Nkag siab lub wavelengths ntawm 850nm, 1310nm thiab 1550nm hauv optical fiber
Lub teeb yog txhais los ntawm nws lub wavelength, thiab nyob rau hauv fiber optic kev sib txuas lus, lub teeb siv yog nyob rau hauv lub infrared cheeb tsam, qhov twg lub wavelength ntawm lub teeb yog ntau tshaj qhov pom lub teeb. Hauv kev sib txuas lus fiber ntau optical, cov wavelength raug yog 800 txog 1600nm, thiab feem ntau siv wavelengths yog 850nm, 1310nm thiab 1550nm.
Duab qhov chaw:
Thaum fluxlight xaiv qhov sib kis wavelength, nws feem ntau txiav txim siab fiber ntau poob thiab tawg. Lub hom phiaj yog xa cov ntaub ntawv feem ntau nrog qhov tsawg kawg ntawm fiber ntau poob ntawm qhov ntev tshaj plaws. Qhov poob ntawm lub teeb liab lub zog thaum kis tau tus mob yog attenuation. Lub attenuation muaj feem xyuam rau qhov ntev ntawm lub waveform, qhov ntev waveform, qhov me me ntawm attenuation. Lub teeb siv nyob rau hauv fiber ntau muaj ib tug ntev wavelength ntawm 850, 1310, 1550nm, yog li ntawd lub attenuation ntawm fiber ntau yog tsawg, uas kuj ua rau cov fiber ntau poob. Thiab peb lub wavelengths no yuav luag xoom nqus, uas yog qhov tsim nyog tshaj plaws rau kev xa mus rau hauv cov khoom siv kho qhov muag raws li muaj cov teeb pom kev zoo.
Duab qhov chaw:
Hauv kev sib txuas lus fiber ntau optical, optical fiber ntau tuaj yeem muab faib ua ib hom thiab ntau hom. Lub cheeb tsam 850nm wavelength feem ntau yog ntau hom kev sib txuas lus fiber ntau, 1550nm yog ib hom, thiab 1310nm muaj ob hom tib hom thiab ntau hom. Xa mus rau ITU-T, qhov attenuation ntawm 1310nm yog pom zoo kom ≤0.4dB/km, thiab attenuation ntawm 1550nm yog ≤0.3dB/km. Thiab qhov poob ntawm 850nm yog 2.5dB / km. Fiber poob feem ntau txo qis thaum lub wavelength nce. Qhov nruab nrab wavelength ntawm 1550 nm nyob ib ncig ntawm C-band (1525-1565nm) feem ntau yog hu ua xoom poob qhov rais, uas txhais tau hais tias qhov attenuation ntawm quartz fiber yog qhov tsawg tshaj plaws ntawm qhov wavelength no.
Beijing Rofea Optoelectronics Co., Ltd. nyob rau hauv Tuam Tshoj lub "Silicon Valley" - Beijing Zhongguancun, yog ib tug high-tech enterprise mob siab rau ua hauj lwm nyob rau hauv lub domestic thiab txawv teb chaws kev tshawb fawb cov koom haum, kev tshawb fawb institutes, universities thiab enterprise scientific kev tshawb fawb neeg ua hauj lwm. Peb lub tuam txhab feem ntau yog koom nrog kev tshawb fawb ywj pheej thiab kev tsim kho, tsim, tsim khoom, muag khoom ntawm optoelectronic cov khoom, thiab muab cov kev daws teeb meem tshiab thiab kev tshaj lij, kev pabcuam tus kheej rau cov kws tshawb fawb tshawb fawb thiab cov kws tshaj lij. Tom qab xyoo ntawm kev ywj pheej innovation, nws tau tsim ib tug nplua nuj thiab zoo meej series ntawm photoelectric khoom, uas yog dav siv nyob rau hauv lub nroog, tub rog, tsheb thauj mus los, hluav taws xob fais fab, nyiaj txiag, kev kawm, kev kho mob thiab lwm yam lag luam.
