Qonda ubude be-850nm, 1310nm kunye ne-1550nm kwifiber optical

Ukukhanya kuchazwa ngobude bayo, kwaye kunxibelelwano lwefiber optic, ukukhanya okusetyenzisiweyo kukummandla we-infrared, apho ubude bokukhanya bukhulu kunokukhanya okubonakalayo. Kunxibelelwano lwefiber optical, ubude obuqhelekileyo yi-800 ukuya kwi-1600nm, kwaye awona maza asetyenziswa ngokuqhelekileyo yi-850nm, 1310nm kunye ne-1550nm.

Umthombo womfanekiso:

Xa i-fluxlight ikhetha i-wavelength yothumelo, iqwalasela ukulahleka kwefayibha kunye nokusasazeka. Injongo kukuhambisa eyona datha incinci ilahleko yefayibha kumgama omde. Ukuphulukana namandla omqondiso ngexesha losulelo kukuthomalalisa. Ukuthomalalisa kunxulumene nobude befomati yamaza, okukhona i-waveform inde, incinci i-attenuation. Ukukhanya okusetyenziswe kwifiber kunobude obude kwi-850, 1310, 1550nm, ngoko ke ukuthotywa kwefiber kuncinci, okukhokelela ekulahlekeni okuncinci kwefayibha. Kwaye la maza mathathu aphantse afunxa u-zero, wona afaneleke kakhulu ukugqithiselwa kwiintsinga ezibonakalayo njengemithombo yokukhanya ekhoyo.

Umthombo womfanekiso:

Kunxibelelwano lwefiber optical, ifayibha ebonakalayo inokwahlulwa ibe yimowudi enye kunye neendlela ezininzi. Ummandla we-850nm we-wavelength ngokuqhelekileyo yindlela yokunxibelelana ye-fiber optical multi-mode, i-1550nm yindlela enye, kwaye i-1310nm ineentlobo ezimbini zendlela enye kunye ne-multi-mode. Ngokubhekiselele kwi-ITU-T, i-attenuation ye-1310nm inconywa ukuba ibe ngu-≤0.4dB / km, kunye nokunciphisa i-1550nm ngu-≤0.3dB / km. Kwaye ilahleko kwi-850nm yi-2.5dB/km. Ilahleko yeFayibha ngokubanzi iyancipha njengoko iwavelength ikhula. Ubude obuphakathi be-1550 nm malunga ne-C-band (1525-1565nm) idla ngokubizwa ngokuba yi-zero loss window, okuthetha ukuba ukuthotywa kwefiber yequartz yeyona nto incinci kolu bude bamaza.

I-Beijing Rofea Optoelectronics Co., Ltd. ebekwe eTshayina “kwiSilicon Valley” – iBeijing Zhongguancun, lishishini lobugcisa obuphezulu obuzinikele ekukhonzeni amaziko ophando asekhaya nawangaphandle, amaziko ophando, iiyunivesithi kunye nabasebenzi bophando lwezenzululwazi kushishino. Inkampani yethu ibandakanyeka ikakhulu kuphando oluzimeleyo kunye nophuhliso, uyilo, ukuvelisa, ukuthengisa iimveliso ze-optoelectronic, kwaye ibonelela ngezisombululo ezintsha kunye neenkonzo zobuchwephesha, ezenzelwe umntu abaphandi besayensi kunye neenjineli zeshishini. Emva kweminyaka yokwenziwa kwezinto ezizimeleyo, yenze uluhlu olutyebileyo nolugqibeleleyo lweemveliso zombane, ezisetyenziswa kakhulu kumasipala, emkhosini, kwezothutho, kumandla ombane, ezemali, ezemfundo, ezonyango kunye namanye amashishini.
