodi ye-IP emile kanye nemodi yokuhlanganisa, isekela imodi ye-IEEE802.11b/g/n/ac(2.4G ne-5G WiFi), izinga lokuxhumana kwe-WiFi lifika ku-1200Mbps/s.Inokwethenjelwa okuphezulu, ukuphathwa okulula, ukuguquguquka kokucushwa kanye nezici zokuqinisekisa zekhwalithi yesevisi (QoS), ukuhlangabezana nenethiwekhi ye-China Telecom passive optical ukufinyelela ubuchwepheshe be-EPON kanye ne-ITU-TG.I-GPON Technical Standard ye-984.X.Engakwazi ukuzivumelanisa nesimo samanje senethiwekhi esiyinkimbinkimbi nesishintshashintshayo.
