Mitundu yama fiber amplifiers

Pamene mtunda wotumizira uli wautali kwambiri (wopitilira 100 km), chizindikirocho chimawonongeka kwambiri. M'mbuyomu, anthu nthawi zambiri amagwiritsa ntchito makina obwereza kuti akweze chizindikiro. Zida zamtunduwu zimakhala ndi malire pazomwe zingagwiritsidwe ntchito. M'malo ndi kuwala CHIKWANGWANI mkuzamawu. Mfundo yogwirira ntchito yama fiber fiber amplifier ikuwonetsedwa pachithunzipa. Itha kukulitsa mwachindunji chizindikirocho popanda kusintha njira yamagetsi yamagetsi.

 Kodi mkuzamawu umagwira bwanji?

Pamene mtunda wotumizira uli wautali kwambiri (wopitilira 100 km), chizindikirocho chimawonongeka kwambiri. M'mbuyomu, anthu nthawi zambiri amagwiritsa ntchito makina obwereza kuti akweze chizindikiro. Zida zamtunduwu zimakhala ndi malire pazomwe zingagwiritsidwe ntchito. M'malo ndi kuwala CHIKWANGWANI mkuzamawu. Mfundo yogwirira ntchito yama fiber fiber amplifier ikuwonetsedwa pachithunzipa. Itha kukulitsa mwachindunji chizindikirocho popanda kusintha njira yamagetsi yamagetsi.

Kodi ndi mitundu iti yama amplifiers omwe amapezeka?

1. Erbium-doped fiber amplifier (EDFA)

Erbium-doped fiber amplifier (EDFA) imapangidwa ndi fiber ya erbium-doped, gwero lowunikira, chophatikizira chamagetsi, chopatula, ndi sefa. Mwa iwo, erbium-doped fiber ndi gawo lofunikira pakukulitsa kwa ma signal, komwe kumagwiritsidwa ntchito kukwaniritsa 1550 nm Band optical signal amplification, chifukwa chake, erbium-doped fiber amplifier (EDFA) imagwira bwino ntchito kutalika kwa 1530 nm mpaka 1565 nm.

Aubwino:

Kugwiritsa ntchito mphamvu yama pampu kwambiri (kuposa 50%)

Itha kulumikiza molunjika komanso nthawi imodzi chikwangwani chowonekera mu 1550 nm band

Pezani zoposa 50 dB

Phokoso locheperako pamafayilo akutali

kulephera

Erbium-doped fiber amplifier (EDFA) ndi yayikulu

Zipangizozi sizingagwire ntchito molumikizana ndi zida zina zama semiconductor

2. Raman zokuzira

Amplifier ya Raman ndi chida chokhacho chomwe chitha kukulitsa mawonekedwe owonekera mu 1292 nm ~ 1660 nm band. Mfundo zake zogwirira ntchito zimadalira momwe Raman amafalitsira mu fiber ya quartz. Monga momwe tawonetsera pachithunzipa, pamene kuwala kwa mpope kumakokedwa Pamene chizindikiro chofooka mu Mann chimapeza bandiwifi ndi mphamvu yamphamvu yamagetsi yamapampu imafalitsidwamo munthawi yomweyo fiber yolowera, chizindikiro chofooka cha kuwala chidzakwezedwa chifukwa cha kufalikira kwa Raman .

Aubwino:

Magulu osiyanasiyana ogwira ntchito

Itha kugwiritsidwa ntchito kuyika njira imodzi yolumikizira fiber

Ikhoza kuwonjezera zoperewera za erbium-doped fiber amplifier (EDFA)

Kugwiritsa ntchito mphamvu zochepa, crosstalk yotsika

cholephera:

Mkulu mpope mphamvu

Zovuta kupeza dongosolo lowongolera

Phokoso

3. Semiconductor fiber fiber amplifier (SOA)

Semiconductor Optical fiber amplifiers (SOA) amagwiritsa ntchito zida zama semiconductor ngati phindu pa media, ndipo mawonekedwe awo opangira ndi zotulutsa zimakhala ndi zokutira zotsutsana kuti zisawonongeke kumapeto kwa zokulitsa ndikuchotsa zomwe resonator imachita.

Aubwino:

voliyumu yaying'ono

Mphamvu yotsika pang'ono

Bandwidth yopindula ndiyochepa, koma itha kugwiritsidwa ntchito m'magulu osiyanasiyana

Ndiotsika mtengo kuposa erbium-doped fiber amplifier (EDFA) ndipo itha kugwiritsidwa ntchito ndi zida zama semiconductor

Ntchito zinayi zosasunthika zofananira pamtanda, kusinthasintha kwapakati, kusintha kwa mawonekedwe a wavelength ndi kusakanikirana kwa mafunde anayi kumakwaniritsidwa

cholephera:

Magwiridwe antchito samakhala okwera ngati erbium-doped fiber amplifier (EDFA)

Phokoso lalikulu komanso phindu lochepa
