Tshaj Tawm Ib Yam Tshiab Ntawm Cov Txuas Txuas Raws Li Dual-core Optical Cable
Lub hom phiaj tseem ceeb ntawm cov khoom siv hluav taws xob txuas yog kom paub txog kev sib txuas fiber ntau. Cov kws tshawb nrhiav tau thov hom tshiab ntawm cov khoom sib txuas raws li dual-core fiber. Txuas lub axisymmetric tsis-coaxial ntxaib-ntxhais fiber ntau (TCF) mus rau asymmetric ntxaib-ntxhais fiber ntau (DPCF) qhov twg cov theem ua haujlwm ntawm ob khub ntawm lub cores tsis sib xws, thiab DPCF thiab cov ntxaib-ntxhais fiber nyob qhov kawg yog txuas rau ob leeg-tub ntxhais fibers feem. Hom fiber ntau qhov txuas. Tus kho qhov muag hluav taws xob no tau txais daim ntawv thov tau zoo vim yog cov yam ntxwv ntawm poob qis thiab lub teeb liab tawg.
optical fiber amplifier
Lub erbium-doped fiber amplifier raws li dual-core fiber ntau tuaj yeem muab cov kab hluav taws xob ua kom sib luag, tsis quav ntsej qhov poob ntawm qhov hloov pauv ntawm cov amplifiers thiab cov hla kev hla teeb ntawm lub teeb liab. Cov cuab yeej siv dav rau qhov sib cais sib faib ua ke ntawm cov channel thiab cov saturation yam ntxwv ntawm erbium ions thiab lub zog. Hauv dual-core erbium-doped fiber ntau qhov sib npaug amplifier, ob qhov xaum yog Er3 + doped. Cov kws tshawb nrhiav tau npaj siab ua dual-core erbium-doped fiber ntau lub zog txuas nrog kev nce tiaj tus. Cov suab nrov no tuaj yeem ua tiav cov zis hluav taws xob sib npaug rau qee yam, uas haum rau qhov yuav tsum tau ua ntawm ntau cov channel ntau-theem ua kom pom tseeb thiab nthwv dej faib rau kev faib cov cuab yeej hluav taws xob fiber ntau kho qhov muag thiab cov kev sib txuas hauv kev txhim kho kev sib txuas lus yav tom ntej.
Lub luag haujlwm ntawm tus kho qhov muag ntxiv / tso multiplexer yog kom muab tso thiab rub tawm cov teeb liab nkees, thiab yog ib qho tseem ceeb ntawm cov kab rov tav ntev hauv network thiab cov chaw hauv nroog. Cov kws tshawb nrhiav tau hais tawm ib qho ntxiv / tso cov multiplexer raws li dual-ntxhais fiber. Tom qab sau ntawv fiber ntau ntawm qhov sib luag ntev ntawm ob lub cores, cov tswv yim teeb pom kev sib txawv ntawm lub yoj yoj sib txawv los ntawm A1 kawg, thiab lub teeb nkag mus rau hauv qhov chaw grating tom qab kev sib nrig sib txuas hauv thaj chaw tsis-grating, thiab siv Bragg grating kom pom tseeb lub teeb liab kho qhov muag ntawm ib qho kev yob ntev los ntawm B1 kawg Tsim Tawm, thaum cov cim txuas ntxiv txuas mus ntxiv mus rau tom ntej, thiaj li ua tiav qhov ua haujlwm ntawm daus teeb liab. Ib yam li ntawd, cov tswv yim hauv qhov rov qab tuaj yeem pom lub teeb liab upload function.
