Basic Structure Ntawm Fiber Optic Cable

Nws feem ntau muaj peb ntu: fiber ntau core, cladding, thiab sheath. Cov tub ntxhais fiber ntau yog cov channel tseem ceeb rau kev xa xov hluav taws xob kho qhov muag, cladding tiv thaiv cov tub ntxhais fiber ntau thiab ua kom tag nrho cov kev xav hauv nruab nrab ntawm cov teeb liab kho qhov muag nyob rau hauv cov tub ntxhais fiber ntau, thiab cov sheath tiv thaiv tag nrho cov qauv fiber ntau los ntawm kev puas tsuaj los ntawm ib puag ncig sab nraud.

 

Core: Lub hauv paus, kwv yees li 5-10 micrometers inch (txog lub thickness ntawm tib neeg cov plaub hau), ua los ntawm high-purity iav los yog yas, qhov twg optical signals kis tau tus mob.

 

Cladding: Ib txheej uas nyob ib puag ncig lub hauv paus, nrog qhov qis qis dua qhov ntsuas qhov tseem ceeb, kom ntseeg tau tias lub teeb nthuav dav hauv cov tub ntxhais los ntawm tag nrho cov kev xav sab hauv.

 

Txheej: Cov khoom siv tiv thaiv sab nrauv (xws li yas lossis hlau), muab lub zog tensile, tiv thaiv ya raws, thiab tiv thaiv corrosion.
