DWDM tunableoptical transceiver yog qhov tshwj xeeb optical qauv, uas tuaj yeem xaiv cov channel lossis" xim" ntawm laser emission. Feem ntau lub tshuab DWDM feem ntau siv cov kho qhov muag sib txawv nrog cov nthwv hloov pauv, tab sis cov kho qhov muag tau kho tau muaj peev xwm kho qhov yoj yoj ntawm cov kho qhov muag kom tau raws li qhov thov sib txawv. Nws yuav tsum raug sau tseg tias kev ua qhov hloov wavelength ntawm DWDM tunable optical module tsuas yog siv rau hauv DWDM system.
Cov hom DWDM kho qhov muag tau kho
1. TunableXFP optical module
Lub tunable XFP optical module muaj qhov sib xyaw ua ke C-band tunable transmitter thiab lub siab ua haujlwm.
Lub yoj yoj yoj tuaj yeem tsim los ua qhov tseem ceeb ntawm tus nqi ntawm 50GH DWDM ITU daim phiaj. Qhov chaw siab tshaj plaws ntawm tus kho qhov muag hluav taws xob tuaj yeem ncav cuag 80km rau ib hom fiber ntau. Cov. Hauv kev ua lag luam, txawv cov tuam ntxhab yuav lub npe tunableXFP optical modules ua ntau hom.
2. Tunable SFP + cov khoom siv kho qhov muag
Lub tunable SFP + optical transceiver tuaj yeem muab cov kev kub ceev ntawm qhov txuas los ntawm 9.95Gbps txog 11.3Gbps. Qhov ntsuas hluav taws xob tau txhawb qhov kev txhim kho SFP + tshwj xeeb.
Ntawm kev xa mus los, cov ntaub ntawv serial yog dhau ntawm lub tshuab hluav taws xob txuas mus rau tus tsav tsheb modulator. Tus neeg hloov kho cov qauv hloov kho C-band txias kho cov hloov pauv, thiab paub tseeb cov ntaub ntawv xa mus txog 80km ntawm tib hom fiber ntau los ntawm kev lag luam tus qauv LC txuas. Ntawm qhov tau txais sab, 10G cov ntaub ntawv kho qhov muag tau xa rov qab los ntawm APD mus rau lub tshuab hluav taws xob txuas los ntawm cov khoom hluav taws xob transimpedance amplifier.
