Qonda ubude be-wavelengths be-850nm, 1310nm kunye ne-1550nm kwi-optical fiber
Ukukhanya kuchazwa bubude bayo obuphezulu, kwaye kunxibelelwano lwe-fiber optic, ukukhanya okusetyenziswayo kukwindawo ye-infrared, apho ubude bokukhanya bukhulu kunobokukhanya okubonakalayo. Kunxibelelwano lwe-optical fiber, ubude bokukhanya obuqhelekileyo buyi-800 ukuya kwi-1600nm, kwaye ubude bokukhanya obusetyenziswa kakhulu yi-850nm, 1310nm kunye ne-1550nm.
Umthombo womfanekiso:
Xa i-fluxlight ikhetha ubude be-transmission wavelength, ikakhulu iqwalasela ukulahleka kwefayibha kunye nokusasazeka kwayo. Injongo kukudlulisa idatha eninzi kunye nokulahleka kwefayibha okuncinci kumgama omde. Ukulahleka kwamandla esignali ngexesha lokudluliselwa kukuncitshiswa. Ukuncitshiswa kunxulumene nobude be-waveform, okukhona ubude be-waveform, kokukhona ukuncitshiswa kuncinci. Ukukhanya okusetyenziswe kwifayibha kunobude be-waveform obude kwi-850, 1310, 1550nm, ngoko ke ukuncitshiswa kwefayibha kuncinci, nto leyo ekwabangela ukulahleka kwefayibha okuncinci. Kwaye la ma-wavelength amathathu aphantse angabikho, afanelekileyo kakhulu ukudluliselwa kwi-optical fibers njengemithombo yokukhanya ekhoyo.
Umthombo womfanekiso:
Kwindlela yokunxibelelana ngefayibha ye-optical, ifayibha ye-optical inokwahlulwa ibe yi-single-mode kunye ne-multi-mode. Ummandla we-wavelength ye-850nm udla ngokuba yindlela yokunxibelelana ngefayibha ye-optical ye-multi-mode, i-1550nm yi-single-mode, kwaye i-1310nm ineentlobo ezimbini ze-single-mode kunye ne-multi-mode. Ngokubhekiselele kwi-ITU-T, ukuncitshiswa kwe-1310nm kucetyiswa ukuba kube yi-≤0.4dB/km, kwaye ukuncitshiswa kwe-1550nm yi-≤0.3dB/km. Kwaye ilahleko kwi-850nm yi-2.5dB/km. Ilahleko yefayibha ngokubanzi iyancipha njengoko ubude be-wavelength busanda. Ububanzi be-wavelength ye-1550 nm ejikeleze i-C-band (1525-1565nm) budla ngokuba yi-zero loss window, oko kuthetha ukuba ukuncitshiswa kwefayibha ye-quartz yeyona incinci kule wavelength.
I-Beijing Rofea Optoelectronics Co., Ltd. ekwi "Silicon Valley" yaseTshayina – iBeijing Zhongguancun, lishishini elinobuchwepheshe obuphezulu elizinikele ekukhonzeni amaziko ophando asekhaya nangaphandle, amaziko ophando, iiyunivesithi kunye nabasebenzi bophando lwezesayensi kwishishini.
