Kev ua haujlwm siab lub tshuab ua kom laser, lub suab qis erbium-doped fiber ntau thiab lub cim kev tiv thaiv thiab kev tiv thaiv ib puag ncig yog siv hauv EDFA kom paub txog lub suab qis thiab siab ruaj khov tsim tawm. Lub vaj huam sib luag pem hauv ntej muab lub hwj huam hloov, LCD tso saib hluav taws xob, tso zis hluav taws xob hloov kho pob qhov rooj, thiab RS232 interface. Nws yog dav siv nyob rau hauv optical fiber sensing thiab optical fiber sib txuas lus tshuab ua piv txwv ua ntej.
Kev faib tawm ntawm EDFA
1. Lub zog txuas ntxiv, nyob tom qab ntawm kev sib txuas, yog siv los txhim kho lub zog ntawm ntau lub suab yoj tom qab sib txuas, thiab tom qab ntawd hloov lawv. Txij li lub teeb liab lub zog tom qab kev sib txuas ua ke feem ntau loj, qhov yuav tsum tau ua rau lub suab nrov thiab nce ntawm lub zog txuas ntxiv tsis loj heev, tab sis nws yuav tsum muaj lub zog loj tsim tawm tom qab ua kom nrov zog.
2. Cov kab txuas ntxiv, tom qab cov tshuab fais fab txuas, raug siv qee lub sijhawm los tiv thaiv qhov kis poob ntawm cov kab. Feem ntau, nws yuav tsum muaj suab nrov qis qis dua thiab cov zis hluav taws xob ntau dua.
3. Ua ntej amplifier siv rau cov teeb meem ua ntej ua ntej nthwv dej splitter thiab tom qab cov kab amplifier kom txhim kho qhov rhiab heev ntawm tus txais (thaum OSNR ua tau raws li qhov yuav tsum tau, lub zog loj dua tuaj yeem txwv lub suab nrov ntawm tus txais nws tus kheej thiab txhim kho lub teeb tsa kom zoo). Lub suab nrov yuav tsum tau me me, thiab lub zog tsim tawm tsis tas yuav ntau dhau lawm.

Cov kev ceev faj rau kev saib xyuas ntawm cov khoom siv sib txuas
Kev ua kom huv ntawm cov kho qhov muag txuas yog ib qho khoom tseem ceeb hauv kev saib xyuas ntawm cov kho qhov muag kom nrov dua. Txhawm rau kom muaj kev nyab xeeb thiab ua kom huv, thov ua raws li txoj cai hauv qab no:
● Ntxuav lub fiber kawg lub ntsej muag nrog lub cawv thiab nqus cov paj rwb lossis lwm cov ntaub so so tshwj xeeb
Muab tsau rau hauv cov cawv tsis zoo thiab maj mam chwv lub ntsej muag kawg ntawm tus txuas rau txhaws tawm cov hmoov av thiab lwm qhov tsis zoo ntawm lub ntsej muag kawg.
Don' t siv siv dag zog los so rov qab thiab ntxiv rau sab kawg ntsej muag ntawm cov khoom siv kho qhov muag kom tsis txhob khawb lub ntsej muag kawg
● Don' t huv si thaum lub txuas tseem muaj lub teeb tawm, kom tsis txhob muaj kev puas tsuaj lub ntsej muag kawg
C-band 40ch DWDM EDFA erbium doped optical preamplifier
DWDM EDFA yog lub suab qis, nce tiaj tus C-band erbium-doped optical zog amplifier tsim kom nthuav dav ntom nti hluav taws xob faib ua ntau yam sib luag (DWDM).
Qhov kev sib kis deb ntawm optical theem pib DWDM EDFA fiber ntau lub zog muaj qhov ua tau zoo, uas tuaj yeem nthuav tawm 100GHz, 40 channel, 2.5Gbps lossis 10Gbps optical basic network.
Tam sim no, fiber ntau lub tshuab hluav taws xob tau siv dav hauv DWDM xa cov kab ke, kho qhov muag fiber CATV thiab kho qhov muag txuas network.
DWDM cov tshuab ua haujlwm feem ntau yog los ntawm kev ua ob sab xov tooj hluav taws xob xa mus, tab sis tus kis tshwj xeeb tshaj tawm txoj kev tsuas yog ib seem xwb.
Qhov tshwj xeeb tshaj tawm tau muab tso rau ntawm qhov chaw txais hluav taws xob kom them cov nqi tsis poob ntawm cov multiplexer ze rau cov chaw txais hluav taws xob los ntawm kev kho qhov muag.
HTF kuj kho kom haum OTN cov kev daws teeb meem rau cov neeg siv khoom kom yooj yim dua thiab yoog raws.
Yog tias koj xav tau dab tsi, koj tuaj yeem hu rau HTF Zoey.
