Ingantaccen amplifier na gani na semiconductor

An ingantaamplifier na gani na semiconductor

Ingantaccen amplifier na gani na semiconductor sigar haɓakawa ce ta amplifier na gani na semiconductor (SOA amplifier na gani). Amplifier ne wanda ke amfani da semiconductors don samar da matsakaicin riba. Tsarinsa yayi kama da na diode na laser na Fabry-Pero, amma yawanci fuskar ƙarshe an lulluɓe shi da fim ɗin hana haske. Sabon ƙirar ya haɗa da fina-finan hana haske da kuma jagororin raƙuman ruwa masu karkata da yankunan taga, waɗanda zasu iya rage hasken fuskar ƙarshe zuwa ƙasa da 0.001%. Amplifier na gani masu inganci suna da amfani musamman lokacin da ake ƙara siginar gani (na gani), saboda akwai babbar barazanar asarar sigina yayin watsawa mai nisa. Tunda siginar gani tana ƙaruwa kai tsaye, hanyar gargajiya ta canza ta zuwa siginar lantarki kafin ta zama mai amfani. Saboda haka, amfani daSOAyana inganta ingancin watsawa sosai. Wannan fasaha yawanci ana amfani da ita don rarraba wutar lantarki da diyya ta asara a cikin hanyoyin sadarwar WDM.

Yanayin aikace-aikace

A cikin tsarin sadarwa na fiber optical, ana iya amfani da na'urorin ƙara haske na semiconductor optical amplifiers (SOA) a fannoni daban-daban na aikace-aikace don haɓaka aiki da nisan watsawa na tsarin sadarwa. Ga wasu aikace-aikacen gama gari na amfani da na'urar ƙara haske ta SOA a cikin tsarin sadarwa na fiber optical:

Mai ƙarawa: SOAna'urar ƙara ƙarfin ganiana iya amfani da shi azaman preamplifier a ƙarshen karɓar haske a cikin tsarin sadarwa mai nisa tare da zaruruwan gani sama da kilomita 100, yana haɓakawa ko ƙara ƙarfin fitowar sigina a cikin tsarin sadarwa na zaruruwan gani na nesa, ta haka yana rama ƙarancin nisan watsawa wanda rashin ƙarfin fitarwa na ƙananan sigina ya haifar. Bugu da ƙari, ana iya amfani da SOA don aiwatar da fasahar sake farfaɗo da siginar hanyar sadarwa ta gani a cikin tsarin sadarwa na zaruruwan gani.

Sabunta siginar gani-da-gani: A cikin hanyoyin sadarwa na gani-da-gani, yayin da nisan watsawa ke ƙaruwa, siginar gani-da-gani za ta lalace saboda raguwa, wargajewa, hayaniya, jitter na lokaci da kuma magana ta crosstalk, da sauransu. Saboda haka, a cikin watsawa mai nisa, ya zama dole a rama lalacewar siginar gani don tabbatar da daidaiton bayanan da aka watsa. Sabunta siginar gani-da-gani yana nufin sake haɓaka, sake tsarawa da sake tsara lokaci. Ana iya ci gaba da ƙara faɗaɗawa ta hanyar amplifiers na gani kamar semiconductor optical amplifiers, EDFA da Raman amplifiers (RFA).

A cikin tsarin firikwensin fiber na gani, na'urorin ƙara haske na semiconductor (Amplifier SOA) ana iya amfani da shi don ƙara girman siginar gani, ta haka yana haɓaka hankali da daidaiton na'urori masu auna firikwensin. Ga wasu aikace-aikacen gama gari na amfani da SOA a cikin tsarin firikwensin fiber na gani:

Ma'aunin ma'aunin zare na gani: Gyara zaren gani a kan abin da ake buƙatar auna ma'auninsa. Lokacin da abin ya fuskanci ma'aunin, canjin ma'aunin zai haifar da ɗan canji a tsawon zaren gani, ta haka yana canza tsawon tsayin ko lokacin siginar gani zuwa firikwensin PD. Amplifier na SOA zai iya cimma babban aikin ji ta hanyar ƙarawa da sarrafa siginar gani.

Ma'aunin matsin lamba na zare: Ta hanyar haɗa zare na gani da kayan da ke da saurin matsi, lokacin da wani abu ya fuskanci matsin lamba, zai haifar da canje-canje a cikin asarar gani a cikin zare na gani. Ana iya amfani da SOA don faɗaɗa wannan siginar gani mai rauni don cimma ma'aunin matsin lamba mai matuƙar tasiri.

SOA na'urar ƙara haske ta semiconductor wata babbar na'ura ce a fannin sadarwa ta fiber optic da kuma gano fiber optic. Ta hanyar ƙara haske da sarrafa siginar gani, yana ƙara ƙarfin aiki da kuma fahimtar tsarin. Waɗannan aikace-aikacen suna da mahimmanci don cimma sadarwa mai sauri, karko da inganci ta fiber optic da kuma ingantaccen fahimtar fiber optic.
