Ib qho chaw nres nkoj EDFA
Peb lub module teeb pumped laser thiab Erbium-Doped Fiber yog siv los ntawm cov khoom siv khi thawj los ntawm Tebchaws Meskas.
Peb muaj lub zog tso zis teeb pom kev zoo txhim khu kev qha thiab lub tub yees hluav taws xob laser kom tswj tau lub voj voog, lav qhov ua tiav ntawm lub tshuab ua haujlwm zoo tshaj plaws thiab lub neej ntev ntawm laser ua haujlwm ruaj khov ..
Cov software microprocessor muaj cov saib xyuas laser, cov lus ceeb toom txog qhov yuam kev digital, kev tswj hwm network thiab ntau yam haujlwm. Thaum lub laser ua haujlwm tsis zoo, software tsim kom muaj qhov kev tso cai, nws yuav kaw lub zog laser cia. Lub teeb liab ci ntsa iab, ceeb toom sai sai thiab lub ntsiav tshuaj digital yuav taw qhia qhov ua rau muaj qhov yuam kev.
Cov software microprocessor muab RS-232 thiab 485 interface siv rau kev tswj hwm network thiab kev saib xyuas chaw taws teeb.
Peb txais yuav 1RU 19 "tus qauv cav ncej txuag hluav taws xob, 90-265V hluav taws xob.
Cov yam ntxwv ntawm kev ua tau zoo Kev xaiv ntawm lub npe nrov thoob ntiaj teb ntawm cov twj tso kua mis qis qis, tsis muaj kev cuam tshuam, dav band, lub zog tso zis siab Txais yuav cov khoom siv fiber ntau uas xa tawm los ntawm txawv teb chaws, ua kom muaj zog hloov pauv tau zoo. Lub zog thiab pumped lasers ntawm txhua yam kev ua haujlwm, kom ntseeg tau tias muaj lub zog tso zis optical ruaj khov, thiab ua kom lub neej ua haujlwm ntawm lub twj tso kua mis laser ntev dua. Lub vaj huam sib luag pem hauv ntej hauv kab xiav npo 160 * 32 dot-matrix LCD zaub, qhia meej txog qhov xwm txheej ntawm cov khoom siv. 19 "khib 1U tus qauv siab, nruab nrog cov qauv Ethernet interfaces IEEE802.310Base-T thiab RS-232 interfaces, tuaj yeem pab txhawb kev ua tiav ntawm lub network monitor. Kev txhawb nqa tag nrho rau "GB/T 20030-2005 kev tswj hwm ntawm HFC network khoom siv specifications"
