Xa umgama wothumelo ude kakhulu (ngaphezu kwe-100 km), isignali ye-optical iya kuba nelahleko enkulu.Ngaphambili, abantu babedla ngokusebenzisa ii-optical repeaters ukukhulisa umqondiso wokukhanya.Olu hlobo lwezixhobo lunemida ethile kwizicelo eziphathekayo.Kufakwe iamplifier yefiber optical.Umgaqo osebenzayo we-optical fiber amplifier uboniswe kumzobo ongezantsi.Inokwandisa ngokuthe ngqo umqondiso we-optical ngaphandle kokuhamba kwinkqubo yokuguqulwa kwe-optical-electrical-optical.
Sisebenza njani iamplifier yefiber?

Zeziphi iintlobo zefiber amplifier ezikhoyo?
1. I-Erbium-doped fiber amplifier (EDFA)
I-Erbium-doped fiber amplifier (EDFA) yenziwe ikakhulu yi-erbium-doped fiber, umthombo wokukhanya wempompo, i-optical coupler, i-optical isolator, kunye nesihluzo sokucoca.Phakathi kwazo, i-erbium-doped fiber iyinxalenye ebalulekileyo yokukhulisa umqondiso we-optical, esetyenziselwa ukufezekisa i-1550 nm Band optical signal amplification, ngoko ke, i-erbium-doped fiber amplifier (EDFA) isebenza kakuhle kwi-wavelength range ye-1530 nm ukuya. 1565 nm.
Ainzuzo:
Eyona mpompo iphezulu yokusetyenziswa kwamandla (ngaphezulu kwe-50%)
Iyakwazi ngokuthe ngqo kunye kunye kunye nokukhulisa isignali ye-optical kwi-band ye-1550 nm
Fumana ngaphezulu kwe-50 dB
Ingxolo ephantsi kuthumelo lomgama omde
ukusilela
I-Erbium-doped fiber amplifier (EDFA) inkulu
Esi sixhobo asikwazi ukusebenza ngokubambisana nezinye izixhobo ze-semiconductor
2. Raman amplifier
I-amplifier ye-Raman kuphela kwesixhobo esinokwandisa iimpawu zokukhanya kwi-1292 nm ~ 1660 nm band.Umgaqo wayo wokusebenza usekelwe kwimpembelelo evuselelweyo ye-Raman yokusabalalisa kwi-quartz fiber.Njengoko kubonisiwe kumzobo ongezantsi, xa ukukhanya kwempompo kutsalwa Xa isignali yokukhanya ebuthathaka kwi-Mann ifumana i-bandwidth kunye ne-wave yepompo yokukhanya eqinile ihanjiswa ngaxeshanye kwi-fiber optical, isignali yokukhanya ebuthathaka iya kwandiswa ngenxa yesiphumo sokusasazeka kwe-Raman. .
Ainzuzo:
Uluhlu olubanzi lweebhendi ezisebenzayo
Ingasetyenziswa kusetyenziso olufakelweyo lwefayibha yendlela enye
Inokongeza kwiintsilelo ze-erbium-doped fiber amplifier (EDFA)
Ukusetyenziswa kwamandla aphantsi, i-crosstalk ephantsi
ukusilela:
Amandla ompompo aphezulu
Inkqubo yokulawula inzuzo entsonkothileyo
Kungxola
3. Semiconductor optical fiber amplifier (SOA)
I-Semiconductor optical fiber amplifiers (SOA) zisebenzisa izixhobo ze-semiconductor njengemithombo yeendaba, kwaye igalelo labo lesignali ye-optical kunye nemveliso ineengubo ezichasene ne-anti-reflection ukukhusela ukubonakaliswa kobuso bokugqibela be-amplifier kunye nokuphelisa umphumo we-resonator.
Ainzuzo:
umthamo omncinci
Amandla emveliso ephantsi
I-bandwidth yokuzuza incinci, kodwa inokusetyenziswa kwiibhendi ezininzi ezahlukeneyo
Ixabiso eliphantsi kune-erbium-doped fiber amplifier (EDFA) kwaye ingasetyenziswa kunye nezixhobo zesemiconductor.
Imisebenzi emine engeyiyo yomgca yokuguquguquka kwenzuzo yomnqamlezo, ukumodareyitha kwesigaba esinqamlezayo, ukuguqulwa kwamaza amaza kunye nokuxuba amaza amane kunokufezekiswa.
ukusilela:
Ukusebenza akukho phezulu njenge-erbium-doped fiber amplifier (EDFA)
Ingxolo ephezulu kunye nenzuzo ephantsi
