Iintlobo zee-amplifiers zefayibha

Xa umgama wokudlulisela umde kakhulu (ngaphezulu kwe-100 km), isignali ye-optical iya kuba nelahleko enkulu. Ngaphambili, abantu babesebenzisa iziphindaphindo ze-optical ukukhulisa isignali ye-optical. Olu hlobo lwezixhobo lunemida ethile kwizicelo ezisebenzayo. Ithathelwe indawo yi-optical fiber amplifier. Umgaqo wokusebenza we-optical fiber amplifier uboniswe kumfanekiso ongezantsi. Ingakhulisa ngokuthe ngqo isignali ye-optical ngaphandle kokudlula kwinkqubo yokuguqulwa kwe-optical-electric-optical.

Ziziphi iintlobo zee-fiber amplifier ezikhoyo?

1. I-amplifier yefayibha efakwe i-Erbium (EDFA)

I-Erbium-doped fiber amplifier (EDFA) ikakhulu yenziwe yi-erbium-doped fiber, ipompo yokukhanya, i-optical coupler, i-optical isolator, kunye ne-optical filter. Phakathi kwazo, i-erbium-doped fiber yinxalenye ebalulekileyo yokukhulisa isignali ye-optical, esetyenziswa kakhulu ukufezekisa i-1550 nm Band optical signal amplification, ngoko ke, i-erbium-doped fiber amplifier (EDFA) isebenza kakuhle kuluhlu lwamaza ukusuka kwi-1530 nm ukuya kwi-1565 nm.

Aithuba:

Ukusetyenziswa kwamandla aphezulu kwimpompo (ngaphezulu kwe-50%)

Ingakhulisa ngokuthe ngqo kwaye ngaxeshanye isignali yokukhanya kwibhendi ye-1550 nm

Fumana ngaphezulu kwe-50 dB

Ingxolo ephantsi kwitransmission yomgama omde

ukusilela

I-Erbium-doped fiber amplifier (EDFA) inkulu kakhulu

Esi sixhobo asinakusebenza ngokubambisana nezinye izixhobo ze-semiconductor

2. Isikhulisi seRaman

I-amplifier yeRaman kuphela kwesixhobo esinokukhulisa imiqondiso ye-optical kwi-1292 nm ~ 1660 nm band. Umgaqo wayo wokusebenza usekelwe kwisiphumo sokusasazeka kweRaman esivuselelweyo kwifayibha ye-quartz. Njengoko kubonisiwe kumfanekiso ongezantsi, xa isibane sepompo sitsalwa Xa isibane esibuthathaka kwi-Mann sifumana i-bandwidth kunye ne-wave yokukhanya kwepompo enamandla zidluliselwa ngaxeshanye kwifayibha ye-optical, isibane esibuthathaka siya kwandiswa ngenxa yesiphumo sokusasazeka kweRaman.

Aithuba:

3. I-amplifier yefayibha ye-optical ye-semiconductor (SOA)

Ii-amplifier ze-semiconductor optical fiber amplifiers (SOA) zisebenzisa izixhobo ze-semiconductor njenge-gain media, kwaye igalelo lazo lesignali ye-optical kunye ne-output zine-anti-reflection coatings ukuthintela ukubonakaliswa kobuso bokugqibela be-amplifier kunye nokususa isiphumo se-resonator.

Aithuba:

ivolumu encinci

Amandla okukhupha aphantsi

I-bandwidth yokufumana inzuzo incinci, kodwa ingasetyenziswa kwiibhendi ezininzi ezahlukeneyo

Ixabiso layo liphantsi kune-erbium-doped fiber amplifier (EDFA) kwaye ingasetyenziswa nezixhobo ze-semiconductor.

Imisebenzi emine engeyiyo emgceni yokuguqulwa kwe-cross-gain, i-cross-phase modulation, i-wavelength conversion kunye ne-four-wave mixing inokuphunyezwa
