Dunida maanta, helitaanka xiriir internet oo la isku halayn karo ayaa ka muhimsan sidii hore. Taasi waa meesha 1550nm CATV Mini Fiber Optic Transmitter ka yimaado - loogu talagalay si gaar ah shabakadaha FTTH (Fiber To The Home), waxay bixisaa toosnaan iyo fidsanaan aad u fiican si loo hubiyo isku xirnaanta xawaaraha sare leh. Waxaan fahamsanahay muhiimadda ay leeyihiin qaybaha tayada sare leh, taas oo ah sababta badeecadaheenu u isticmaalaan qalab-qaadeha GaAs ee waxqabadka la xoojiyay. Luminta sare ee soo noqoshada fibre-ka-hal-habka ah waxay hubinaysaa inaad sida ugu fiican uga faa'iidaysato adeeggaaga internetka. Marka laga soo tago waxqabadka cajiibka ah, alaabadayadu waxay isticmaalaan tignoolajiyada qaylada aadka u hooseeya ee xidhiidhada la isku halayn karo.
Laysarada xirmada yar yar ee DFB coaxial waxay hubisaa in isku xirkaagu yahay mid xoogan oo deggan. Alaabtayadu maaha oo kaliya inay si fiican u shaqeeyaan, laakiin sidoo kale waxaa loogu talagalay iyada oo si sahlan loo rakibo maskaxda. Waxay leedahay cabbir yar iyo hab rakibid sahlan. Tilmaamaha korantada LED-ka ee cas macnaheedu waa inaad had iyo jeer ogaan doonto xaaladdeeda. Maalgelinta alaabtayada waxay la macno tahay maalgelinta mustaqbalka xidhiidhka internetka ee gurigaaga. Aan kaa caawino inaad ku xidhnaato adeeg degdeg ah oo la isku halayn karo. Fadlan booqo mareegahayaga wixii macluumaad dheeraad ah, wixii su'aalo ah, fadlan xor u noqo inaad nala soo xidhiidho.
