Kana kureba kwekufambisa kwakareba (kupfuura 100 km), chiratidzo chemaziso chichava nekurasikirwa kukuru.Munguva yakapfuura, vanhu vaiwanzoshandisa optical repeaters kukwidziridza chiratidzo chemaziso.Rudzi urwu rwemidziyo ine zvimwe zvinogumira mumashandisirwo anoshanda.Yakatsiviwa ne optical fiber amplifier.Nheyo yekushanda ye optical fiber amplifier inoratidzwa mumufananidzo uri pasi apa.Iyo inogona kukwidziridza zvakananga chiratidzo chemaziso pasina kuenda kuburikidza neiyo optical-electrical-optical kutendeuka.
Iyo fiber amplifier inoshanda sei?

Ndeapi marudzi efiber amplifiers aripo?
1. Erbium-doped fiber amplifier (EDFA)
Erbium-doped fiber amplifier (EDFA) inonyanya kuumbwa neerbium-doped fiber, pombi light source, optical coupler, optical isolator, uye optical filter.Pakati pavo, erbium-doped fiber chikamu chakakosha chekuwedzera kwechiratidzo, iyo inonyanya kushandiswa kuwana 1550 nm Band optical signal amplification, saka, erbium-doped fiber amplifier (EDFA) inoshanda zvakanakisisa muhuwandu hwehuwandu hwe1530 nm kusvika. 1565 nm.
Azvakanakira:
Iyo yepamusoro pombi yekushandisa simba (inopfuura 50%)
Iyo inogona zvakananga uye panguva imwe chete kukwidziridza chiratidzo chemaziso mu1550 nm bhendi
Wana pamusoro pe50 dB
Mutsindo wakaderera mukufambiswa kure-kure
kushomeka
Erbium-doped fiber amplifier (EDFA) yakakura
Iyi midziyo haigone kushanda mukubatana nemimwe semiconductor michina
2. Raman amplifier
Iyo Raman amplifier ndiyo yega mudziyo unogona kukwidziridza masaini masaini mu1292 nm ~ 1660 nm bhendi.Nheyo yayo yekushanda yakavakirwa pane yakasimudzwa yeRaman yekuparadzira mhedzisiro muquartz fiber.Sezvinoratidzwa mumufananidzo uri pasi apa, apo chiedza chepombi chinodhonzwa Kana chiedza chisina simba muMann chichiwana bandwidth uye simba rakasimba repombi chiedza rinoparidzirwa panguva imwe chete mu optical fiber, chiratidzo chisina simba chinowedzerwa nekuda kweRaman scattering effect. .
Azvakanakira:
Mabhendi akawanda anoshanda
Inogona kushandiswa mune yakaiswa single-modhi fiber cabling application
Inogona kuwedzera kushomeka kweerbium-doped fiber amplifier (EDFA)
Simba rekushandisa rakaderera, rakaderera crosstalk
kukanganisa:
High pombi simba
Complex kuwana control system
Noisy
3. Semiconductor optical fiber amplifier (SOA)
Semiconductor optical fiber amplifiers (SOA) inoshandisa semiconductor zvinhu sekuwana midhiya, uye yavo yekuona chiratidzo chekuisa uye inobuda ine anti-reflection coatings kudzivirira kufungisisa kumagumo kwechiso cheamplifier uye kubvisa mhedzisiro yeresonator.
Azvakanakira:
volume shoma
Simba rekubuda pasi
Iyo kuwana bandwidth idiki, asi inogona kushandiswa mumabhendi mazhinji akasiyana
Yakachipa kupfuura erbium-doped fiber amplifier (EDFA) uye inogona kushandiswa nemidziyo yesemiconductor.
Ina isina-mutsara mashandiro emuchinjiko-kuwana modulation, muchinjika-chikamu modulation, wavelength shanduko uye mana-wave musanganiswa anogona kuitika.
kukanganisa:
Kuita hakuna kukwira seerbium-doped fiber amplifier (EDFA)
Ruzha rwepamusoro uye kuwana kwakaderera
