Tsanangudzo: Erbium-doped fiber AmplifierEDFA Optical Amplifier

Erbium-doped optical fiber amplifier (EDFA, ndiko kuti, iyo optical signal amplifier neEr3 + doped mu fiber core kuburikidza nechiratidzo) ndiyo yekutanga optical amplifier yakagadzirwa neYunivhesiti yeSouthampton muna 1985, uye ndiyo imwe yezvakanyanya kugadzirwa mu optical fiber communication. Erbium-doped fiber imhando yefayibha ine shoma shoma shoma yepasi element erbium (Er) ions mu quartz fiber, inova musimboti we.Erbium-doped fiber amplifier. Kubva mukupera kwema1980, mabhindauko makuru akaitwa mukutsvagisa kweerbium-doped fiber amplifiers. WDM tekinoroji yakawedzera zvakanyanya kugona kwe optical fiber kutaurirana. Ndiyo inonyanya kushandiswa optical amplifier mune optical fiber kutaurirana.

Chishandiso: Optical fiber amplifier ndeye optical amplifier mudziyo unosimudza zvakananga chiratidzo chemaziso mune optical fiber kutaurirana system. Muchirongwa chekutaurirana uchishandisa optical fiber, inyanzvi inosimudzira zvakananga chiratidzo chemaziso pasina kushandura chiratidzo chemagetsi kuita chiratidzo chemagetsi. Erbium-doped fiber amplifier (EDFA Optical Amplifier, kureva, iyo optical signal amplifier ine erbium ion Er3 + mu fiber core kuburikidza nechiratidzo) ndiyo yekutanga optical amplifier yakagadzirwa neYunivhesiti yeSouthampton muUnited Kingdom uye Japan's Tohoku University, ndiyo imwe yezvakanyanya kugadzirwa mu optical fiber kutaurirana. Erbium-doped fiber imhando yefaibha ine shoma shoma yepasi element element erbium (Er) ions muquartz fiber, inova musimboti weErbium-doped fiber amplifier. Kubva mukupera kwema1980, mabhindauko makuru akaitwa mukutsvagisa kweerbium-doped fiber amplifiers. WDM tekinoroji yakawedzera zvakanyanya kugona kwe optical fiber kutaurirana. Ndiyo inonyanya kushandiswa optical amplifier mune optical fiber kutaurirana.

Basic parameter

Zita rezita: Erbium-doped fiber amplifier

Izwi rinoenderana:Optical Amplifier

Quartz fiber doped ine zvisingawanzo pasi zvinhu (zvakadai seNd, Er, Pr, Tm, nezvimwewo) inogona kuumba multi-level laser system, uye yakananga kukudza chiedza chekuisa chiratidzo pasi pekuita kwechiedza chepombi. Mushure mekupa mhinduro yakakodzera, iyo fiber laser inoumbwa. Iyo yekushanda wavelength yeND-doped fiber amplifier ndeye 1060nm uye 1330nm, asi kukura kwayo uye kushandisa kwayo kunogumira nekuda kwekutsauka kubva kune yakakwana chiteshi chekutaurirana kwefiber uye zvimwe zvikonzero. Iwo ekushanda wavelengths eEDFA nePDFA ari mukurasikirwa kwakaderera (1550nm) uye zero dispersion wavelength (1300nm) hwindo re optical fiber communication zvichiteerana, uye TDFA inoshanda muS-bhendi, iyo yakanyatsokodzera optical fiber communication system application. Kunyanya EDFA, iyo inokurumidza kukura, yave inoshanda.

Pahwaro hwekuvandudzwa kweerbium-doped fiber, akawanda mafiber amplifiers anoramba achionekwa. Semuenzaniso, iyo dual-band fiber amplifier (DBFA) yakavakirwa paerbium-doped fiber ndeye Broadband Optical amplifier, uye Broadband inogona kuvhara inenge yese wavelength division multiplexing (WDM) bandwidth. Chigadzirwa chakafanana ndeye Ultra-wideband Optical amplifier (UWOA), iyo ine yekuvhara bandwidth yekukwidziridza inosvika zana wavelength chiteshi mune imwechete fiber.

Kushanda kunoshanda

Iko kushandiswa kweErbium-doped fiber amplifier (EDFA Amplifier) ​​mune yakajairwa optical fiber dhijitari yekutaurirana system inogona kuchengetedza yakawanda yeOptical Repeaters, uye kureba kureba kwakawedzera zvakanyanya, izvo zvakakosha zvikuru kune refu-kure tambo tambo system.

Zvishandiso zvayo zvikuru zvinosanganisira:

1, inogona kushandiswa sechiedza chinhambwe amplifier. Traditional electronic fiber optic Repeaters vane zvakawanda zvinogumira. Semuenzaniso, kana chiratidzo chedhijitari uye chiratidzo cheanalogi chichishandurwa kune mumwe nemumwe, iyo inodzokorora inofanira kuchinjwa zvinoenderana; Kana iyo midziyo ichichinja kubva yakaderera kumhanya kusvika yakakwira kumhanya, iyo inodzokorora inofanira kutsiviwa zvinoenderana. Chengetedza iwo wavelength yakafanana yechiratidzo chechiedza, uye chimiro chakaoma, chinodhura, zvichingodaro. Erbium-doped fiber amplifiers inokunda kukanganisa uku, kwete chete iyo haifanire kuchinja nekuchinja kwechiratidzo modhi, asi zvakare haidi kutsiviwa kana iyo midziyo yawedzerwa kana kushandiswa kune optical wavelength division multiplexing.

2, inogona kushandiswa seOptical transmitter post amplifier uye optical receiver preamplifier. Seye post amplifier yeiyo optical transmitter, simba rekufambisa relaser rinogona kuwedzerwa kubva pa0db kusvika +10db. Kana ichishandiswa se preamplifier yeoptical receiver, kunzwa kwayo kunogonawo kuvandudzwa zvakanyanya. Naizvozvo, chete 1-2 erbium-doped amplifiers yakaiswa pamutsara, uye chiratidzo chekufambisa chinhambwe chinogona kuwedzerwa ne100-200km.

Mukuwedzera, erbium-doped fiber amplifier (EDFA Amplifier) kugadzirisa dambudziko. Izvo zvakasarudzika zvakanakira zveErbium-doped fiber amplifiers zvakazivikanwa nenyika, uye zvave zvichinyanya kushandiswa zvakanyanya. Nekudaro, Erbium-doped fiber amplifiers zvakare ine zvimwe zvinogumira. Semuenzaniso, mukutaurirana kure-kure hakugone kukwira nekudzika, iyo chiteshi bhizinesi kuonana kwakanyanya kuoma, hazvisi nyore kuwana zvikanganiso, pombi chiedza chitubu hupenyu hahurebe, nekuenderera mberi kwekuenderera mberi kweiyo optical fiber kutaurirana tekinoroji, matambudziko aya achagadziriswa zvinogutsa.
