Chii chinonzi "cyclic fiber mhete"? Marii yaunoziva nezvayo?
Tsanangudzo: Iyo Optical Fiber Mhete kuburikidza neyechiedza inogona kutenderera kakawanda
Iyo cyclic fiber ring ari afiber optic kifaamune iyo mwenje inogona kutenderera uye inosvika kakawanda. Iyo inonyanya kushandiswa muhurefu hwekuratidzira fiber yekukurukurirana system. Kunyangwe nehurefu hwakajeka hweOptical Fiber, chiratidzo chiratidzo chinogona kutumirwa pamusoro pematare akareba kwazvo nekudzidzira kakawanda. Izvi zvinobatsira kudzidza zvinokuvadza zvinokuvadza uye optical nellinearity iyo inokanganisa mhando yeiyo chiratidzo.
MuLaser Technology, cyclic fiber loops inogona kushandiswa kuyera mutsara welaser, kunyanya kana mutsara wacho uri mudiki kwazvo (<1khz). Uku ndiko kuwedzerwa kweiyo heterodyne linewidth nzira, iyo isingade imwezve chinongedzo laser kuwana chiratidzo kubva pachayo, icho chinoda kushandiswa kwenguva refu-madiki mitezo. Dambudziko rezvekuzvisarudzira tekinoroji ndeiyi kunonoka nguva yekunonoka kwehurongwa hwakaenzana nekudzoreredzwa kwehupamhi, uye kuti isingasviki 1khz inoda kureba mafuru.
Mufananidzo 1: Schematic Diagram yeCyclic Fiber Mhete.
Chikonzero chekutanga chekushandisa fiber zvishiro ndezvekuti svutugadzike urefu inogona kupa nguva yakareba kunonoka nekuti mwenje inofamba yakawanda inotendeukira mu fiber. Kuti uparadzanise mwenje unotapudzwa mumatare akasiyana, oriusto-Optic modulator inogona kushandiswa muchiuno kuti ubudise imwe frequency shift (semuenzaniso, 100MHZ). Nekuti iyi frequency shift yakakura zvakanyanya kupfuura mutsara wehupamhi, mwenje wakafamba nhamba dzakasiyana dzekutendeuka mune chiuno chinogona kuparadzaniswa munzvimbo yekugara. MuPhotomdetector, yekutangalaser mwenjeuye kurohwa kwechiedza mushure mekutenderera kweiyo nguva zhinji kunogona kushandiswa kuyera mutsara wehupamhi.
Kana pasina mudziyo wekuwedzera mune chiuno, kurasikirwa muAcousto-Optic modulator uye fiber yakakura kwazvo, uye kuwanda kwechiedza kuchaora zvakanyanya mushure memidziyo yakati wandei. Izvi zvinodzikisira zvakanyanya huwandu hwemabwe kana mutsara wakayerwa. Filber Amplifiers inogona kuwedzerwa kune chiuno kuti ubvise izvi zvisingabvumirwe.
Nekudaro, izvi zvinoumba dambudziko idzva: Kunyangwe iyo mwenje ichipfuura nemusangano akasiyana zvachose, iyo yekurova chiratidzo inouya kubva kune dzakasiyana mbiri dzemapikicha, ayo anoshandura fungidziro yekurova seyakazara. Iyo Optical Fiber Mhete inogona kuve yakagadzirirwa zvine musoro kuti inhibit izvi mhedzisiro. Pakupedzisira, kunzwa kweiyo cyclic fiber loop inogumira neiyo ruzha rwefiber amplifier. Izvo zvinodikanwa kuti ufunge nezve husingatarise nezve fiber uye iyo isiri-Lorentz mitsara mune data kugadzirisa
