Mokhoa oa ho khetha mofuta oamohala oa tieho oa opticalODL

Methapo ea ho lieha ha Optical (ODL) ke disebediswa tse sebetsang tse dumellang matshwao a optical ho kenngwa ho tloha pheletsong ya faeba, a fetisetswa ka bolelele bo itseng ba sebaka se lokolohileng, ebe a bokellwa pheletsong ya faeba bakeng sa tlhahiso, e leng se fellang ka tieho ya nako. Di ka sebediswa marangrang a puisano a lebelo le hodimo jwalo ka puseletso ya PMD, di-sensor tsa interferometric, dikgokahano tsa mohala tse kopaneng, di-spectrum analyzers, le ditsamaiso tsa OCT.

Ho khetha e nepahetsengmohala oa tieho oa faeba opticho hloka ho nahaneloa ka lintlha tse ngata, ho kenyeletsoa nako ea tieho, bandwidth, tahlehelo, maemo a tikoloho, le litlhoko tse itseng tsa maemo a ts'ebeliso. Mona ke mehato le lintlha tsa bohlokoa tse tla u thusa ho khetha e loketseng.mohala oa tieho ea faeba:
1. Nako ea tieho: Fumana nako ea tieho e hlokahalang ho latela boemo bo itseng ba kopo.
2. Sebaka sa Bandwidth: Ditshebediso tse fapaneng di ka ba le ditlhoko tse fapaneng tsa bandwidth. Mohlala, ditsamaiso tsa puisano hangata di hloka bandwidth e pharaletseng, ha ditsamaiso tse ding tsa radar di ka hloka matshwao feela ka hara sebaka se itseng sa maqhubu. Ho phaella moo, ho hlokahala ho nahana ka dibopeho tse fapaneng tsa bandwidth tsa mefuta ya faeba ya mokgwa o le mong le mefuta ya faeba ya mokgwa o le mong. Faeba ya mokgwa o le mong e loketse ditshebediso tsa sebaka se selelele le bandwidth e phahameng, ha faeba ya mokgwa o mongata e loketse ditshebediso tsa sebaka se sekgutshwane.
3 Litlhoko tsa tahlehelo: Fumana tahlehelo e kholo ka ho fetisisa e lumelletsoeng ho latela litlhoko tsa ts'ebeliso. Lits'ebetsong tse sebetsang, likhoele tsa optical tse lahleheloang ke tahlehelo e tlase le lihokelo tsa boleng bo holimo li tla khethoa ho fokotsa ho fokotseha ha lets'oao.
4 Maemo a tikoloho: Ditshebediso tse ding di ka hloka hore ho sebetswe mochesong o feteletseng, kahoo kgetha difaeba tsa optical tse ka sebetsang ka tlwaelo ka hara mocheso o boletsweng. Ho phaella moo, dibakeng tse itseng, difaeba tsa optical di hloka ho ba le matla a itseng a mechini ho thibela tshenyo.
5. Tekanyetso ea litšenyehelo: Khetha mela ea tieho ea optic e theko e tlaase ho latela tekanyetso. Mela ea tieho ea fiber e sebetsang hantle e ka ba theko e boima, empa ea hlokahala lits'ebetsong tse itseng tsa bohlokoa.
6 Maemo a itseng a tshebediso: Utloisisa ditlhoko tse itseng tsa boemo bo itseng ba tshebediso, jwalo ka hore na tieho e ka fetolwang e a hlokahala, hore na mesebetsi e meng (jwalo ka di-amplifier, di-filter, jj.) e hloka ho kopanngwa. Ka bokhutshwane, ho kgetha mohala o loketseng wa tieho ya fiber optic ka katleho ho hloka ho nahanisiswa ka botlalo ha dintlha tse ngata. Re tshepa hore mehato le dintlha tse ka hodimo di ka o thusa ho kgetha mohala o loketseng wa tieho ya optic ODL.
