Ib qho chaw nres nkoj EDFA
Peb module lub teeb pumped laser thiab Erbium-Doped Fiber yog siv los ntawm cov khoom qub los ntawm Tebchaws Meskas.
Peb muaj txhim khu kev qha kho qhov muag lub teeb lub zog tso zis stabilizing Circuit Court thiab laser hluav taws xob tub yees kub los tswj lub Circuit Court, lav lub tshuab ua kom tiav kev ua tau zoo thiab lub laser ntev lub neej ruaj khov ua haujlwm..
Lub microprocessor software muaj laser saib xyuas, cov zaub tsis raug ceeb toom, network tswj thiab ntau yam haujlwm.Thaum lub laser lub lag luam parameter deviate software tsim kev tso cai, nws yuav kaw laser lub hwj chim txiav.Lub teeb liab coruscate, lub tswb nrov thiab cov ntsiav tshuaj digitizing yuav taw qhia qhov ua txhaum.
Lub microprocessor software muab RS-232 thiab 485 interface siv rau kev tswj xyuas network thiab kev saib xyuas tej thaj chaw deb.
Peb txais yuav 1RU 19 "tus qauv cav ncej npaum li cas hloov lub zog, 90-265V hluav taws xob hluav taws xob.
Cov yam ntxwv ua haujlwm Kev xaiv ntawm thoob ntiaj teb nto moo hom ntawm lub suab nrov twj tso kua mis laser, tsis tshua muaj distortion, dav band, siab tso zis lub teeb zog Adopts imported high-performance baits fiber ntau, siab zog conversion efficiency. Lub zog thiab cov twj tso kua mis lasers ntawm txhua yam kev ua haujlwm raws li txoj cai, ua kom lub zog kho qhov muag ruaj khov, thiab ua kom ntev lub neej ua haujlwm ntawm lub twj tso kua mis laser. Pem hauv ntej vaj huam sib luag nyob rau hauv-kab xiav tshuaj ntsuam 160 * 32 dot-matrix LCD zaub, displaying precisely cov xwm txheej ntawm cov khoom tsis. 19 "rack 1U tus qauv siab, nruab nrog cov qauv Ethernet interfaces IEEE802.310Base-T thiab RS-232 interfaces, tuaj yeem pab txhawb kev paub txog kev saib xyuas network. Kev them nyiaj yug tag nrho rau 《GB/T 20030-2005 kev tswj hwm ntawm HFC network khoom specifications》
