G.657A1 Ukugoba-ifiber yemowudi enye

G.657A1 Ukugoba-imowudi enye ifayibha ebonakalayo Umfanekiso

Inkcazelo emfutshane:

Imveliso ithatha ubuchwephesha bokwenza intonga yokwenziwa kwangaphambili, obunokulawula umxholo we-OH wentonga eyenziweyo ukuya kwinqanaba eliphantsi kakhulu, ngoko ke imveliso inencopho egqwesileyo yokuthomalalisa kunye nencopho yamanzi ephantsi, ukusebenza okugqwesileyo kokuhanjiswa. Imveliso inokuqinisekisa i-radius encinci yokugoba ngelixa ihambelana ngokupheleleyo nenethiwekhi ye-G.652D, ngoko i-fiber inokuhlangabezana ngokupheleleyo neemfuno zocingo ze-FTTH.

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. Ukusetyenziswa kwe-fiber optics kubandakanya: iinkqubo ze-fiber optic ezifuna ilahleko ephantsi kunye ne-bandwidth ephezulu; Ilungele ngokukodwa i-MAN intambo ye-soft optical, i-package encinci ye-fiber device, i-optical fiber coupler kunye nezinye izicelo ezikhethekileyo;

3. Olu hlobo lwefiber lufanelekile kwiibhendi ze-O, E, S, C kunye ne-L (oko kukuthi, ukusuka kwi-1260 ukuya kwi-1625nm). Olu hlobo lwefiber optical luhambelana ngokupheleleyo ne-G.652D fiber. Iinkcukacha zokulahleka kokugoba kunye nendawo edibeneyo ziphuculwe kakhulu, zombini ukuphucula uqhagamshelwano;

4. Inokuxhasa ukufakwa kwe-half-diameter encinci kunye ne-volume encinci ye-fiber optical processing systems kwii-telecommunication office stations kunye neendawo zabathengi kwizakhiwo zokuhlala kunye neendawo zokuhlala.
