Qhov tseem ceeb ntawm cov yas optical fiber ntau

Lub wavelength:Kev sib kis wavelengths rau cov yas kho qhov muag fiber ntau (POF) yog 650 nm (lub teeb liab) thiab 850 nm, tab sis qee qhov kev ua tau zoo ntawm cov yas kho qhov muag fibers kuj txhawb cov wavelengths ntev (xws li 1300 nm).

Attenuation:Xa mus rau qhov kev poob qis thaum lub teeb liab optical kis tau los ntawm fiber ntau, feem ntau qhia hauv dB / km.

Kis tus nqi:Rau kev ncua deb, cov yas kho qhov muag fiber ntau tuaj yeem pab txhawb kev sib kis tau zoo. Tsis pub dhau 100 meters, yas optical fiber tuaj yeem xa cov ntaub ntawv ntawm qhov nrawm txog li 1 Gbps.

Core Diameter:Cov tub ntxhais diameters feem ntau rau cov yas kho qhov muag fiber ntau yog li ntawm 0.25 hli mus rau 3 hli, loj dua li cov iav fibers (feem ntau yog 8 txog 62.5 micrometers). Cov tub ntxhais loj dua ua rau cov yas kho qhov muag pom kev yooj yim dua los txuas thiab tuav.

Numerical Aperture (NA):Tus lej aperture yog nyob ib ncig ntawm {{0}}.5, lub ntsiab lus yas kho qhov muag fiber ntau muaj lub kaum ntse ntse txaus, ua kom yooj yim rau ob peb lub teeb pom kev zoo. Tsis tas li ntawd, muaj cov fibers tshwj xeeb nrog tus lej aperture ntawm 0.48 lossis 0.6.

Khoov Radius:Yas kho qhov muag fibers muaj zoo heev dabtsi yog khoov kev ua tau zoo, tso cai rau me me khoov radii, feem ntau nyob ib ncig ntawm 10 npaug ntawm cov tub ntxhais txoj kab uas hla. Lawv yog cov resistant rau dabtsi yog khoov dua iav fibers.

Qhov kub thiab txias:Kev khiav hauj lwm kub ntau rau cov yas kho qhov muag fibers feem ntau yog nyob nruab nrab ntawm -40 degree thiab +85 degree, tab sis qee qhov tshwj xeeb yas kho qhov muag fibers tuaj yeem tiv taus kub txog 105 degree . Kuj tseem muaj cov ntaub ntawv tshwj xeeb sab nrauv muaj rau siv nyob rau hauv qhov chaw kub kub.

Mechanical Strength:Yas optical fibers muaj zog dua toughness thiab tensile zog piv rau iav fibers thiab muaj ntau yam-resistant.
