Dab tsi yog fiber ntau optical siv rau kev sib txuas lus network?
Muaj peb hom tseem ceeb: G.652 pa ib hom fiber ntau, G.653 dispersion-hloov ib hom fiber ntau ibd G.655 non-zero dispersion-hloov fiber ntau.
G.652 ib hom fiber ntaumuaj qhov sib txawv loj hauv C-band 1530 ~ 1565nm thiab L-band 1565 ~ 1625nm, feem ntau 17 ~ 22psnm•km, thaum lub kaw lus tus nqi nce mus txog 2.5Gbit / s lossis ntau dua, kev them nyiaj dispersion yog xav tau, ntawm 10Gbit / s Dispersion them nyiaj tus nqi ntawm cov kab ke yog qhov siab, thiab nws yog hom fiber ntau tso rau hauv kev sib kis network tam sim no.
Lub dispersion ntawmG.653 dispersion-hloov fiber ntaunyob rau hauv C-band thiab L-band feem ntau yog -1 ~ 3.5psnm•km, nrog xoom dispersion ntawm 1550nm, thiab qhov system tus nqi tuaj yeem ncav cuag 20Gbit / s thiab 40Gbit / s, uas yog ib leeg-yoj ultra-ntev-ntev. kis tau tus mob Qhov zoo tshaj plaws fiber.Txawm li cas los xij, vim nws qhov tsis muaj qhov tsis sib xws, thaum DWDM siv rau kev nthuav dav, cov teebmeem tsis zoo yuav tshwm sim, ua rau lub teeb liab crosstalk, ua rau plaub-yoj sib xyaw FWM, yog li DWDM tsis haum.
G.655 non-zero dispersion-hloov fiber ntau: G.655 non-zero dispersion-hloov fiber ntau muaj qhov tawg ntawm 1 txog 6 psnm•km hauv C-band, thiab feem ntau 6-10 psnm•km hauv L-band.Lub dispersion yog me me thiab tsis txhob xoom.Lub cheeb tsam dispersion tsis tsuas yog suppresses plaub-yoj sib xyaw FWM, tuaj yeem siv rau DWDM nthuav dav, tab sis kuj tuaj yeem qhib cov tshuab ceev ceev.Tus tshiab G.655 fiber ntau tuaj yeem nthuav dav thaj chaw zoo rau 1.5 mus rau 2 npaug ntawm cov fiber ntau zoo tib yam, thiab thaj chaw ua haujlwm loj tuaj yeem txo lub zog ceev!
