Pakati peOPGW optical cables inoshandiswa munyika yangu yemagetsi, maviri makuru marudzi, G.652 yakajairika single-mode fiber uye G.655 isiri zero dispersion shifted fiber, ndiyo inonyanya kushandiswa. Unhu hweG.652 single-mode fiber ndeyokuti fiber dispersion iduku zvikuru apo kushanda kwewavelength iri 1310nm, uye kureba kwekufambisa kunongogumira nekuderedzwa kwefiber. Iwindo re1310nm reG.652 fiber core rinowanzoshandiswa kutumira kutaurirana uye ruzivo rwemagetsi. G.655 optical fiber ine yakaderera dispersion mu 1550nm hwindo inoshanda wavelength region uye inowanzo shandiswa kutumira mashoko ekudzivirira.
G.652A uye G.652B optical fibers, inozivikanwawo seyakajairika-mode optical fibers, pari zvino ndiyo inonyanya kushandiswa optical fibers. Yayo yakakwana yekushanda wavelength ndiyo 1310nm nharaunda, uye iyo 1550nm nzvimbo inogona zvakare kushandiswa. Nekudaro, nekuda kwekupararira kwakakura munzvimbo iyi, kureba kwekutapurirana kunogumira kusvika pa70 ~ 80km. Kana kutapurirana kure-kure pamwero we10Gbit/s kana pamusoro kuchidikanwa munzvimbo ye1550nm,, muripo wekuparadzira unodiwa. G.652C uye G.652D optical fibers inobva paG.652A uye B zvichienderana. Nekuvandudza maitiro, iyo attenuation munharaunda ye 1350 ~ 1450nm inoderedzwa zvakanyanya, uye iyo wavevelength yekushanda inowedzerwa kusvika 1280 ~ 1625nm. Mabhendi ese aripo akakura pane akajairwa single-modhi fibers. Fiber optics yakawedzera neinopfuura hafu.
G.652D faibha inonzi wavelength range yakatambanudzwa imwe-modhi faibha. Zvimiro zvayo zvakangofanana neG.652B fiber, uye attenuation coefficient yakafanana neG.652C fiber. Kureva, sisitimu inogona kushanda mu1360 ~ 1530nm bhendi, uye iripo yekushanda wavelength range iG .652A, inogona kusangana nezvinodiwa zvekusimudzira zvehukuru-hukuru uye yakakwirira-density wavelength division multiplexing tekinoroji mumetropolitan area network. Iyo inogona kuchengetedza yakakura inogona kushanda bandwidth kune optical network, chengetedza optical tambo yekudyara uye kuderedza mutengo wekuvaka. Uyezve, iyo polarization mode dispersion coefficient yeG.652D fiber yakanyanya kuoma kupfuura iyo yeG.652C fiber, ichiita kuti ive yakakodzera kutenderera kure kure.
Iyo yekushanda essence yeG.656 fiber ichiri isiri-zero dispersion fiber. Kusiyana pakati peG.656 optical fiber uye G.655 optical fiber ndeyokuti (1) ine bandwidth yakawanda yekushanda. Iyo inoshanda bandwidth yeG.655 optical fiber i1530 ~ 1625nm (C+L bhendi), nepo inoshanda bandwidth yeG.656 optical fiber iri 1460 ~ 1625nm (S+C+L bhendi), uye inogona kuwedzerwa kupfuura 1460 ~ 1625nm mune ramangwana, iyo inogona kunyatso tora mukana weiyo hombe bandwidth yequartz girazi fiber; (2) The dispersion slope iduku, iyo inogona kuderedza zvakanyanya kupararira kweDWDM system Kubhadhara mari. G.656 optical fiber is a non-zero dispersion shifted optical fiber ine dispersion slope ye basically zero uye operating wavelength range inovhara S+C+L bhendi rebroadband optical transmission.
Tichifunga nezvekuvandudzwa kweramangwana rehurongwa hwekutaurirana, zvinokurudzirwa kushandisa optical fibers eiyo imwechete subtype mune imwecheteyo system. Kubva pakuenzanisa kwezvikamu zvakawanda zvakadai se chromatic dispersion coefficient, attenuation coefficient, uye PMDQ coefficient, muchikwata cheG.652, PMDQ yeG.652D fiber yakanyanya kunaka kupfuura yezvimwe zvikamu uye ine basa rakanakisisa. Tichifunga nezvezvinhu zvinodhura, G .652D optical fiber ndiyo yakanakisa sarudzo yeOPGW optical cable. Kubata kwakazara kweG.656 optical fiber zvakare kuri nani kupfuura iyo yeC.655 optical fiber. Inokurudzirwa kutsiva G.655 optical fiber neG.656 optical fiber mubasa.
