Cov ntawv OTDR siv rau DCI Box
OTDR optical time domain reflector, uas tuaj yeem ntsuas qhov ntev ntawm fiber, optical fiber transmission attenuation, splice attenuation thiab fault location, thiab lwm yam. Nws tuaj yeem siv rau kev saib xyuas optical fiber cable, fiber optic cable tsim thiab txij nkawm.
Thaum lub sijhawm kuaj OTDR, lub zog uas lub tshuab hluav taws xob tsim tawm yuav tsav LD los tsim cov teeb ci, uas raug txhaj rau hauv cov fiber ntau kom kuaj los ntawm lub coupler. Lub zog teeb mus rau hauv cov fiber ntau, vim muaj cov khoom tsis huv hauv cov fiber, cov npuas thiab lwm yam kev tawg tshwm sim, qee qhov tawg rov qab hu ua lub teeb tawg rov qab (BACK SCATTERINGLIGHT), ua ke nrog lub teeb FRESENL uas tsim los ntawm lub ntsej muag tsis sib xws ntawm cov fiber, ua ke nrog kev cuam tshuam rov qab mus rau lub coupler, mus rau hauv photodiode, mus rau hauv lub zog hluav taws xob. Lub teeb ci no tsis muaj zog heev, yog li nws raug xa mus, sau, rov ua dua, nthuav dav, nruab nrab thiab ua tiav, thiab tom qab ntawd muab cov ntaub ntawv rau lub platform tswj hwm network. Nws yog tus cwj pwm los ntawm ntau yam dynamic thiab qib siab ntawm kev daws teeb meem.
Daim Ntawv Teev Cov Ntaub Ntawv OTDR Kev Ua Haujlwm Kev txhawb nqa rau qhov deb ntawm qhov txuas fiber ntau, kev txo qis, tag nrho kev poob thiab lwm yam kev ntsuas ntawm qhov kev xeem Qhovtus lej 1qhov Chaw nres nkoj Muab 8 qhov kev sib txuas lus sib txuas (xaiv los ntawm kev hloov kho qhov muag), uas tuaj yeem txuas nrog 8-core optical fiber txuas kev sib txuas Kev ua haujlwm wavelength 1625 nm Ntau yam kev hloov pauv ≥30 dB Qhov dav ntawm lub zog txav 0.02 ~ 20 peb Qhov ntau tshaj plaws ntawm kev kuaj pom ≥80 km Kev xeem poob qhov tseeb ±0.5 dB Kev ntsuas qhov tseeb <20 m Kev tshwm sim dig muag <10 m Thaj chaw tuag ntawm kev txo qis <20 m
Daim Ntawv Thov: Nws yog qhov tsim nyog rau kev kuaj mob sai thiab kev tswj hwm centralized ntawm optical fiber faults. Siv rau DCI Box.
