Qhov zoo ntawm cov yas optical fiber ntau
Feem ntauPOF fiber ntauyog cov loj-core kauj ruam index multimode fibers, feem ntau 1 mm nyob rau hauv txoj kab uas hla. Qhov loj loj no ua rau nws yooj yim rau ob peb lub teeb loj ntawm lub teeb los ntawm lub teeb thiab cov khoom sib txuas yam tsis tas yuav tsum muaj qhov siab. Yog li ntawd, cov khoom txuas raug nqi 10-20 feem pua ntawm fiberglass, thiab lub davhlau ya nyob twg yuav yooj yim txiav nrog rab chais hniav nrog me me los yog tsis muaj polishing. Ua yas, nws kuj yog ruaj khov thiab yooj yim rau nruab yam tsis ntshai kev puas tsuaj.
Los ntawm qhov pom ntawm qhov muag pom, cov tsoos POF fibers muaj kev ua haujlwm qis dua li cov iav fibers - nrog kev txo qis dua thiab qis dua bandwidth. Nws poob ntawm 650 nm yog 0.15-0.2 dB/m, thiab nws cov bandwidth raug txwv los ntawm nws qhov loj NA thiab cov kauj ruam index profile. Txawm li cas los xij, nws yog qhov txaus los khiav cov kev sib txuas luv luv, xws li hauv cov cuab yeej lossis cov duab sib txuas hauv ib chav mus txog 50 meters. Nyob rau hauv cov tsheb, tau kawg, nws twb muaj ib tug foothold nrog nws tshiab MOST thiab Flexray tes hauj lwm.
Tab sis nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm POF thev naus laus zis, qis NA POF tuaj yeem muab ntau dua bandwidth, thaum GI-POF muab cov bandwidth ntau dua nrog tus nqi qis. Tus qauv tsim tam sim no ntawm GI-POF muab txog 2 Ghz bandwidth dhau qhov kev ncua deb ntawm 100 meters, tab sis cov teeb meem tsim khoom tau cuam tshuam nws txoj kev saws me nyuam. Nyob rau hauv xyoo tas los no, ib hom tshiab ntawm VCSEL yuav tsum ua tiav cov nqi qis heev, lub zog siab thiab siab ceev emission.
