Muaj ntau hom fiber ntau optical, uas tuaj yeem muab faib ua ntau txoj hauv kev. Raws li lub sijhawm siv, nws tuaj yeem muab faib ua cov khoom siv kho qhov muag sab hauv tsev, sab nraum zoov kho qhov muag fiber ntau, ceg kho qhov muag fiber ntau, thiab faib cov khoom siv kho qhov muag; Raws li cov txheej txheem tso, nws tuaj yeem muab faib ua tus kheej- txhawb nqa nyiaj siv ua haujlwm kho qhov muag fiber ntau, cov kav dej kho qhov muag fiber ntau, armored faus optical fiber thiab submarine optical fiber; Raws li cov qauv kho qhov muag, nws tuaj yeem muab faib ua pob khoom Tubular optical fiber, stranded optical fiber, skeleton optical fiber, compact optical fiber, ribbon optical fiber, non-hlau fiber ntau optical fiber thiab branchable optical fiber; Raws li lub hom phiaj, nws tuaj yeem muab faib ua qhov ntev -qhov deb ntawm kev sib txuas lus kho qhov muag fiber ntau, luv-nruab nrab qhov chaw kho qhov muag fiber ntau, hybrid optical fiber ntau thiab lub tsev kho qhov muag sab hauv. Qhov twg los xaiv, thiab kev xaiv ntawm tus lej tseem ceeb thiab tus qauv yuav tsum tau txiav txim siab nyob rau hauv lub teeb ntawm qhov teeb meem tiag tiag.
Kev faib tawm tseem ceeb ntawm kev sib kis ntawm fiber ntau yog muab faib ua ib hom - hom thiab dual - hom los ntawm hom kis. Tib - hom optical fibers tau siv ntau hauv kev saib xyuas. Tib hom - hom fiber ntau tuaj yeem xa tawm ib hom kev teeb pom kev zoo xwb, thiab qhov kev ncua deb ntawm kev xa tawm 100M cov teeb liab tuaj yeem ncav cuag kaum ob mais. Tib hom - hom kho qhov muag fiber ntau kis raws cov tub ntxhais ntawm cov khoom siv kho qhov muag, uas tuaj yeem zam qhov teeb meem ntawm kev sib kis ntau dhau los ntawm kev sib faib hom. Feem ntau haum rau qhov loj -muaj peev xwm, ntev-qhov deb ntawm optical fiber kev sib txuas lus daim ntaub ntawv, lub optical wavelength yog 1310nm los yog 1550nm.
Multimode fiber can transmit multiple modes of optical signals, which are subdivided into OM1, OM2, and OM3 according to the mode. Multimode fiber can transmit 100M signals at the farthest distance of 2 kilometers. Due to dispersion or aberration, the transmission performance of this kind of optical fiber is poor, the frequency band is relatively narrow, the transmission capacity is relatively small, and the distance is relatively short.
