Iyo intera yoherejwe ari ndende cyane (zirenga 100 km), ibimenyetso bya optique bizagira igihombo kinini.Mubihe byashize, abantu bakunze gukoresha optique isubiramo kugirango bongere ibimenyetso bya optique.Ubu bwoko bwibikoresho bufite aho bugarukira mubikorwa bifatika.Byasimbuwe na optique fibre amplifier.Ihame ryakazi rya optique fibre amplifier irerekanwa mumashusho hepfo.Irashobora kwongerera mu buryo butaziguye ibimenyetso bya optique bitanyuze mu nzira ya optique-amashanyarazi-optique.
Nigute fibre amplifier ikora?

Ni ubuhe bwoko bwa fibre amplifiseri ihari?
1. Erbium-yuzuye fibre amplifier (EDFA)
Erbium-Dope fibre amplifier (EDFA) igizwe ahanini na fibre erbium-dope fibre, pompe yumucyo, pompe optique, optique ya optique, hamwe na filteri ya optique.Muri byo, fibre ya erbium ni igice cyingenzi cyo kongera ibimenyetso bya optique, ikoreshwa cyane cyane kugirango igere kuri 1550 nm Band ya optique yerekana ibimenyetso, bityo rero, erbium-dope fibre amplifier (EDFA) ikora neza muburebure bwa 1530 nm kugeza 1565 nm.
Advantage:
Gukoresha ingufu za pompe nyinshi (zirenga 50%)
Irashobora mu buryo butaziguye kandi icyarimwe kongera ibimenyetso bya optique muri bande ya 1550 nm
Wunguke hejuru ya 50 dB
Urusaku ruto mu kohereza intera ndende
kubura
Erbium-ikoporora fibre amplifier (EDFA) nini
Ibi bikoresho ntibishobora gukora bihujwe nibindi bikoresho bya semiconductor
2. Raman amplifier
Raman amplifier nigikoresho cyonyine gishobora kongera ibimenyetso bya optique mumurongo wa 1292 nm ~ 1660 nm.Ihame ryakazi ryayo rishingiye ku ngaruka zo gukwirakwiza Raman muri fibre ya quartz.Nkuko bigaragara ku gishushanyo gikurikira, iyo itara rya pompe rikururwa Iyo ikimenyetso cyumucyo kidakomeye muri Mann cyunguka umurongo kandi urumuri rukomeye rwa pompe rukwirakwizwa icyarimwe muri fibre optique, ikimenyetso cyumucyo cyoroshye kizongerwaho kubera ingaruka zo gukwirakwiza Raman .
Advantage:
Ubwinshi bwamabandi akoreshwa
Irashobora gukoreshwa mugushiraho uburyo bumwe bwa fibre cabling progaramu
Irashobora kuzuza intege nke za erbium-dope fibre amplifier (EDFA)
Gukoresha ingufu nke, umuhanda muto
ibitagenda neza:
Imbaraga za pompe nyinshi
Sisitemu igoye yo kugenzura
Urusaku
3. Semiconductor optique fibre amplifier (SOA)
Semiconductor optique fibre amplifier (SOA) ikoresha ibikoresho bya semiconductor nkibintu byunguka itangazamakuru, kandi ibyapa bya optique byinjiza nibisohoka bifite ibifuniko birwanya anti-reflice kugirango birinde gutekereza kumaso yanyuma ya amplifier no gukuraho ingaruka za resonator.
Advantage:
ingano nto
Imbaraga nkeya
Inyungu yagutse ni nto, ariko irashobora gukoreshwa mumatsinda menshi atandukanye
Nibihendutse kuruta erbium-dope fibre amplifier (EDFA) kandi irashobora gukoreshwa nibikoresho bya semiconductor
Ibikorwa bine bidafite umurongo wo guhinduranya inyungu, guhinduranya ibice, guhinduranya uburebure no guhuza imivumba ine irashobora kugerwaho
ibitagenda neza:
Imikorere ntabwo iri hejuru nka erbium-dope fibre amplifier (EDFA)
