Masaisai emwenje ndiwo mwaranzi wemagetsi anogadzirwa nemaerekitironi mukufamba kweatomu.Kufamba kwemaerekitironi mumaatomu ezvinhu zvakasiyana kwakasiyana, saka masaisai echiedza aanoburitsa akasiyanawo.
Spectrum ndiyo pateni yechiedza chemonochromatic yakapatsanurwa neiyo dispersion system (yakadai seprism uye grating) mushure mekunge mwenje wepolychromatic wapatsanurwa neiyo dispersion system, iyo inorongwa mukutenderera zvichienderana newavelength (kana frequency).Inonzi optical spectrum yakazara.
Kana tichiyedza iyo transmitter tosa, isu tinowanzo sanganisira parameter, SMSR (Side Mode Suppression Ratio).Chiyero chehuwandu hwekukosha kweiyo main mode kusimba kune iyo side mode kusimba inonzi side mode suppression ratio, inova chiratidzo chakakosha cheiyo longitudinal mode performance.Kazhinji, kana uchiyera iyo yedivi nzira yekuramba reshiyo, inoda kushandiswa pamwe chete neyemaka uye ongororo mu spectral analyzer.Mugadziri anoshandiswa kuona iyo yepakati wave peak uye yepamusoro yechipiri wave peak.Verenga nhongonya mbiri.The side mode rejection reshiyo ndiwo mutsauko wesimba remazinga pakati pemapikisi maviri.Inogona kuverengwa kuburikidza ne-sub-sarudzo mukuongorora.
Inotsanangurwa sechiyero cheiyo yekutanga longitudinal mode optical simba M1 uye yakazara side mode optical simba M2 pasi pemamiriro ekuzara modulation.
Iyo calculation formula ndeye:
SMSR=10*lg(M1/M2)
Muiyo optical transmitter, inowanzotsanangurwa kuti SMSR yakakura kupfuura 30dB;ndiko kuti, iyo optical simba rekutanga longitudinal modhi inopfuura 1000 times the maximum side mode optical power.Iyo yakakwirira kukosha kweSMSR, iyo yakanyanya kukoshesa nzira yechiedza.Sezvinoratidzwa pamufananidzo uri pazasi: iyo SMSR ndeye 51dB
Iri pamusoro ndiyo tsananguro yeruzivo rweLightwave yakaunzwa neShenzhen HDV Phoelectron Technology Co., Ltd., inova inogadzira kutaurirana inogadzira uye inogadzira kambani yezvigadzirwa zvekutaurirana.Tikugashirei kushanyira yeduchigadzirwa peji.Ndinotenda nekuverenga chinyorwa ichi.
