Phakathi kweentambo ze-OPGW ezibonakalayo ezisetyenziswe kwinkqubo yamandla yelizwe lam, iindidi ezimbini eziphambili, i-G.652 i-fiber ye-mode eyodwa eqhelekileyo kunye ne-G.655 i-non-zero dispersion shifted fiber, zezona zisetyenziswa kakhulu. Uphawu lwe-G.652 ye-fiber ye-mode eyodwa kukuba i-fiber dispersion incinci kakhulu xa i-wavelength yokusebenza i-1310nm, kwaye umgama wokuhambisa ukhawulelwe kuphela ngokunciphisa i-fiber. Ifestile ye-1310nm ye-fiber core ye-G.652 idla ngokusetyenziselwa ukuhambisa unxibelelwano kunye nolwazi oluzenzekelayo. I-G.655 i-fiber optical ine-dispersion ephantsi kwi-1550nm i-window ye-wavelength yengingqi kwaye idla ngokusetyenziselwa ukuhambisa ulwazi lokukhusela.
I-G.652A kunye ne-G.652B i-fibers optical fibers, eyaziwa ngokuba yi-fiber optical fibers eqhelekileyo, okwangoku zezona zisetyenziswa kakhulu iifiber zamehlo. Obona bude bugqwesileyo bokusebenza ngummandla we-1310nm, kwaye indawo ye-1550nm nayo ingasetyenziswa. Nangona kunjalo, ngenxa yosasazo olukhulu kule ndawo, umgama wothumelo ulinganiselwe malunga ne-70 ~ 80km. Ukuba ukuhanjiswa komgama omde kwisantya se-10Gbit / s okanye ngaphezulu kuyadingeka kwindawo ye-1550nm, , imbuyekezo ye-dispersion iyadingeka. I-G.652C kunye ne-G.652D iifayili ze-optical zisekelwe kwi-G.652A kunye ne-B ngokulandelanayo. Ngokuphucula inkqubo, i-attenuation kwingingqi ye-1350 ~ 1450nm iyancipha kakhulu, kwaye i-wavelength yokusebenza yandiswa ukuya kwi-1280 ~ 1625nm. Onke amabhanti akhoyo makhulu kuneentsinga eziqhelekileyo zemowudi enye. I-Fiber optics inyuke ngaphezu kwesiqingatha.
I-G.652D ifayibha ibizwa ngokuba yi-wavelength range eyandisiweyo yefiber yemowudi enye. Iimpawu zayo zifana ne-G.652B fiber, kwaye i-coefficient yokunciphisa i-coefficient ifana ne-G.652C fiber. Okokuthi, inkqubo inokusebenza kwibhendi ye-1360 ~ 1530nm, kunye noluhlu lwe-wavelength ekhoyo esebenzayo yi-G .652A, inokuhlangabezana neemfuno zophuhliso lwamandla amakhulu kunye ne-high-density wavelength division multiplexing iteknoloji kwiinethiwekhi zengingqi yemetropolitan. Inokugcina i-bandwidth enkulu enokubakho kuthungelwano lwe-optical network, gcina utyalo-mali lwentambo yokukhanya kunye nokunciphisa iindleko zokwakha. Ngaphezu koko, i-coefficient ye-polarization ye-dispersion ye-fiber ye-G.652D ingqongqo kakhulu kune-fiber ye-G.652C, eyenza ukuba ifaneleke ngakumbi ukuhanjiswa komgama omde.
I-essence yokusebenza ye-G.656 fiber iseyi-non-zero dispersion fiber. Umahluko phakathi kwe-G.656 i-fiber optical kunye ne-G.655 i-fiber optical kukuba (1) inomsebenzi obanzi wokusebenza. I-bandwidth yokusebenza ye-G.655 i-fiber optical yi-1530 ~ 1625nm (i-C + L band), ngelixa i-bandwidth yokusebenza ye-G.656 fiber optical yi-1460 ~ 1625nm (i-S + C + L band), kwaye inokwandiswa ngaphaya kwe-1460 ~ I-1625nm kwixesha elizayo, enokuthi ichwetheze ngokupheleleyo i-bandwidth enkulu ye-quartz glass fiber; (2) I-Dispersion slope incinci, enokunciphisa kakhulu ukusasazwa kwenkqubo ye-DWDM Iindleko zembuyekezo. I-G.656 i-fiber optical fiber yi-non-zero dispersion shifted optical fiber kunye ne-dispersion slope ye-zero ngokusisiseko kunye noluhlu lwe-wavelength esebenzayo egubungela ibhendi ye-S+C+L yokusasazwa kwe-broadband optical.
Ukuqwalasela ukuphuculwa kwexesha elizayo kweenkqubo zonxibelelwano, kucetyiswa ukuba kusetyenziswe iifayili ze-optical ze-subtype efanayo kwinkqubo efanayo. Ukususela kuthelekiso lweeparamitha ezininzi ezifana ne-chromatic dispersion coefficient, attenuation coefficient, kunye ne-PMDQ coefficient, kwicandelo le-G.652, i-PMDQ ye-G.652D fiber ingcono kakhulu kunezinye ii-subcategories kwaye inomsebenzi ongcono kakhulu. Ukuthathela ingqalelo izinto ezingabizi kakhulu, i-G .652D i-fiber optical iyona nto ingcono kakhulu kwi-OPGW cable optical cable. Ukusebenza okubanzi kwe-G.656 i-fiber optical nayo ingcono kakhulu kune-C.655 fiber optical. Kunconywa ukutshintsha i-G.655 i-fiber optical kunye ne-G.656 i-fiber optical kwiprojekthi.
