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 ihlinzeka 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
I-G.652 fiber C-band 100% isinxephezelo seslope (inani elijwayelekile)
Ukulahlekelwa kokufaka okuphansi
Ukuhlakazwa kwemodi ye-polarization ephansi
Izinkomba zokusebenza ngesitifiketi esijwayelekile se-Telcordia GR-2854-CORE
Ukuthembeka ngesitifiketi esijwayelekile se-Telcordia GR-1221-CORE

 

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:

I-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 0.0036nm1.
