DCM Dispersion Compensation Device
Huanet optical compensation function nrog slope dispersion compensation rau tus qauv ib hom fiber tuaj yeem DCM (G.652) yog dispersion thiab dispersion slope compensation broad band hauv C-band, uas tso cai rau lub kaw lus kom zoo dua qhov seem dispersion. Hauv qhov dispersion compensation tus nqi ntawm 1545nm wavelength dispersion tuaj yeem ncav cuag -2070ps / nm.
Cov DCM muaj qib kev them rov qab rau kev sib kis siab thiab qhov kev nplua rau kev poob qis heev. Lawv muab kev them rov qab rau kev sib kis tsis zoo thoob plaws C-Band tag nrho nrog rau qhov ntev ntev txog li 120 kilometers. Kev Ua Haujlwm DWDM system dispersion compensation thiab broadband qis residual dispersion Kev Them Nyiaj Rau Kev Tawg Tawm Thiab Kev Them Nyiaj Rau Kev Tawg Tawm Tau txais ntawm qhov kev them nyiaj rau qhov wavelength dispersion tshwj xeeb, yuav tsum ua kom tau raws li kev sib raug zoo hauv qab no: DTF × LTF + DDCF × LDCF = 0 DTF: kev sib kis fiber ntau; LTF: qhov ntev ntawm cov fiber kis tau tus mob; DDCF: kev tawg ntawm cov khoom siv fiber ntau uas ua rau cov khoom tawg; LDCF: qhov ntev ntawm cov fiber ntau dispersion; Kev them nyiaj rau qhov sib txawv ntawm qhov sib txawv hauv cov band, yuav tsum ua kom tau raws li kev sib raug zoo hauv qab no: STF × LTF + SDCF × LDCF = 0 STF: kev tawg ntawm cov fiber kis tau; SDCF: kev tawg ntawm cov khoom siv fiber ntau dispersion compensating Raws li ob txoj kev sib raug zoo saum toj no tau txais kev them nyiaj rau kev tawg thiab kev tawg kev them nyiaj, yuav tsum ua kom tau raws li qhov sib raug zoo hauv qab no: RDSDCF = SDCF / DDCF = STF / DTF Xav tias tus qauv ib hom fiber ntawm 1545nm wavelength dispersion ntawm 16.7ps / nm / km, qhov kev sib kis ntawm 0.060 ps / nm2 / km, RDS txog 0.0036nm﹣1.
