Kuzamura igice cya semiconductor optique amplifier

Byongerewe imbaragasemiconductor optique amplifier

Byongerewe imbaraga za semiconductor optique amplifier ni verisiyo yazamuye ya semiconductor optique amplifier (SOA optique amplifier). Ni amplifier ikoresha semiconductor kugirango itange inyungu ziciriritse. Imiterere yacyo isa n'iya Fabry-Pero laser diode, ariko mubisanzwe isura yanyuma iba isizwe na firime irwanya kwigaragaza. Igishushanyo giheruka kirimo firime zirwanya ibitekerezo kimwe nu murongo uhindagurika hamwe nuduce twidirishya, bishobora kugabanya isura yanyuma kugeza munsi ya 0.001%. Imikorere-yongerewe imbaraga ya optique yongerera imbaraga akamaro cyane cyane mugihe cyo kongera ibimenyetso (optique), kuko hari iterabwoba rikomeye ryo gutakaza ibimenyetso mugihe cyohereza intera ndende. Kubera ko ibimenyetso bya optique byongerewe mu buryo butaziguye, uburyo gakondo bwo kubuhindura ibimenyetso byamashanyarazi mbere yuko biba byinshi. Kubwibyo, ikoreshwa ryaSOAbitezimbere cyane uburyo bwo kohereza. Ubu buryo bwikoranabuhanga bukoreshwa mugusaranganya ingufu nindishyi zigihombo mumiyoboro ya WDM.

Ibisabwa

Muri sisitemu yo gutumanaho ya fibre optique, semiconductor optique amplifier (SOA) irashobora gukoreshwa mubice byinshi byogusabwa kugirango uzamure imikorere nogukwirakwiza intera ya sisitemu yitumanaho. Ibikurikira nuburyo bumwe busanzwe bwo gukoresha SOA amplifier muri sisitemu yo gutumanaho ya fibre optique:

Preamplifier: SOAamplifierIrashobora gukoreshwa nka preamplifier kuri optique yakira iherezo rya sisitemu yo gutumanaho intera ndende hamwe na fibre optique irenga kilometero 100, kuzamura cyangwa kongera imbaraga ziva mubimenyetso bya sisitemu ndende ya optique ya fibre itumanaho, bityo bikishyura intera idahagije yo kwanduza iterwa no gusohora intege nke z'ibimenyetso bito. Byongeye kandi, SOA irashobora kandi gukoreshwa mugushira mubikorwa uburyo bwa tekinoroji ya optique ya sisitemu yo kuvugurura fibre optique.

Ibimenyetso byose bya optique: Muburyo bwa optique, uko intera yohereza yiyongera, ibimenyetso bya optique bizagenda byangirika bitewe na attenuation, gutatanya, urusaku, igihe jitter na crosstalk, nibindi. Kubwibyo rero, mugukwirakwiza intera ndende, birakenewe kwishyura indishyi za optique zangiritse kugirango amakuru yatanzwe neza. Ibimenyetso-byose byerekana ibimenyetso byerekana kongera imbaraga, kongera gukora no kongera igihe. Ibindi byongerwaho imbaraga bishobora gukorwa na optique ya optique nka semiconductor optique amplifier, EDFA na Raman amplifier (RFA).

Muri sisitemu yo guhitamo fibre optique, semiconductor optique amplifier (SOA amplifier) irashobora gukoreshwa muguhuza ibimenyetso bya optique, bityo bikazamura ibyiyumvo byukuri hamwe nukuri. Ibikurikira nuburyo bumwe busanzwe bwo gukoresha SOA muri sisitemu yo guhitamo fibre optique:

Ibipimo bya fibre optique: Shyira fibre optique kubintu bigomba gupimwa. Iyo ikintu gikorewe ibibazo, ihinduka ryimiterere rizatera impinduka nke muburebure bwa fibre optique, bityo uhindure uburebure bwumurongo cyangwa igihe cyibimenyetso bya optique kuri sensor ya PD. SOA amplifier irashobora kugera kumikorere yo hejuru mukwongerera no gutunganya ibimenyetso bya optique.

Ibipimo bya optique ya fibre optique: Muguhuza fibre optique hamwe nibikoresho byorohereza umuvuduko, mugihe ikintu cyatewe nigitutu, bizatera impinduka mugihombo cya optique muri fibre optique. SOA irashobora gukoreshwa mugukomeza ibimenyetso bya optique kugirango ugere kubipimo byumuvuduko ukabije.

Igice cya semiconductor optique amplifier SOA nigikoresho cyingenzi mubice byitumanaho rya fibre optique hamwe na optique ya fibre sensing. Mugukomeza no gutunganya ibimenyetso bya optique, byongera imikorere ya sisitemu no kumva ibyiyumvo. Izi porogaramu ningirakamaro kugirango tugere ku muvuduko wihuse, uhamye kandi wizewe wa fibre optique kimwe na optique ya fibre optique.
