Phakathi kwezintambo ezibonakalayo ze-OPGW ezisetshenziswa kusistimu yamandla yezwe lami, izinhlobo ezimbili eziyinhloko, i-G.652 i-fibre yemodi eyodwa evamile kanye ne-G.655 i-non-zero dispersion shifted fiber, yizo ezisetshenziswa kakhulu. Isici se-G.652 ye-fiber yemodi eyodwa ukuthi i-fiber dispersion incane kakhulu uma ubude be-waveleng obusebenzayo bungu-1310nm, futhi ibanga lokudlulisela lilinganiselwe kuphela ukuncishiswa kwefayibha. Iwindi le-1310nm le-G.652 fiber core livame ukusetshenziselwa ukudlulisa ulwazi lokuxhumana nolwazi oluzenzakalelayo. I-G.655 i-optical fiber inokusabalalisa okuphansi endaweni ye-wavelength yewindi engu-1550nm futhi ngokuvamile isetshenziselwa ukudlulisa ulwazi lokuvikela.
I-G.652A kanye ne-G.652B imicu yokubona, eyaziwa nangokuthi imicu ye-optical yemodi eyodwa evamile, okwamanje ayimicu esetshenziswa kakhulu ebonakalayo. Ubude bayo obufanele bokusebenza buyindawo engu-1310nm, futhi indawo engu-1550nm nayo ingasetshenziswa. Kodwa-ke, ngenxa yokuhlakazeka okukhulu kule ndawo, ibanga lokudlulisela lilinganiselwe cishe ku-70 ~ 80km. Uma ukudluliselwa kwebanga elide ngesilinganiso esingu-10Gbit/s noma ngaphezulu kudingekile endaweni engu-1550nm, , isinxephezelo sokuhlakazeka siyadingeka. I-G.652C kanye ne-G.652D ama-optical fibers asekelwe ku-G.652A no-B ngokulandelanayo. Ngokuthuthukisa inqubo, ukuncipha endaweni ye-1350 ~ 1450nm kuncishiswe kakhulu, futhi ubude be-waveleng obusebenzayo bunwetshwa ku-1280 ~ 1625nm. Wonke amabhendi atholakalayo makhulu kunemicu evamile yemodi eyodwa. I-Fiber optics ikhuphuke ngaphezu kwesigamu.
I-G.652D ifayibha ibizwa nge-wavelength range enwetshiwe yefibre yemodi eyodwa. Izici zayo ngokuyisisekelo ziyafana ne-G.652B fiber, futhi i-coefficient yokunciphisa iyafana ne-G.652C fiber. Okusho ukuthi, isistimu ingasebenza kubhendi engu-1360 ~ 1530nm, futhi ububanzi obukhona be-wavelength obusebenzayo yi-G .652A, ingahlangabezana nezidingo zokuthuthukiswa komthamo omkhulu kanye nobuchwepheshe bokuhlukaniswa kwe-wavelength ye-multiplexing kumanethiwekhi endawo yedolobha elikhulu. Ingagcina umkhawulokudonsa omkhulu ongasebenza wamanethiwekhi optical, yonge ukutshalwa kwezimali kwekhebula le-optical futhi yehlise izindleko zokwakha. Ngaphezu kwalokho, i-coefficient yokusabalalisa yemodi ye-polarization ye-fiber ye-G.652D iqinile kakhulu kunaleyo ye-G.652C fiber, okwenza ifaneleke kakhulu ukudluliselwa kwebanga elide.
I-essence yokusebenza ye-G.656 fibre kuseyifayibha yokuhlakazeka engeyona iqanda. Umehluko phakathi kwe-G.656 optical fiber ne-G.655 fiber optical ukuthi (1) inomkhawulokudonsa obanzi wokusebenza. Umkhawulokudonsa osebenzayo we-G.655 optical fibre yi-1530~1625nm (C+L band), kuyilapho umkhawulokudonsa osebenzayo we-G.656 optical fiber ingu-1460~1625nm (S+C+L band), futhi unganwetshwa ukudlula u-1460~ 1625nm ngokuzayo, engathinta ngokugcwele amandla omkhawulokudonsa omkhulu we-quartz glass fiber; (2) I-slope yokusabalalisa incane, enganciphisa kakhulu ukuhlakazeka kohlelo lwe-DWDM Izindleko zesinxephezelo. I-G.656 i-fiber optical iyi-non-zero optical fibre eguquliwe ene-dispersion slope enguziro ngokuyisisekelo kanye nobubanzi be-wavelength obusebenzayo obumboza ibhendi ye-S+C+L yokudluliswa kwe-broadband optical.
Uma ucabangela ukuthuthukiswa kwesikhathi esizayo kwezinhlelo zokuxhumana, kunconywa ukusebenzisa imicu ye-optical ye-subtype efanayo ohlelweni olufanayo. Kusukela ekuqhathanisweni kwamapharamitha amaningi njenge-chromatic dispersion coefficient, attenuation coefficient, kanye ne-PMDQ coefficient, esigabeni se-G.652, i-PMDQ ye-G.652D fiber ingcono kakhulu kunezinye izigaba ezingaphansi futhi inokusebenza okungcono kakhulu. Uma kucatshangelwa izici ezonga kakhulu, i-G .652D i-fiber optical iyinketho engcono kakhulu yentambo yokubona ye-OPGW. Ukusebenza okuphelele kwe-G.656 optical fiber nakho kungcono kakhulu kunokwe-C.655 fiber optical. Kunconywa ukufaka esikhundleni se-G.655 fibre optical ne-G.656 fiber optical kuphrojekthi.
