Kana daro rekutumira rakareba zvakanyanya (rinopfuura makiromita zana), chiratidzo che optical chinorasikirwa zvikuru. Kare, vanhu vaishandisa ma optical repeaters kuti vawedzere chiratidzo che optical. Rudzi urwu rwemuchina rune zvimwe zvipingamupinyi mukushandiswa kwaro. Rwakatsiviwa ne optical fiber amplifier. Nheyo yekushanda kwe optical fiber amplifier inoratidzwa mumufananidzo uri pazasi. Inogona kuwedzera zvakananga chiratidzo che optical pasina kupfuura nepamuitiro wekushandura optical-electrical-optical.
Fiber amplifier inoshanda sei?

Ndeapi marudzi emafaibha amplifiers aripo?
1. Amplifier yefaibha yakasanganiswa neErbium (EDFA)
Erbium-doped fiber amplifier (EDFA) inonyanya kuumbwa ne erbium-doped fiber, pombi light source, optical coupler, optical isolator, uye optical filter. Pakati pazvo, erbium-doped fiber chikamu chakakosha che optical signal amplification, iyo inonyanya kushandiswa kuwana 1550 nm Band optical signal amplification, saka, erbium-doped fiber amplifier (EDFA) inoshanda zvakanyanya muhuwandu hwe wavelength kubva pa1530 nm kusvika 1565 nm.
Amukana:
Simba repombi rinoshandiswa zvakanyanya (rinopfuura 50%)
Inogona kuwedzera zvakananga uye panguva imwe chete chiratidzo che optical mubhendi re1550 nm
Wedzera pamusoro pe50 dB
Ruzha rwakaderera mukutumirwa kure
kushaya simba
Erbium-doped fiber amplifier (EDFA) yakakura
Midziyo iyi haigone kushanda pamwe chete nemimwe michina ye semiconductor
2. Raman amplifier
Raman amplifier ndiyo yega mudziyo unogona kuwedzera masaini ekuona mubhendi re1292 nm ~ 1660 nm. Nheyo yayo yekushanda yakavakirwa pamhedzisiro yekupararira kweRaman yakakurudzirwa mufiber yequartz. Sezvakaratidzwa mumufananidzo uri pazasi, kana mwenje wepombi wadhonzwa Kana chiratidzo chechiedza chisina simba muMann chawedzera bandwidth uye wave yemwenje wepombi yakasimba zvikatumirwa panguva imwe chete mufiber yekuona, chiratidzo chechiedza chisina simba chichawedzerwa nekuda kwemhedzisiro yekupararira kweRaman.
Amukana:
Mhando dzakasiyana dzemabhandi anoshanda
Inogona kushandiswa mukushandiswa kwe single-mode fiber cables
Inogona kuwedzera pane zvikanganiso zve erbium-doped fiber amplifier (EDFA)
Kushandiswa kwesimba kwakaderera, kutaura kwakaderera
kushaya:
Simba guru repombi
Sisitimu yekudzora kuwana kwakaomarara
Ruzha
3. Semiconductor optical fiber amplifier (SOA)
Semiconductor optical fiber amplifiers (SOA) inoshandisa zvinhu zve semiconductor se gain media, uye optical signal input yavo uye output ine anti-reflection coatings kudzivirira reflection pamagumo e amplifier uye kubvisa simba re resonator.
Amukana:
vhoriyamu diki
Simba rekuburitsa rakaderera
Bandwidth yekuwedzera idiki, asi inogona kushandiswa mumabhandi akasiyana-siyana
Yakachipa pane erbium-doped fiber amplifier (EDFA) uye inogona kushandiswa nemidziyo ye semiconductor
Mabasa mana asina kurongeka ekuchinjana kwekuwedzera, kushandurana kwechikamu chepakati, kushandura wavelength uye kusanganisana kwemafungu mana kunogona kuitwa
kushaya:
Kushanda zvakanaka hakuna kuenzana ne erbium-doped fiber amplifier (EDFA)
Ruzha rukuru uye kuwedzera kushoma
