Horumarka degdega ah ee sayniska iyo tignoolajiyada, tignoolajiyada FTTH (Fiber To The Home Fiber to the Home) ayaa si ballaaran loo faafiyay. Shabakadda isgaadhsiinta ee ay u badan yihiin China Telecom, China Mobile iyo China Unicom ayaa soo gebagebaysay hawlgelin ballaaran oo bisil. Sida gudbiyaha fiber-ka ee tignoolajiyada guriga, bisad indhaha ah (modem optical) waxay noqotay qalab lagama maarmaan u ah dhismaha deegaanka shabakada guriga. Bisadda indhaha ee dhaqameedku waxay qabataa jajabyo isku dhafan oo ballaaran, kuwaas oo leh sifooyinka wareegyada fudud, isticmaalka tamarta yar, iyo kalsoonida sare. Iyadoo jawiga isticmaalka shabakada uu sii kordhayo kakan, bisadaha indhaha ee dhaqameedku ma awoodaan inay daboolaan wax soo saarka dadka iyo baahiyaha maalinlaha ah, waxaana soo baxay bisadaha indhaha ee kala duwan.
Waa maxay bisad indhaha ah oo kala duwan? Sida magacu soo jeediyo, iyadoo lagu salaynayo habaynta asalka ah iyo tignoolajiyada dib u habeynta bisadaha indhaha, adeegyo taxane ah ayaa lagu soo daray, sida adeegyada kaydinta USB, adeegyada VoIP (Voice over Internet Protocol based voice transfer), CATV (Community Antenna Television) ) adeegyada, hawlaha WIFI, iyo wixii la mid ah.
Shenzhen Haidiwei Optoelectronics (HDV) waa soo-saare xirfad lehONUQalabka bisadaha indhaha iyo qaybaha isgaarsiinta ee caqliga leh. Shirkaddeennu waxay hadda iibisaa aaladaha isgaadhsiinta ee kala duwan ee leh xidhiidhyada kor iyo hoosba, sida transceivers fiber optic, furayaasha Ethernet,OLTqalabka,ONUqalabka, iyo wixii la mid ah. Haddii aad jeclaan lahayd inaad wax badan ka barato aqoonta tignoolajiyada isgaarsiinta, fadlan xor u noqo inaad la xiriirto shirkadeena.
Bisadda indhaha ee labada kooxood ee AC dual-ka badan leh waa badeecad HGU ah (cutubka albaabka guriga) oo loogu talagalay xalal kala duwan oo FTTH ah. Waxay isticmaashaa codsiyada FTTH heerka side si ay u bixiso adeega xogta helitaanka adeegyada kaydinta USB, adeegyada gudbinta codka VoIP iyo adeegyada CATV. Alaabta bisadaha indhaha waxay ku salaysan tahay tignoolajiyada XPON ee qaangaadhka ah, degan, iyo kharash-oolku. Waxayna taageertaa beddelka tooska ah ee u dhexeeya hababka EPON iyo GPON. Marka ay ku xiran tahay EPONOLTama GPONOLT, waxay si toos ah u ogaan kartaa iyobeddeloEPON iyo qaababka GPON. Waxay taageertaa hab-socodka iyo isku xidhka hababka sida PPPOC/IPOE/static IP, waxay taageertaa IEEE802.11b/g/n/ac (2.4G iyo 5GWiFi), iyo heerka isgaarsiinta WiFi wuxuu gaari karaa 1200Mbps/s. Waxay leedahay sifooyinka isku halaynta sare, maaraynta fudud, qaabeynta dabacsan, iyo hubinta tayada wanaagsan ee adeegga (QoS), waxayna la kulmeysaa Shiinaha Telecom ee shabakada indhaha ee EPON helitaanka tignoolajiyada iyo ITU-TG.984. Heerarka tignoolajiyada GPON. La qabso jawiga shabakada ee adag oo mar walba isbedelaya.
