G.652D I-Optical fiber yemodi enye (B1.3)-iBanga B

G.652D Imowudi enye yefiber optical (B1.3)-iBakala B Umfanekiso obonakalayo

Inkcazelo emfutshane:

Incopho yamanzi asezantsi non-dispersive displacement ifayibha enye-mode ilungele inkqubo yothumelo yebhendi epheleleyo 1280nm ~ 1625nm, engagcini nje ukusasazwa okuphantsi kwebhendi yemveli 1310nm, kodwa inelahleko ephantsi kwi-1383nm, yenza i-E band. (1360nm ~ 1460nm) isetyenziswe ngokupheleleyo.Ilahleko kunye nokusabalalisa kwebhendi yonke ukusuka kwi-1260nm ukuya kwi-1625nm iphuculwe, kwaye ukulahlekelwa kwe-bending ye-1625nm ye-wavelength iyancitshiswa, ebonelela ngezibonelelo ze-bandwidth ye-backbone network, i-MAN kunye nokufikelela kwinethiwekhi.

Iimpawu zeMveliso

● Isalathiso se-fiber ye-fiber ye-fiber ye-mode-mode enye ye-low-dispersion-shifted ingcono kune-ITU-T ecetyiswayo ye-G.652D kunye ne-IEC B1.3 ye-fiber zobuchwepheshe zobugcisa;

● Ukusebenza okugqwesileyo kwamehlo, kunokwanelisa ukusebenza kakuhle okuphezulu kwe-DWDM kunye nokuhanjiswa kweemfuno zenkqubo yeCWDM;

● Ubungakanani bejometri obugqwesileyo, ukuqinisekisa ukudityaniswa kwelahleko ephantsi kunye nokusebenza kokutywinwa okuphezulu;

● I-coefficient ephantsi ye-PMD, iyanelisa inkqubo yokudluliselwa komgama omde kunye nokusebenza okuphezulu.

Ukuveliswa kweMveliso

Isicelo seMveliso

1. Ilungele zonke iintlobo zesakhiwo se-fiber optic cable: uhlobo lwe-tube ye-beam ephakathi, i-sleeve ye-sleeve layer stranded type, uhlobo lwamathambo, i-fiber optic cable structure;

2. Izicelo ze-fiber optical zibandakanya: iinkqubo ze-fiber optical ezifuna ilahleko ephantsi kunye ne-bandwidth ephezulu, njengonxibelelwano olude olude, imigca ye-trunk, i-loop feeders, imigca yokusabalalisa kunye ne-cable TV, njl., ngokukodwa ifanelekile kwi-1383nm band coarse wavelength division multiplexing ( I-CWDM), i-multiplexing ye-wavelength division multiplexing (i-DWDM) kunye nokusetyenziswa okukhethekileyo kokusingqongileyo (umz. Ubungqina bombane we-OPGW optical cable, i-ADSS optical cable, njl. inomsebenzi ophezulu ngakumbi kwiipropati zomatshini kunye nokusebenza kobushushu obuphezulu bendalo.
