Dab tsi yog qhov tseem ceeb ntawm kev sib txuas lus fiber ntau optical?
(1) Optical transmitter
Optical transmitter yog optical transceiver uas paub txog kev hloov hluav taws xob / kho qhov muag. Nws muaj lub teeb ci, tsav tsheb thiab modulator. Nws txoj haujlwm yog los hloov kho lub teeb nthwv dej tawm los ntawm lub teeb pom kev los ntawm lub teeb liab hluav taws xob los ntawm lub davhlau ya nyob twg los ua lub teeb pom kev hloov pauv, thiab tom qab ntawd ob peb lub teeb liab modulated rau ib qho khoom siv fiber ntau lossis cable rau kev sib kis. Lub davhlau ya nyob twg hluav taws xob yog ib qho khoom siv hluav taws xob sib txuas lus.
(2) Optical receiver
Optical receiver yog optical transceiver uas paub txog kev hloov kho qhov muag / hluav taws xob. Nws muaj ib tug optical detector thiab ib tug optical amplifier. Nws txoj haujlwm yog los hloov cov teeb liab kho qhov muag kis los ntawm optical fiber lossis optical cable mus rau hauv lub teeb liab hluav taws xob los ntawm photodetector, thiab tom qab ntawd ua kom lub zog hluav taws xob tsis muaj zog mus rau theem txaus los ntawm amplifying circuit, thiab xa mus rau qhov kawg ntawm qhov tau txais. kawg rau kev kos duab.
(3) Optical fiber lossis optical cable
Optical fiber los yog optical cable tsim txoj kev sib kis ntawm lub teeb. Nws txoj haujlwm yog ua ob peb lub teeb liab dimmed los ntawm tus xa ntawv kawg mus rau lub teeb pom kev ntawm lub receiver kawg tom qab kev sib kis mus ntev ntawm optical fiber lossis cable kom tiav cov haujlwm ntawm kev xa cov ntaub ntawv.
(4) Repeater
Lub repeater yog tsim los ntawm lub teeb pom kev, lub teeb pom kev zoo thiab kev txiav txim siab rov tsim hluav taws xob. Nws muaj ob txoj haujlwm: ib qho yog txhawm rau txhawm rau txo qis ntawm cov teeb liab kho qhov muag thaum nws kis tau rau hauv qhov muag fiber ntau; Lwm qhov yog los daws qhov impulse ntawm waveform distortion.
(5) Passive li xws li optical fiber connectors thiab couplers
Txij li qhov ntev ntawm fiber ntau optical los yog optical cable yog txwv los ntawm cov txheej txheem kho qhov muag fiber ntau thiab cov kev tsim kho ntawm cov khoom siv kho qhov muag, thiab qhov ntev ntawm cov khoom siv kho qhov muag kuj raug txwv (xws li 1Km). Yog li ntawd, cov kab hluav taws xob kho qhov muag yuav muaj teeb meem ntawm kev sib txuas ntau yam khoom siv kho qhov muag. Yog li ntawd, kev sib txuas ntawm optical fibers thiab kev sib txuas thiab coupling ntawm optical fibers thiab optical transceivers yog indispensable rau kev siv ntawm passive Cheebtsam xws li optical fiber connectors thiab couplers.
