Marka loo eego kala-soocidda kala duwan ee waqtiga horumarinta:
Qaybaha indhaha waxa loo qaybiyaa laba nooc: modules optical PON iyo modules indhaha dhaqameed.
Markaad isticmaalayso modules-dhaqameedyada soo jireenka ah: Habka gudbinta ishaarada indhaha waa bar-ilaa-dhibcood (P2P: hal gudbin ilaa hal), modules-yada waxaa loo isticmaalaa labo-labo (sida TX13RX15 iyo TX15RX13), oo loo isticmaalo hal fiber optic ah ama laba fiilooyinka indhaha ah gudbinta (tani waxa loo qaybin karaa hab-duplex ama simplex).
Luminta isku xirka fiber indhaha waxaa ka mid ah attenuation, kala firidhsan, khasaaraha gelinta xidhiidhka fiber, iwm kala firdhiso waxa sabab u ah fidinta garaaca wadnaha oo ay ugu wacan tahay heerka gudbinta kala duwan ee hirarka indhaha. Habka dhaqameedku wuxuu leeyahay masaafo dheer oo gudbin ah, ilaa 200km; qiimaha kharashka awgiis, waxaa yar loo isticmaalo shabakada gelitaanka, waxaana inta badan loo isticmaalaa shabakada laf dhabarta.
Marka la isticmaalayo PON modules indhaha, habka gudbinta calaamadaha indhaha waa dhibic-ilaa-multipoint (P2MP: ku gudbin karaa badan iyada oo loo marayo ODN), iyo modules aan loo isticmaalin labo-labo. Luminta isku xirka fiber indhaha waxaa ka mid ah attenuation, kala firidhsan, khasaaraha soo noqnoqda saamiga qaybinta, khasaaraha gelinta xidhiidhka fiber indhaha, iwm; Fogaanta gudbintu way ka gaaban tahay qaybaha dhaqanka, masaafadana waa 20km oo keliya; Inta badan waxaa loo isticmaalaa shabakadaha gelitaanka.
Kor ku xusan waa sharaxaada farqiga u dhexeeya PON modules indhaha iyo modules indhaha dhaqameed keenay Shenzhen HDV photoelectric Technology Co., Ltd. The alaabta module soo saaray cover shirkaddamodules fiber indhaha, modules Ethernet, modules transceiver fiber indhaha, modules helitaanka fiber indhaha, SSFP modules indhahaiyoFiber indhaha ee SFP, iwm. Alaabta cutubka sare waxay ku siin karaan taageero xaalado shabakadeed oo kala duwan. Kooxda R & D ee xirfadleyda ah iyo xoogga leh waxay ka caawin karaan macaamiisha arrimaha farsamada, iyo koox ganacsi oo feker iyo xirfad leh ayaa ka caawin kara macaamiisha inay helaan adeegyo tayo sare leh inta lagu jiro la-talinta kahor iyo shaqada soo-saarka kadib. Ku soo dhawoownala soo xidhiidhnooc kasta oo weydiin.
