Izinzuzo Zokuzwela Izinga Lokushisa Elisabalalisiwe
Izinzwa ze-fiber optic zisebenzisa ukukhanya njengesithwali solwazi kanye ne-fiber optic njengendlela yokudlulisa ulwazi. Uma kuqhathaniswa nezindlela zokulinganisa izinga lokushisa zendabuko, ukulinganisa izinga lokushisa kwe-fiber optic okusatshalaliswa kunezinzuzo ezilandelayo:
● Akukho ukuphazamiseka kwe-electromagnetic, ukumelana nokugqwala
● Ukuqapha okungenamsebenzi ngesikhathi sangempela, ukuvikela umsindo, okuvimbela ukuqhuma
● Usayizi omncane, olula, ogobekayo
● Ukuzwela okuphezulu, impilo yenkonzo ende
● Ukulinganisa ibanga, ukulungiswa okulula
Isimiso se-DTS
I-DTS (Distributed Temperature Sensing) isebenzisa umphumela we-Raman ukukala izinga lokushisa. I-optical laser pulse ethunyelwa nge-fiber ibangela ukuthi ukukhanya okuhlakazekile kubonakale ohlangothini lwe-transmitter, lapho ulwazi luhlaziywa khona ngesimiso se-Raman kanye nesimiso se-optical time domain reflection (OTDR). Njengoba i-laser pulse isakazeka nge-fiber, kukhiqizwa izinhlobo eziningana zokuhlakazeka, phakathi kwazo i-Raman ezwela ukushintshashintsha kwezinga lokushisa, lapho izinga lokushisa liphakama, kulapho ukuqina kokukhanya okubonakalayo kukhuphuka khona.
Ukuqina kokusabalala kweRaman kulinganisa izinga lokushisa eduze kwefayibha. Isignali ye-Raman anti-Stokes ishintsha ubukhulu bayo kakhulu ngokushisa; isignali yeRaman-Stokes izinzile.
Umthombo wokukhanya wokulinganisa izinga lokushisa we-Lumispot Tech's Pulse Laser Source Series 1550nm DTS distributed temperature measurement source uwumthombo wokukhanya oshukunyiswayo owenzelwe ngqo izinhlelo zokusebenza zokulinganisa izinga lokushisa ze-fiber optic ezisakazwayo ngokusekelwe kusimiso sokusabalala kwe-Raman, esinohlelo lwangaphakathi Umklamo wendlela yokukhanya ehlelekile ye-MOPA, umklamo olungiselelwe wokukhulisa ukukhanya kwe-optical okunezigaba eziningi, ungafinyelela amandla okushaya okuphezulu kwe-3kw, umsindo ophansi, kanye nenhloso yesiginali kagesi ye-pulse encane eyakhelwe ngaphakathi ingaba umphumela we-pulse ofinyelela ku-10ns, olungisekayo nge-software pulse ububanzi kanye nemvamisa yokuphindaphinda, ingasetshenziswa kabanzi ohlelweni lokulinganisa izinga lokushisa lwe-fiber optic olusatshalaliswa okomile, ukuhlolwa kwengxenye ye-fiber optic, i-LIDAR, i-pulsed fiber laser kanye neminye imikhakha.
