Fiber optic transceiver yog cov cuab yeej siv los xa cov teeb liab kho qhov muag hauv kev sib txuas lus fiber ntau. Nws muaj lub teeb emitter (lub teeb emitting diode los yog laser) thiab lub teeb receiver (lub teeb ntes), siv los hloov hluav taws xob teeb liab rau hauv cov teeb liab kho qhov muag thiab rov qab hloov lawv.
Fiber optic transceivers ua tus choj ntawm optical thiab hluav taws xob teeb liab hauv fiber ntau optic kev sib txuas lus, ua tiav cov ntaub ntawv ceev thiab ruaj khov. Nws tuaj yeem siv rau hauv cheeb tsam hauv cheeb tsam (LANs), thaj chaw dav dav (WANs), cov ntaub ntawv chaw sib cuam tshuam, kev sib txuas lus wireless hauv paus chaw nres tsheb, sensor tes hauj lwm, thiab lwm yam xwm txheej ceev cov ntaub ntawv xa mus.
Txoj haujlwm ua haujlwm:
Optical transmitter: Thaum tau txais cov teeb liab hluav taws xob, lub teeb pom kev zoo (xws li laser lossis LED) nyob rau hauv lub tshuab hluav taws xob kho qhov muag tau qhib, tsim cov teeb liab kho qhov muag sib xws rau cov teeb liab hluav taws xob. Cov teeb liab kho qhov muag no raug xa mus los ntawm cov fibers optical, thiab lawv qhov zaus thiab cov qauv kev hloov kho txiav txim siab cov ntaub ntawv tus nqi thiab hom kev sib kis.
Optical receiver: Lub optical receiver yog lub luag hauj lwm rau converting optical signals rov qab rau hauv hluav taws xob signals. Nws feem ntau siv photodetectors (xws li photodiodes los yog photoconductive diodes), thiab thaum lub teeb liab nkag mus rau hauv lub detector, lub teeb lub zog yog hloov dua siab tshiab rau hauv hluav taws xob teeb liab. Lub receiver demodulates lub teeb liab kho qhov muag thiab hloov nws mus rau hauv qhov qub hluav taws xob teeb liab.
Cov khoom tseem ceeb:
●Optical transmitter (Tx): lub luag hauj lwm rau kev hloov hluav taws xob teeb liab rau hauv cov teeb liab kho qhov muag thiab xa cov ntaub ntawv los ntawm fibers optical.
●Optical Receiver (Rx): Tau txais cov teeb liab kho qhov muag ntawm lwm qhov kawg ntawm cov fiber ntau thiab hloov lawv rov qab rau hauv cov teeb liab hluav taws xob rau kev ua los ntawm cov khoom txais.
● Optical connector: siv los txuas fiber ntau optic transceivers nrog optical fibers, kom ntseeg tau tias kis tau tus mob ntawm optical signals.
●Control circuit: siv los saib xyuas cov xwm txheej ntawm cov khoom siv optical transmitter thiab receiver, thiab ua kom tsim nyog hluav taws xob teeb liab kho thiab tswj.
Fiber optic transceivers txawv nyob ntawm seb lawv kis tau tus nqi, wavelength, interface hom, thiab lwm yam tsis. Cov hom kev sib txuas feem ntau suav nrog SFP, SFP +, QSFP, QSFP +, CFP, thiab lwm yam. Txhua hom kev sib txuas muaj ib qho kev thov tshwj xeeb thiab cov peev txheej ntawm daim ntawv thov. Fiber optic transceivers yog dav siv nyob rau hauv niaj hnub kev sib txuas lus teb, muab kev pab cuam tseem ceeb rau high-ceev, ntev-ntev, thiab tsis tshua muaj fiber optic kis tau tus mob.
