2. Dab tsi yog Optical Cord?
Ib txoj hlua kho qhov muag-tseem hu ua a digital optical cable lossis TOSLINK- yog ib lub cable uas nqa cov ntaub ntawv suab digital ntawm lub teeb pulses los ntawm cov fiber ntau nyias. Tsis zoo li tooj liab-raws li cables, nws siv cov iav los yog yas fiber ntau los xa cov ntaub ntawv, ua rau nws 100% tiv thaiv electromagnetic cuam tshuam (EMI) thiab hauv av-loop hum feem ntau nrog kev sib txuas hluav taws xob.
Keeb kwm qhia los ntawm Toshiba hauv xyoo 1983 los txuas cov CD player rau cov neeg txais, TOSLINK tus qauv tau dhau los ua qhov mus rau kev sib txuas cov neeg siv khoom siv suab. Sij hawm dhau mus, daim foos hloov pauv mus rau Mini-TOSLINK (3.5 hli ntsaws rau lub laptops thiab cov khoom siv nqa tau yooj yim) thiab cov khoom siv hluav taws xob qis (POF) hloov pauv rau cov kev siv nyiaj txiag thiab kev siv luv luv.
