Idivayisi Yesinxephezelo Sokuhlakazeka kwe-DCM
Umsebenzi wokunxeshezelwa kwe-Huanet obonakalayo onesinxephezelo sokuhlakazeka kwemithambeka ku-fiber ejwayelekile yemodi eyodwa i-DCM (G.652) bekuyibhande elibanzi lesinxephezelo se-slope sokuhlakazeka nebhendi ku-C-band, okuvumela isistimu ukuthi ilungiselele ukuhlakazwa kwensalela.Ngenani lesinxephezelo sokuhlakazwa kwe-1545nm wavelength dispersion ingafinyelela -2070ps / nm.
I-DCM inikezela ngezinga eliphezulu lesinxephezelo sokuhlakazwa kanye nesijeziso sokulahlekelwa esiphansi kakhulu sokufaka.Banikeza isinxephezelo esibi sokuhlakazeka phezu kwe-C-Band egcwele enezandiso zebanga ezingafika kumakhilomitha angu-120. Umsebenzi Isinxephezelo sokuhlakazwa kwesistimu ye-DWDM kanye nokuhlakazeka okuphansi kwensalela ye-broadband Isinxephezelo Sokuhlakazwa kanye Nesinxephezelo Seslope Sokuhlakazeka Kutholwe ngesinxephezelo esithile sokuhlakazwa kwe-wavelength, kufanele kwanelise ubudlelwano obulandelayo: I-DTF × LTF + DDCF × LDCF = 0 I-DTF: ukuhlakazeka kwefayibha yokudlulisela; I-LTF: ubude befayibha yokudlulisela; I-DDCF: ukuhlakazwa kokuhlakazeka kunxephezela i-fiber optical; I-LDCF: ubude befayibha yesinxephezelo sokuhlakazwa; Isinxephezelo semithambeka yokusabalalisa ebhendini, kufanele senelise ubudlelwano obulandelayo: STF × LTF + SDCF × LDCF = 0 I-STF: ukuhlakazwa kwefayibha yokudlulisela; I-SDCF: ukuhlakazwa kokuhlakazeka kunxephezela i-fiber optical Ngokwalobu budlelwano obubili obungenhla bathola isinxephezelo sokuhlakazwa kanye nokwehla kokuhlakazeka isinxephezelo, kufanele kwenelise ubudlelwano obulandelayo: RDSDCF = SDCF / DDCF = STF / DTF Kucatshangwa ukuthi i-fiber yemodi eyodwa ejwayelekile ku-1545nm wavelength dispersion ye-16.7ps / nm / km, i-dispersion slope engu-0.060 ps / nm2 / km, RDS cishe 0.0036nm﹣1.
