Yakawedzerwaamplifier ye optical ye semiconductor
Iyo semiconductor optical amplifier yakawedzerwa ishanduro yakagadziridzwa ye semiconductor optical amplifier (SOA optical amplifier). I amplifier inoshandisa semiconductors kupa gain medium. Maumbirwo ayo akafanana neeFabry-Pero laser diode, asi kazhinji chiso chekupedzisira chinoputirwa nefirimu rinodzivirira kupenya. Dhizaini yazvino inosanganisira mafirimu anodzivirira kupenya pamwe nema waveguides akatsveyama uye nzvimbo dzemahwindo, izvo zvinogona kuderedza kupenya kwechiso chekupedzisira kusvika pasi pe0.001%. Ma amplifier epamusoro-soro e optical amplifiers anobatsira zvikuru pakuwedzera masaini (optical), sezvo paine njodzi yakakura yekurasikirwa nechiratidzo panguva yekutumira kure. Sezvo chiratidzo che optical chichiwedzerwa zvakananga, nzira yechinyakare yekushandura kuita chiratidzo chemagetsi isati yatanga inova isingachashandiswi. Nokudaro, kushandiswa kweSOAinovandudza zvakanyanya mashandiro ekutumira. Iyi tekinoroji inowanzo shandiswa pakupatsanura simba uye kubhadhara kurasikirwa muma network eWDM.
Mamiriro ekushandisa
Muma optical fiber communication systems, semiconductor optical amplifiers (SOA) inogona kushandiswa munzvimbo dzakasiyana siyana dzekushandisa kuti iwedzere kushanda uye daro rekutumira system yekutaurirana. Izvi zvinotevera zvimwe zvezvinowanzo shandiswa pakushandisa SOA amplifier muma optical fiber communication systems:
Chinosimudzira: SOAamplifier yemazisoinogona kushandiswa se preamplifier panzvimbo inogamuchira masaini mumasisitimu ekutaurirana ari kure ane mafirita anodarika makiromita zana, zvichiwedzera kana kuwedzera simba remasaini anobuda mumasisitimu ekutaurirana mafirita ari kure, nokudaro zvichiripa daro risina kukwana rekutumira rinokonzerwa nekubuda kusina simba kwemasaini madiki. Uyezve, SOA inogona zvakare kushandiswa kushandisa tekinoroji yekuvandudza masaini emagetsi mumasisitimu ekutaurirana mafirita.
Kugadziriswazve kwechiratidzo chemaziso: Munetwork dzemaziso, sezvo daro rekutumira richiwedzera, masaini emaziso anoderera nekuda kwekuderera, kupararira, ruzha, kusvetuka kwenguva uye kutaura kwepadivi, nezvimwewo. Saka, mukufambiswa kwechiratidzo kure, zvinodikanwa kutsiva masaini emaziso akaora kuti uve nechokwadi chekuti ruzivo rwunotumirwa rwakarurama. Kugadziriswazve kwechiratidzo chemaziso kunoreva kukwidziridzwazve, kuumbwazve uye kudzokororwa kwenguva. Kuwedzera kwekuwedzera kunogona kuitwa nema amplifiers emaziso akadai se semiconductor optical amplifiers, EDFA uye Raman amplifiers (RFA).
Mumasisitimu ekuona fiber ye optical, ma amplifiers e optical e semiconductor (SOA amplifier) inogona kushandiswa kuwedzera masaini ekuona, nokudaro ichivandudza kunzwisisika uye kururama kwemasensa. Izvi zvinotevera mamwe mashandisirwo akajairika ekushandisa SOA mumasisitimu ekuona fiber ekuona:
Kuyerwa kwekumanikidzwa kwefiber ye optical: Gadzirisa fiber ye optical pachinhu chine kumanikidzwa kwacho kunofanirwa kuyerwa. Kana chinhu chacho chikamanikidzwa, kuchinja kwekumanikidzwa kwacho kuchakonzera shanduko diki pakureba kwefiber ye optical, nokudaro kuchichinja urefu hwewavelength kana nguva yesignal ye optical kuenda kuPD sensor. SOA amplifier inogona kuwana kushanda kwepamusoro kwe sensor nekuwedzera uye kugadzirisa chiratidzo che optical.
Kuyerwa kwekumanikidzwa kwefiber ye optical: Nekubatanidza fiber ye optical nezvinhu zvinonzwa kumanikidzwa, kana chinhu chikamanikidzwa, zvinokonzeresa shanduko mukurasikirwa kwe optical mukati me fiber ye optical. SOA inogona kushandiswa kuwedzera chiratidzo ichi chisina simba che optical kuti chiyere kumanikidzwa kwakanyanya.
SOA chishandiso che semiconductor optical amplifier chinhu chakakosha mukukurukurirana kwe optical fiber uye optical fiber sensor. Nekuwedzera uye kugadzirisa masaini e optical, inowedzera mashandiro esystem uye kunzwa kwekunzwa. Mashandisirwo aya akakosha pakuwana kutaurirana kwe optical fiber nekukurumidza, kwakasimba uye kwakavimbika pamwe nekuona fiber fiber kwakarurama uye kunoshanda.
