Waxaa ka mid ah fiilooyinka indhaha ee OPGW loo isticmaalo nidaamka awoodda dalkayga, laba nooc oo xudun ah, G.652 fiber hal-mode caadiga ah iyo G.655 aan eber kala firdhiyey fiber, ayaa ah kuwa ugu isticmaalka badan. Sifada G.652 fiber hal-mode waa in kala firdhisanaanta fiber-ku aad u yar yahay marka mawjadda shaqadu ay tahay 1310nm, masaafada gudbinta ay xaddidan tahay oo kaliya hoos u dhaca fiber-ka. Daaqada 1310nm ee G.652 fiber core waxaa badanaa loo isticmaalaa gudbinta macluumaadka isgaarsiinta iyo otomaatiga. Fiber indhaha ee G.655 waxa uu leeyahay kala firdhisanaan hoose ee 1550nm daaqada ka shaqaynaysa mawjada dhererka waxaana badanaa loo isticmaalaa gudbinta macluumaadka ilaalinta.
G.652A iyo G.652B fiber optics, oo sidoo kale loo yaqaanno fiber optic-ka caadiga ah ee hal-mode, ayaa hadda ah kuwa ugu isticmaalka badan ee fiilooyinka indhaha. Mawjada shaqada ee ugu fiican waa aagga 1310nm, aagga 1550nm sidoo kale waa la isticmaali karaa. Si kastaba ha ahaatee, fidinta ballaaran ee aaggan awgeed, masaafada gudbintu waxay ku kooban tahay ilaa 70 ~ 80km. Haddii gudbinta masaafada fog ee heerka 10Gbit/s ama ka badan looga baahan yahay aagga 1550nm, , magdhowga kala firdhida ayaa loo baahan yahay. G.652C iyo G.652D fiilooyinka indhaha waxay ku salaysan yihiin G.652A iyo B siday u kala horreeyaan. By hagaajinta habka, attenuation ee gobolka 1350 ~ 1450nm si weyn loo dhimay, iyo hirarka hawlgalka waxaa la kordhiyey in 1280 ~ 1625nm. Dhammaan xargaha la heli karo way ka weyn yihiin fiilooyinka caadiga ah ee hal-hab. Fiber optics ayaa kordhay in ka badan kala badh.
Fiberka G.652D waxa loo yaqaan dhererka hirarka fidsan ee la fidiyay hal qaab. Aasaaskeedu asal ahaan waxay la mid yihiin fiber-ka G.652B, iyo isku-dheelitirnaanta attenuation waxay la mid tahay fiber G.652C. Taasi waa, nidaamku wuxuu ka shaqeyn karaa 1360 ~ 1530nm band, iyo xajmiga shaqada ee la heli karo waa G. Waxay kaydin kartaa baaxadda baaxadda shaqo ee baaxadda leh ee shabakadaha indhaha, waxay badbaadin kartaa maalgashiga fiilooyinka indhaha waxayna yaraynaysaa kharashaadka dhismaha. Waxaa intaa dheer, habka kala firdhinta isku-dhafka ee G.652D fiber ayaa aad uga adag kan G.652C fiber, taasoo ka dhigaysa mid ku habboon gudbinta fogaanta.
Nuxurka waxqabadka ee fiber G.656 ayaa wali ah fiber fidinta aan eber ahayn. Farqiga u dhexeeya G.656 fiber optic iyo G.655 fiber optic waa in (1) uu leeyahay baaxad ballaadhan oo hawleed. Xaddiga hawlgalka ee fiber optic G.655 waa 1530 ~ 1625nm (C + L band), halka xawaaraha hawlgalka ee fiber indhaha ee G.656 waa 1460 ~ 1625nm (S + C + L band), oo la ballaarin karaa in ka badan 1460 ~ 1625nm mustaqbalka, kaas oo si buuxda u taaban kara awoodda baaxadda weyn ee fiber galaas quartz; (2) Jiirada firidhsan ayaa ka yar, taas oo si weyn u yarayn karta kala firdhinta nidaamka DWDM kharashyada Magdhowga. Fiber indhaha G.656 waa kala firdhinta aan eber ahayn ee loo beddelay fiber indhaha ah oo leh jiirar kala firdhisan oo asal ahaan eber ah iyo baaxadda hirarka dhererka dhererka ee daboolaya band S+C+L ee gudbinta indhaha ee ballaaran.
Iyadoo la tixgelinayo casriyeynta mustaqbalka ee hababka isgaarsiinta, waxaa lagu talinayaa in la isticmaalo fiilooyinka indhaha ee isla nooca hoose ee isla nidaamka. Marka la barbardhigo qiyaasaha kala duwan sida iskudarka kala firdhisanaanta chromatic, coefficient attenuation coefficient, iyo PMDQ coefficient, ee qaybta G.652, PMDQ ee fiber G.652D aad ayuu uga fiican yahay qaybaha kale waxayna leedahay waxqabadka ugu fiican. Iyadoo la tixgelinayo arrimo kharash-ool ah, G .652D fiber indhaha ayaa ah doorashada ugu fiican ee fiilada indhaha ee OPGW. Waxqabadka dhamaystiran ee G.656 fiber optical sidoo kale aad ayuu uga fiican yahay kan C.655 fiber indhaha. Waxaa lagu talinayaa in lagu beddelo G.655 fiber optic ah oo leh G.656 fiber optical ee mashruuca.
