Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ubuchwepheshe be-FTTH (Fiber To The Home Fiber to the Home) buye basakazwa kabanzi.Inethiwekhi yokuxhumana ebuswa yi-China Telecom, i-China Mobile kanye ne-China Unicom isiqede ukuthunyelwa kwabantu abavuthiwe ngezinga elikhulu.Njengomthwali wefayibha kubuchwepheshe basekhaya, ikati elibonakalayo (imodemu yokubona) seliyithuluzi elibalulekile lokwakha indawo yenethiwekhi yasekhaya.Ikati elivamile le-optical lithatha ama-chips amakhulu ahlanganisiwe, anezici zamasekhethi alula, ukusetshenziswa kwamandla okuphansi, nokuthembeka okuphezulu.Ngokukhula kwemvelo yokusetshenziswa kwenethiwekhi eyinkimbinkimbi, amakati endabuko optical awasakwazi ukuhlangabezana nokukhiqizwa kwabantu kanye nezidingo zansuku zonke, futhi sekuvele amakati asebenza ngezinto eziningi.
Liyini ikati le-multifunctional optical?Njengoba igama liphakamisa, ngesisekelo sobuchwepheshe bokuqala bokuguquguquka nokwehliswa kwe-optical cats, kuye kwanezelwa uchungechunge lwezinsizakalo, njengezinsizakalo zokugcina i-USB, izinsizakalo zeVoIP (Voice over Internet Protocol based voice transmission), CATV (Community Antenna Television). ) amasevisi, imisebenzi ye-WIFI, njalonjalo.
I-Shenzhen Haidiwei Optoelectronics (HDV) ingumkhiqizi ochwepheshe weI-ONUimishini yekati ye-optical kanye namamojula okuxhumana ahlakaniphile.Inkampani yethu njengamanje ithengisa amadivaysi ezokuxhumana ahlukahlukene anokuxhumana phezulu naphansi, njengama-fiber optic transceivers, amaswishi e-Ethernet, amadivayisi we-OLT,I-ONUamadivaysi, nokunye.Uma ungathanda ukufunda okwengeziwe ngolwazi lobuchwepheshe bezokuxhumana, sicela ukhululeke ukuxhumana nenkampani yethu.
Ikati elinjalo elisebenza ngezinto eziningi le-AC dual band optical liwumkhiqizo we-HGU (home gateway unit) oklanywe ngezixazululo ezihlukahlukene ze-FTTH.Isebenzisa izinhlelo zokusebenza ze-FTTH zenkampani yenethiwekhi ukuze inikeze ukufinyelela kwesevisi yedatha ngamasevisi esitoreji se-USB, izinsizakalo zokudlulisa ngezwi le-VoIP kanye nezinsizakalo ze-CATV.Lo mkhiqizo wekati obonakalayo usekelwe kubuchwepheshe be-XPON obuvuthiwe, obuzinzile, futhi obungabizi kakhulu.Futhi isekela ukushintsha okuzenzakalelayo phakathi kwezindlela ze-EPON ne-GPON.Uma ixhunywe ku-EPON OLT noma i-GPON OLT, ikwazi ukuzitholela futhi ishintshele kumamodi e-EPON ne-GPON.Isekela izindlela zokuthungatha nokuhlanganisa njenge-PPPOC/IPOE/static IP, isekela izindlela ze-IEEE802.11b/g/n/ac (2.4G ne-5GWiFi), futhi amazinga okuxhumana kwe-WiFi angafinyelela ku-1200Mbps/s.Inezici zokuthembeka okuphezulu, ukuphatha okulula, ukucushwa okuguquguqukayo, kanye nokuqinisekiswa kwekhwalithi enhle yesevisi (QoS), futhi ihlangabezana nokufinyelela kobuchwepheshe benethiwekhi ye-China Telecom ye-EPON kanye ne-ITU-TG.984.Izindinganiso zobuchwepheshe ze-X GPON.Zijwayelane nesimo senethiwekhi esiyinkimbinkimbi nesishintsha njalo.
