Joale, ke hobane'ng ha lebelo la phetisetso ea puisano ea fiber-optic e potlakile hakaale? Khokahano ea fiber ke eng? Melemo le mefokolo ea eona ke efe ha e bapisoa le mekhoa e meng ea puisano? Hona joale theknoloji e sebelisoa libakeng life?
Ho fetisa litaba ka khanya ka har'a fiberglass.
Joalo ka marang-rang a marang-rang, puisano ea fiber-optic ha e khone ho fihlela litlhoko tsa mobile. Bophelong ba letsatsi le letsatsi, puisano ea rona ea mehala e sebelisa marang-rang a se nang mohala, 'me boteng ba puisano ea optical ha bo bonahale bo le matla.
“Empa ha e le hantle, boitsebiso bo fetang 90% bo fetisoa ka fiber optics.Mohala oa selefouno o hokahane le setsi sa setsi ka marang-rang a se nang mohala, 'me ho fetisoa ha lipontšo pakeng tsa liteishene tsa motheo hangata ho itšetlehile ka fiber ea optical."He Zhixue, motlatsi oa motsamaisi oa Ofisi ea Lipatlisiso ea Optical System ea State Key Laboratory ea Optical Fiber Communication Network Technology, o boletse puisanong le Science and Technology Daily.
Optical fiber ke fiber ea optical e tšesaane joaloka moriri, e ka patoa ka ho toba, holimo, kapa ho behoa fatše leoatleng.Ka lebaka la boima ba eona bo bobebe, bonolo, le theko e tlaase ea ho hlahisa thepa e tala, qetellong e ile ea nkela mohala o moholo sebaka. joalo ka mokhoa o tloaelehileng oa phetiso ea mats'oao.
Ho bua ka mokhoa o bonolo, optical fiber puisano ke kopo e tloaelehileng ea puisano ea optical, joalo ka mabone a sephethephethe a telescope, joalo-joalo, ba sebelisa sepakapaka ho hasanya leseli le bonahalang, ke ea pono ea phetiso ea puisano ea optical ke tšebeliso ea fiber ea khalase leseling. tlhahisoleseding ea phetiso.
Ngaka ea puisano ea optical e ile ea bolella sci-tech letsatsi le leng le le leng hore mats'oao a optical a senyeha hanyane nakong ea phetisetso ho feta mats'oao a motlakase. O ile a hlalosa hore, ka mohlala, letšoao la optical le senyeha ho tloha ho 1 ho ea ho 0.99 ka mor'a lik'hilomithara tse 100, ha letšoao la motlakase le senyeha ho tloha ho 1 ho ea ho 0.5 ka mor'a 1 km feela.
Ho ea ka pono ea molao-motheo, lisebelisoa tsa motheo tse etsang puisano ea fiber ke optical fiber light source le optical detector.
Bokhoni bo boholo le bokhoni ba phetisetso ea sebaka se selelele
Ho ea ka litlaleho, mokhoa oa ho qetela oa ho fihlella fiber-optic broadband ke fiber-to-the-hae, ke hore, ho hokahanya fiber ka ho toba sebakeng se hlokoang ke mosebedisi, e le hore e ka fumana boitsebiso bo bongata ka ho sebelisa fiber.
"Mokhoa oa puisano o se nang mohala o ka ba le tšitiso ea motlakase, 'me mokhoa oa phetiso ea cable o bitsa chelete e ngata ho o beha. Ka lehlakoreng le leng, puisano ea optical fiber e na le melemo ea bokhoni bo boholo, bokhoni ba phetisetso ea sebaka se selelele, lekunutu le letle, le ho ikamahanya le maemo ho matla. Ho feta moo, fiber e nyane ka boholo ebile e bonolo ho e sebelisa. Kaho le tlhokomelo, litheko tsa thepa e tala le tsona li tlase haholo. Ho boletse Zhixue.
Le hoja puisano ea fiber-optic e na le melemo e ka holimo, boto ea eona e khutšoanyane e ke ke ea hlokomolohuoa. Ka mohlala, fiber e brittle ebile e robeha habonolo. Ho phaella moo, ho khaola kapa ho hokahanya ha fiber ho hloka tšebeliso ea sesebelisoa se itseng. Hoa lokela ho hlokomeloa hore kaho ea litoropong kapa likoluoa tsa tlhaho li ka baka liphoso habonolo.
Lits'ebetsong tse sebetsang, ho phethahala ha phetiso ea fiber ea optical haholo-holo ho itšetlehile ka mochine oa ho qetela oa ho fetisa optical le mochine oa ho qetela oa ho amohela optical. Sesebelisoa sa ho qetela sa ho fetisa optical se ka fetola hantle le ho fetola lets'oao la electro-optical, ka hona se fetola lets'oao la motlakase hore e be lets'oao la optical le tsamaisoang ke fiber ea optical. Leqephe la ho amohela la optical le etsa phetoho e ka morao 'me le ka boela la theola pontšo ea motlakase.Bofelo ba ho amohela optical le qetello ea ho fetisa optical li kopantsoe ke sehokelo ho cable ea optical ho hlokomela phetiso, phetisetso, kamohelo le pontšo ea tlhahisoleseling.
Thepa e amanang le boemo bo phahameng ba tlhahiso e itšetlehile ka thepa e tsoang linaheng tse ling
Hangata likhoele tsa optical tse sebelisoang hangata ke tse tloaelehileng tsa mofuta o le mong. Ka khopolo, lebelo la phetisetso ea tlhahisoleseling ka nako ea yuniti e ka bang 140 Tbit / s. Haeba lebelo la ho fetisa tlhahisoleseling le fihla moeling ona, ho tla baka tšubuhlellano ea tlhahisoleseling. Hangata fiber ea mofuta o le mong ke fiber e ka fetisang mokhoa o le mong feela.
Hajoale, puisano e tloaelehileng ea mofuta o le mong oa fiber optical ke o mong oa mekhoa ea puisano e sebelisoang hangata ke basebelisi. Bokhoni ba phetisetso ea mokhoa ona ke 16 Tbit / s, e e-so fihle ho boleng ba moeli oa theory. "Rekoto e ncha ea 1.06Pbit/s, e hatisitsoeng qalong ea selemo sena, ke phello ea tsoelo-pele ea theknoloji ea puisano ea fiber-optic ea mokhoa o le mong, empa lebelo le joalo le thata ho fihlella ts'ebeliso ea khoebo nakong e khutšoanyane ea nako.” Ho boletse Zhixue.
Ha e le hantle, ha ho bapisoa le mokhoa o le mong, mokhoa oa phetisetso ea li-fiber tse ngata o na le melemo e mengata ea ho finyella lebelo le phahameng, empa mokhoa ona o ntse o le ka pele-pele, 'me tsoelo-pele e eketsehileng ea hlokahala ho theknoloji ea mantlha, likarolo tsa bohlokoa, le lisebelisoa tsa hardware. .
Kamora lilemo tse 5 ho isa ho tse 10, tlas'a ts'usumetso ea litlhoko tsa ts'ebeliso, theknoloji ea mantlha ea 1.06Pbit/s ultra-large capacity single-mode multi-core optical fiber transmission system e ka qala ho sebelisoa maemong a itseng a khethehileng, joalo ka phetiso ea transoceanic le tse ling. setsi sa data se seholo." Ho boletse Zhixue.
Hajoale, theknoloji ea China ea puisano ea optical e ka qothisana lehlokoa le boemo bo tsoetseng pele ba machabeng, empa e ntse e tobana le mathata a mangata. Mohlala, setsi sa indasteri se amehang sea fokola, ha se na thekenoloji ea mantlha le ea boipuso, le lisebelisoa tse tala tsa fiber optic. "Hona joale, lisebelisoa tsa boemo bo holimo tse hlokahalang ho etsa lisebelisoa tsa fiber tse kang ho taka terata le fiber winding li itšetlehile ka thepa e tsoang linaheng tse ling." Ho boletse Zhixue.
Ka nako e ts'oanang, lisebelisoa tse phahameng le li-chips tse amanang le puisano ea optical fiber li laoloa haholo ke linaha tse tsoetseng pele tse kang United States le Japane.
Mabapi le sena, He Zhixue o khothalelitse hore hoa hlokahala ho matlafatsa lipatlisiso tsa motheo tsa theory, ho etsa mosebetsi o motle oa moralo oa nako e telele oa mahlale a mantlha, ho bolela esale pele mokhoa oa nts'etsopele ea thekenoloji, le ho tsoa molemong oa "ho latela morao-rao". -ela-morao-le morao-rao”.
Ho phaella moo, He Zhixue o ile a hatisa hore hoa hlokahala ho eketsa matsete a lipatlisiso le nts'etsopele, moralo le ts'ebetso ea li-chips tse phahameng le lisebelisoa tse phahameng, ho susumetsa cheseho ea litalenta tsa R & D, le ho tsepamisa maikutlo ho sireletsa katleho ea pele. "Haholo-holo, re tlameha ho etsa moralo oa boemo bo holimo, re fihlelle synergy le boqapi ho basebetsi, meaho le maano, le ho ntlafatsa bokhoni ba ts'ehetso ea liindasteri tse tsamaellanang," o boletse joalo.
