Mitundu ya fiber amplifiers

Pamene mtunda wotumizira uli wautali kwambiri (kupitirira 100 km), chizindikiro cha kuwala chidzakhala ndi kutaya kwakukulu.M'mbuyomu, anthu nthawi zambiri ankagwiritsa ntchito makina obwereza kuti akweze chizindikiro cha kuwala.Zida zamtunduwu zili ndi malire pakugwiritsa ntchito.M'malo mwa optical fiber amplifier.Mfundo yogwirira ntchito ya optical fiber amplifier ikuwonetsedwa pachithunzichi.Ikhoza kukulitsa mwachindunji chizindikiro cha kuwala popanda kudutsa njira yosinthira optical-electrical-optical conversion.

 Kodi fiber amplifier imagwira ntchito bwanji?

Ndi mitundu yanji ya fiber amplifiers yomwe ilipo?

1. Erbium-doped fiber amplifier (EDFA)

Erbium-doped fiber amplifier (EDFA) imapangidwa makamaka ndi erbium-doped CHIKWANGWANI, gwero la kuwala kwa pampu, optical coupler, optical isolator, ndi optical filter.Pakati pawo, erbium-doped fiber ndi gawo lofunikira kwambiri pakukulitsa chizindikiro cha kuwala, chomwe chimagwiritsidwa ntchito makamaka kukwaniritsa 1550 nm Band optical signal amplifier, motero, erbium-doped fiber amplifier (EDFA) imagwira ntchito bwino mu kutalika kwa 1530 nm mpaka 1565 nm.

Aubwino:

Kugwiritsa ntchito mphamvu kwambiri pampu (kuposa 50%)

Ikhoza mwachindunji komanso nthawi imodzi kukulitsa chizindikiro cha kuwala mu gulu la 1550 nm

Kupeza kuposa 50 dB

Phokoso lochepa pamapazi akutali

chopereŵera

Erbium-doped fiber amplifier (EDFA) ndi yayikulu

Zidazi sizingagwire ntchito mogwirizana ndi zida zina za semiconductor

2. Raman amplifier

Raman amplifier ndi chipangizo chokhacho chomwe chimatha kukulitsa ma siginecha amtundu wa 1292 nm ~ 1660 nm.Mfundo yake yogwirira ntchito imachokera ku mphamvu ya Raman yobalalika mu ulusi wa quartz.Monga momwe tawonetsera m'chithunzichi, pamene kuwala kwapampu kumakokedwa Pamene chizindikiro chofooka chochepa mu Mann chikupeza bandwidth ndi mphamvu yamagetsi yamagetsi yamagetsi imaperekedwa panthawi imodzimodziyo mu fiber optical, chizindikiro chofooka cha kuwala chidzakulitsidwa chifukwa cha kufalikira kwa Raman. .

Aubwino:

Mitundu yosiyanasiyana yamagulu omwe amagwiritsidwa ntchito

Itha kugwiritsidwa ntchito poyika ma single-mode fiber cabling application

Itha kuwonjezera zofooka za erbium-doped fiber amplifier (EDFA)

Kugwiritsa ntchito mphamvu zochepa, kutsika kwapang'onopang'ono

Mphamvu yapampu yapamwamba

3. Semiconductor optical fiber amplifier (SOA)

Semiconductor optical fiber amplifiers (SOA) amagwiritsa ntchito zipangizo za semiconductor monga kupeza media, ndipo mawonekedwe awo opangira mawonekedwe ndi zotulutsa zimakhala ndi zokutira zotsutsa-reflection kuti zisawonongeke kumapeto kwa nkhope ya amplifier ndi kuthetsa zotsatira za resonator.

Aubwino:

voliyumu yaying'ono

Mphamvu zochepa zotulutsa

Kupeza bandwidth ndi kochepa, koma kumatha kugwiritsidwa ntchito m'magulu osiyanasiyana

Ndizotsika mtengo kuposa erbium-doped fiber amplifier (EDFA) ndipo zitha kugwiritsidwa ntchito ndi zida za semiconductor.

Ntchito zinayi zopanda mzere zosinthira kupindula, kusinthasintha kwa magawo, kutembenuka kwa mafunde ndi kusakanikirana kwa mafunde anayi zitha kuchitika.
