Qonda ubude bamaza obungu-850nm, 1310nm kanye no-1550nm ku-fiber optical
Ukukhanya kuchazwa ubude bawo obude, futhi ekuxhumaneni kwe-fiber optic, ukukhanya okusetshenziswayo kusesifundeni se-infrared, lapho ubude bawo obude bokukhanya bukhulu kunobokukhanya okubonakalayo. Ekuxhumaneni kwe-fiber optical, ubude bawo obujwayelekile bungu-800 kuya ku-1600nm, kanti ubude bawo obuvame ukusetshenziswa bungu-850nm, 1310nm kanye no-1550nm.
Umthombo wesithombe:
Uma ukukhanya kwe-fluxlight kukhetha ubude be-wavelength yokudlulisela, kucatshangelwa kakhulu ukulahleka kwe-fiber kanye nokusabalala kwayo. Umgomo uwukudlulisa idatha eningi kakhulu ngokulahlekelwa okuncane kwe-fiber ebangeni elide kakhulu. Ukulahlekelwa amandla esignali ngesikhathi sokudlulisela kuwukuncipha. Ukuncipha kuhlobene nobude be-waveform, uma i-waveform ide, kulapho ukuncipha kuncane khona. Ukukhanya okusetshenziswa ku-fiber kunobude be-wavelength obude obungu-850, 1310, 1550nm, ngakho-ke ukuncipha kwe-fiber kuncane, okuholela nasekulahlekelweni okuncane kwe-fiber. Futhi lawa ma-wavelength amathathu cishe awakwazi ukumuncwa, afaneleka kakhulu ukudluliselwa kuma-optical fibers njengemithombo yokukhanya etholakalayo.
Umthombo wesithombe:
Ekuxhumaneni nge-optical fiber, i-optical fiber ingahlukaniswa ibe yi-single-mode kanye ne-multi-mode. Isifunda se-wavelength esingu-850nm ngokuvamile siyindlela yokuxhumana nge-optical fiber yemodi eminingi, i-1550nm iyi-single-mode, kanti i-1310nm inezinhlobo ezimbili ze-single-mode kanye ne-multi-mode. Uma sibhekisela ku-ITU-T, ukuncishiswa kwe-1310nm kunconywa ukuthi kube yi-≤0.4dB/km, kanti ukuncishiswa kwe-1550nm kungu-≤0.3dB/km. Futhi ukulahlekelwa ku-850nm kungu-2.5dB/km. Ukulahleka kwe-fiber ngokuvamile kuncipha njengoba ubude be-wavelength bukhuphuka. Ububanzi be-wavelength obuphakathi buka-1550 nm obuzungeze i-C-band (1525-1565nm) buvame ukubizwa ngokuthi i-zero loss window, okusho ukuthi ukuncishiswa kwe-quartz fiber kuncane kakhulu kule wavelength.
I-Beijing Rofea Optoelectronics Co., Ltd. etholakala “eSigodini saseSilicon” saseShayina – i-Beijing Zhongguancun, iyibhizinisi lobuchwepheshe obuphezulu elizinikele ekukhonzeni izikhungo zocwaningo zasekhaya nezangaphandle, izikhungo zocwaningo, amanyuvesi kanye nabasebenzi bocwaningo lwesayensi yebhizinisi. Inkampani yethu ihileleke kakhulu ocwaningweni oluzimele kanye nentuthuko, ukuklama, ukukhiqiza, ukuthengisa imikhiqizo ye-optoelectronic, futhi inikeza izixazululo ezintsha kanye nezinsizakalo zobungcweti, ezenzelwe wena kubacwaningi besayensi kanye nonjiniyela bezimboni. Ngemva kweminyaka eminingi yokusungula izinto ezintsha, yakhe uchungechunge olucebile noluphelele lwemikhiqizo ye-photoelectric, esetshenziswa kabanzi embonini kamasipala, yezempi, yezokuthutha, yamandla kagesi, yezezimali, yezemfundo, yezokwelapha kanye neminye imboni.
