Mokhoa oa ho khetha mofuta oaoptical delay lineODL

Optical Delay Lines (ODL) ke lisebelisoa tse sebetsang tse lumellang matšoao a optical hore a kenye letsoho ho tloha pheletsong ea fiber, e fetisetsoang ka bolelele bo itseng ba sebaka sa mahala, ebe se bokelloa qetellong ea fiber bakeng sa tlhahiso, e leng se etsang hore nako e liehe. Li ka sebelisoa mecheng ea puisano e potlakileng joalo ka matšeliso a PMD, li-interferometric sensors, li-telecommunications tse lumellanang, li-spectrum analyzers le mekhoa ea OCT.

Ho khetha e loketsengfiber optic lieha linee hloka ho nahanoa ka lintlha tse ngata, ho kenyelletsa nako ea ho lieha, bandwidth, tahlehelo, maemo a tikoloho, le litlhoko tse khethehileng tsa maemo a kopo. Mona ke tse ling tsa mehato ea bohlokoa le ho nahanela ho u thusa ho khetha e loketsengmohala oa ho lieha ha fiber:
1. Nako ea ho lieha: Etsa qeto ea nako e hlokahalang ea ho lieha ho ipapisitse le boemo bo itseng ba kopo.
2. Bandwidth Range: Lisebelisoa tse fapaneng li ka ba le litlhoko tse fapaneng tsa bandwidth. Mohlala, litsamaiso tsa puisano hangata li hloka bandwidth e pharalletseng, athe lisebelisoa tse ling tsa radar li ka hloka feela mats'oao ka har'a sebaka se itseng sa maqhubu. Ntle le moo, hoa hlokahala ho nahana ka litšobotsi tse fapaneng tsa bandwidth tsa fiber ea mofuta o le mong le mefuta e mengata ea fiber. Fiber ea mofuta o le mong e loketse lits'ebetso tse hole le tse phahameng tsa bandwidth, athe fiber ea multimode e loketse lits'ebetso tsa sebaka se khuts'oane.
3 Litlhoko tsa Tahlehelo: Etsa qeto ea tahlehelo e kholo e lumelletsoeng ho latela litlhoko tsa kopo. Lits'ebetsong tse sebetsang, ho tla khethoa li-fiber tsa optical tse lahleheloang tlase le lihokelo tsa boleng bo holimo ho fokotsa ho fokotsa matšoao.
4 Maemo a tikoloho: Lisebelisoa tse ling li ka hloka ts'ebetso maemong a mocheso o feteletseng, kahoo khetha li-optical fibers tse ka sebetsang ka mokhoa o tloaelehileng ka har'a mocheso o boletsoeng. Ho phaella moo, libakeng tse ling, likhoele tsa optical li hloka ho ba le matla a itseng a mochine ho thibela tšenyo.
5. Tekanyetso ea litšenyehelo: Khetha mehala ea ho lieha ea optic e bolokang litšenyehelo ho latela tekanyetso. Mehala ea ho lieha ha fiber e phahameng e kanna ea bitsa chelete e ngata, empa ea hlokahala lits'ebetsong tse itseng tsa bohlokoa.
6 Maemo a khethehileng a ts'ebeliso: Utloisisa litlhoko tse khethehileng tsa boemo bo itseng ba ts'ebeliso, joalo ka hore na tieho e ka lokisoang ea hlokahala, hore na mesebetsi e meng (joalo ka liamplifiers, filters, joalo-joalo) e hloka ho kopanngoa. Ka bokhutšoanyane, ho khetha ka katleho mohala o nepahetseng oa ho lieha ha fiber optic ho hloka hore ho nahanoe ka botlalo lintlha tse ngata. Re tšepa hore mehato le lintlha tse ka holimo li ka u thusa ho khetha mohala o nepahetseng oa ho lieha ho optic oa ODL.
