Izinzuzo zokusakazwa kwezinga lokushisa okusatshalaliswa

Izinzwa ze-fiber optic zisebenzisa ukukhanya njengokweqa imininingwane kanye ne-fiber optics njengendlela yokuhambisa imininingwane. Qhathanisa nezindlela zokulinganisa zokushisa zendabuko, ukusatshalaliswa kwe-fiber optic lokushisa kunezindlela ezilandelayo:

● Akukho ukuphazanyiswa kwe-electromagnetic, ukumelana nokugqwala
● Ukuqapha nje kwesikhathi sangempela, ukufakwa komsindo okuzwakalayo, ubufakazi bookuqhuma
● Usayizi omncane, esingasindi, siqine
● Ukuzwela okuphezulu, impilo yenkonzo ende
● Ukulinganisa ibanga, ukulungiswa okulula

Isimiso se-DTS

I-DTS (ukusatshalaliswa kwezinga lokushisa Ukuzwa) kusebenzisa umphumela we-raman ukukala lokushisa. I-Optical Laser Pulse ithunyelwe nge-fiber edala ukuthi ukukhanya okufihliwe kuboniswe ohlangothini lwe-transmitter, lapho ulwazi luhlaziywa khona ngomgomo we-raman kanye ne-Optical Time Domain Reflection (OTDR). Njengoba i-laser pulse isakaza ngefafa, kwakhiqizwa izinhlobo eziningi zokusakazeka, phakathi kwazo iRaman zizwela ekuphumeni kokushisa, okuphezulu okushisa, ubukhulu bokukhanya okusobala.

Ukuqina kokusakazeka kukaRaman kulinganisa izinga lokushisa emgodini. Isiginali yeRaman Anti-Stokes ishintsha ama-amplitudwal ayo kakhulu ngokushisa; Isiginali yeRaman-Stokes zizinzile.

Uhlelo lokulinganisa lokushisa luqukethe isilawuli (umthombo we-laser, i-generator ye-pulse ye-OTDR noma i-code generator yokuhlangana kwekhodi noma imodyuli ye-hf kanye ne-microprocessor) ne-quartz glass fiber) ne-quartz glass fiber) kanye nenzwa yokushisa yocingo.

I-Lumuspot Tech Pulse Laser Source Series 1550NM DTS isatshalaliswe umthombo wokushisa wokushisa umthombo wokukhanya okukhanyayo oklanyelwe izinhlelo zokusebenza ezisatshalaliswa kakhulu ezisuselwa kunqubo yokusakazeka ye-ram optic yokuvalwa kwezingathwa ngokususelwa kunqubo yokusakazeka ye-Raman I-MOPA eyakheke kahle indlela ye-Optical Path, ukwakheka okwenziwe kahle kokukhuliswa kwamandla aphezulu, kungafinyelela amandla we-3kW Peal Pulse, i-Noise ephansi ye-pulse esheshayo ingaba yi-10ns Pulse yokushisa, i-fiber opting test, i-lindic, i-laser ye-fiber eyomile kanye nezinye izinkambu.
