Qhia Taw Qhia ntawm WDM (Wavelength Division Multiplexing)

Taw qhia ntawm WDM (Wavelength Kev faib tawm ntau yam)

WDM(The Wavelength Division Multiplexing) yog thev naus laus zissivntau lub lasers rau tib lub sijhawm xa cov kab teeb ci ntau ntawm ntau qhov ntev sib txawv.Txhua lub teeb liab kis tau raws li nws cov cim xim tom qab cov ntaub ntawv (cov ntawv nyeem, lub suab, video, thiab lwm yam) tau hloov kho.WDM tuaj yeem ntxiv qhov peev txheej ntawm cov txheej txheem fiber ntau kho kom zoo rau cov tuam txhab xov tooj thiab lwm yamneeg teb xov toojs.Cov neeg tsim khoom muajtaws teebWDM systems, tseem hu ua DWDM (ntom ntwg faib ua ntau seem) cov kab ke.

DWDM tuaj yeem txhawb ntau dua 150 kab teeb ntawm qhov sib txawv ntawm lub yoj yuag tib lub sijhawm, nrog txhua lub nqaj nce mus txog 10Gb / s ntawm cov ntaub ntawv sib kis.Cov txheej txheem muab ntau dua 1Tb / s ntawm cov ntaub ntawv xa mus rau hauv ib txoj kab uas sib txawv dua li cov plaub hau.

Kev sib txuas lus kho qhov muag yog txoj kev xa cov cim los ntawm lub teeb.Hauv thaj teb ntawm kev sib txuas lus kho qhov muag, tib neeg tau siv npetej los ntawmlub wavelength es tsis yoglos ntawmqhov zaus.Yog li, qhov thiaj li hu ua Wave Division Multiplexing (WDM, Wavelength Division Multiplexing) yog qhov tseem ceeb zaus faib ntau zaus.WDM nyob rau 1 lub fiber kho qhov muag nqa ntau lub yoj yob (cov kab) channel,tig1 optical fiber rau hauvzovGG quot; virtual" ficov tom.Of chav kawm, txhua virtualfiber ntauua haujlwmsywj siab rau ntawm nyias wavelengths. It zoo heev txhim kho cov peev xwm kis ntawm optical fiber.Vim tias kev lag luam thiab kev ua tau zoontawm WDM txheej txheem thev naus laus zis, nws dhau los ua lub ntsiab lus ntawm kev nthuav dav tam sim no ntawm cov kab ke sib txuas lus fiber ntau.Asa yam ntawm cov txheej txheem tswvyim, WDM thev naus laus zis feem ntau muaj peb hom Multiplexing txuj, namely 1 310 nm thiab1550 nm Wavelength ntawm WDM, Sib Hloov Wavelength Division Multiplexing (CWDM, Coarse twg Division Multiplexing) thiab Dense Wavelength Division Multiplexing (DWDM, Dense nyob qhov twg Division Multiplexing).

Nta:

(1) ultra-lojmuaj peev xwmkis.

(2) txuag cov khoom siv fiber ntau.

(3) channel pob tshab kis tau tus mob, txhim kho du thiab nthuav dav.

(4) siv EDFA kom ua tiav qhov ntev-deb kis.

(5) txhim kho kev ntseeg tau ntawm qhov system.

(6) txhua qhov khoos phis tawm tag nrho yuav tsim tau.

Qhov zoo:

Qhov zoo dua ntawm DWDM yog tias nws cov raws tu qauv thiab kev thauj mus los tsis sib xws.Networkbased ntawm DWDM tuaj yeem siv tus IP, ATM, SONET / SDH thiab Ethernet raws tu qauv kom xa cov ntaub ntawv, kev ua cov ntaub ntawv ntwsnruab nrab ntawm100 Mb / s thiab 2.5 Gb / s.Yog li, tes hauj lwm raws li DWDM tuaj yeemxasib txawv ntawm cov ntaub ntawv ntawmib tuglaser channel hauv ntau nrawm.Txij ntawm QoS (cov kev pabcuam zoo)saib, DWDM network yogteb tau sailawvrau cov neeg muas zaub' bandwidth xav tau thiab cov kev hloov pauv raws liatus nqi tsawgtxoj kev.Coj 1600G piv txwv: hauv kev tshawb xav, ib qho hlua hluav taws xob fiber ntau tuaj yeem siv 160 10G haujlwm thaum lubfiber ntaucable muaj tag nrho, Kev siv fiber ntau txhim kho zoo heev.Yog lawm, qhov yuav tsum tau ua los ntawm fiber ntau them rau cable yog qhov siab heev, qhov theoretical tus nqi thiab tus nqi tiag tiag yog qhov xwm txheej, hauv kev thov, kom tsis txhob muaj qhov tsis ua tiav,nws yogtsis tshua muajmus ua haujlwmkev lag luam ntawm 100 channel hauv tib lub fiber.

OPTICO (Fiberopticom.com) tsom mus rau kev tsim cov fiber ntau cov khoom lag luam kab thiab muab kev daws teeb meem zoo rau cov khoom siv sib txuas fiber ntau, nrog kev paub hauv daim teb no rau ntau tshaj 18 xyoo. Vim tias peb cov txiaj ntsig zoo thiab kev pabcuam zoo tshaj plaws, peb cov khoom tau muaj kev vam meej mus rau thoob plaws ntiaj teb. Tam sim no peb tabtom muab cov khoom lag luam rau cov haujlwm hauv zos ntawm Tebchaws Europe.

Peb muabWDM (Wavelength Division Muab Ntau Ntau)thiab cov kev daws teeb meem. Thiab, peb muab kev pabcuam kev pabcuam raws li WDM kev tsim qauv. Zoo siab tos ntsoov los tsim kev koom tes ua lag luam ntev nrog koj.
