EDFAyog lub ntsiab lus ntawm lus Askiv "Erbium-doped Optical Fiber Amplifier", uas txhais tau hais tias Erbium-doped Fiber Amplifier,
Nws yog ib qho khoom siv kho qhov muag uas ua kom lub teeb pom kev zoo
Niaj hnub no, kev sib txuas lus kho qhov muag tau nthuav dav thoob plaws ntiaj teb, thiab kev sib txuas lus kho qhov muag fiber ntau tau dhau los ua tus ncej tseem ceeb ntawm "cov ntaub ntawv xov xwm superhighway". Txawm li cas los xij, vim tias qhov kev sib kis tsis zoo ntawm cov fiber ntau optical nws tus kheej, lub teeb liab kho qhov muag tsuas yog kis tau los ntawm kev ncua deb, thiab nws yuav raug txo qis rau qhov uas tus txais tsis tuaj yeem paub qhov txawv. Los ntawm lub hauv ntej optical relay, "optical-hluav taws xob-optical" txoj kev yog siv rau optical amplification. Ib tug kiv puag ncig nyob rau hauv optical kev sib txuas lus technology tshwm sim los ntawm lub advent ntawmEDFAplays lub luag haujlwm tseem ceeb hauv cov tshuab xa ntawv thiab kev sib txuas lus, cable TV thiab khoos phis tawj uas siv cov fibers optical los ua cov xov xwm sib kis.
Nta
Lub module yog ib qho kev sib xyaw erbium-doped fiber ntau amplifier, uas tau muab faib ua ob hom: optoelectronic integrated EDFA module thiab optical nce module. Nws muaj cov yam ntxwv ntawm qhov me me, kev siv hluav taws xob tsawg, thiab siv tau yooj yim. Nws tuaj yeem ntsia tau yooj yim hauv ntau yam xws li cov ntawv thov, xws li SDH khib, CATV lub thawv, DWDM system khib.
qhov zoo
1. Kev ua haujlwm siab: Lub twj tso kua mis ua ntej feem ntau yog 980nm, thiab lub twj tso kua mis tom qab yog 1480nm. Lub hwj chim yog qhov tsim nyog tau txais txiaj ntsig los ntawm software kom txo qis NF ntawm EDFA, uas yog piv rau qhov hu ua low-power optical amplifier. Lub kaw lus tuaj yeem tau txais CNR zoo heev.
2. Kev ntseeg tau: Nws txais 19 "1U standard rack, built-in high-performance switching power supply, muaj peev xwm ua hauj lwm nyob rau hauv 85∽265Vac mains voltage, thiab kuj xaiv DC48V fais fab mov (reservation yuav tsum); chassis tshav kub dissipation tuaj yeem tswj tau los ntawm qhov kub thiab txias.
3. Intuitiveness: Lub twj tso kua mis laser yog cov khoom kim tshaj plaws ntawm tag nrho lub tshuab. Lub tshuab tau nruab nrog lub microprocessor los saib xyuas lub xeev ua haujlwm ntawm lub twj tso kua mis laser, thiab qhov ua haujlwm tsis ua haujlwm tau tshwm sim los ntawm lub vaj huam sib luag LCD qhov rai.
Muaj nuj nqi
1. Network tswj hom: Cov kev xaiv raws li txoj cai saib xyuas transponder yog lav kom ua tau raws li lub teb chaws tus qauv thiab tau sib xws nrog SCTE HMS tus qauv, uas tuaj yeem paub txog kev tswj xyuas kev tswj xyuas network.
2. Fais fab plug-nyob rau hauv hom: plug-in hom switching fais fab mov adopts txhuas profile qauv, uas yog conducive rau tshav kub dissipation thiab hloov. Thiab dual lub zog kub thiab txias thaub qab.
3. Adjustable output optical power: adjustable range of output optical power (-3dB), cov neeg siv yuav tsum qhia kom meej thaum xaj.
