Qonda ubude begagasi be-850nm, 1310nm kanye ne-1550nm ku-fiber optical
Ukukhanya kuchazwa ubude bayo be-waveleng, futhi ekuxhumaneni kwe-fiber optic, ukukhanya okusetshenzisiwe kusendaweni ye-infrared, lapho ubude begagasi bokukhanya bukhulu kunokukhanya okubonakalayo.Ekuxhumaneni kwe-fiber optical, ubude begagasi obujwayelekile bungu-800 kuya ku-1600nm, kanti amaza asetshenziswa kakhulu amaza angama-850nm, 1310nm kanye no-1550nm.
Umthombo wesithombe:
Uma i-fluxlight ikhetha ubude beza beza bokudlulisa, icabangela ukulahleka kwefayibha nokuhlakazeka.Umgomo uwukudlulisa idatha eningi ngokulahleka okuncane kwefayibha ngebanga elide kakhulu.Ukulahlekelwa amandla esignali ngesikhathi sokudlulisela kuwukuncisha amandla.Ukuncipha kuhlobene nobude be-waveform, uma i-waveform iba yinde, iba yincane ukuncipha.Ukukhanya okusetshenziswe ku-fiber kunobude beza beza ende ku-850, 1310, 1550nm, ngakho ukuncishiswa kwefayibha kuncane, okuphinde kubangele ukulahleka kwefayibha encane.Futhi lawa maza amaza amathathu acishe abe ngu-zero ukumuncwa, afaneleka kakhulu ukudluliselwa kumafiber optical njengemithombo yokukhanya etholakalayo.
Umthombo wesithombe:
Ekuxhumaneni kwe-fiber optical, i-optical fiber ingahlukaniswa ibe yimodi eyodwa kanye nemodi eminingi.Isifunda se-wavelength esingu-850nm ngokuvamile siyindlela yokuxhumana ye-multi-mode optical fiber, i-1550nm imodi eyodwa, kanti i-1310nm inezinhlobo ezimbili zemodi eyodwa kanye nemodi eminingi.Ibhekisela ku-ITU-T, ukuncishiswa kwe-1310nm kunconywa ukuthi kube ≤0.4dB/km, futhi ukuncishiswa kwe-1550nm ngu-≤0.3dB/km.Kanti ukuhlulwa ku-850nm ngu-2.5dB/km.Ukulahleka kwe-fiber ngokuvamile kuncipha njengoba ubude be-waveleng bukhula.Ubude begagasi obumaphakathi obungu-1550 nm obuzungeze i-C-band (1525-1565nm) ngokuvamile bubizwa ngokuthi iwindi lokulahlekelwa yiziro, okusho ukuthi ukuncishiswa kwefayibha ye-quartz kuncane kakhulu kulobu bubude beza.
I-Beijing Rofea Optoelectronics Co., Ltd. etholakala “eSilicon Valley” yaseChina – Beijing Zhongguancun, iyibhizinisi lobuchwepheshe obuphezulu elizinikele ekuhlinzekeni izikhungo zocwaningo zasekhaya nezangaphandle, izikhungo zocwaningo, amanyuvesi kanye nabasebenzi bocwaningo lwesayensi ebhizinisi.Inkampani yethu ibambe iqhaza kakhulu ocwaningweni nasekuthuthukisweni okuzimele, ukuklama, ukukhiqiza, ukuthengiswa kwemikhiqizo ye-optoelectronic, futhi ihlinzeka ngezixazululo ezintsha nezinsizakalo eziqeqeshiwe, ezenzelwe wena uqobo abacwaningi besayensi nonjiniyela bezimboni.Ngemuva kweminyaka eminingi yokusungula izinto ezizimele, iye yakha uchungechunge olucebile noluphelele lwemikhiqizo ye-photoelectric, esetshenziswa kakhulu kumasipala, ezempi, ezokuthutha, amandla kagesi, ezezimali, ezemfundo, ezokwelapha nezinye izimboni.
