Backbone optical kev sib txuas lus system muaj peev xwm

 

Lub cev muaj peev xwm xam tus qauv rau qhov ntev - nrugkab kab:

 

 

Ib qho 2.5G DWDM system nrog 160 channel tuaj yeem ua tiav tus nqi sib kis ntawm 400Gb / s.

Ib yam li ntawd, 320 channel tuaj yeem ua tiav qhov kev sib kis ntawm 800Gb / s.

Lub 40G system nrog 320 channel yuav muaj peev xwm ntawm 12.8 Tb / s.

 

n kis tau tus mob qauv nrog n- ntu amplifier txuas:

 

Ntev -nqe qaum qaum lossis submarine cable kis tau tus mob feem ntau yuav tsum tau rov ua dua.

Cov teeb liab kho qhov muag -rau- suab nrov piv piv piv rau kev sib kis:

 

Cov nkhaus rau tus naj npawb ntawm cov channel thiab lub zog kho qhov muag sib txawv nyob ntawm qhov kev ncua deb ntawm relay, uas muaj qhov sib npaug ntawm cov teebmeem nonlinear thiab cov nqi amplifier.

 

 

Kev ncua ntev dua yuav tsum muaj tsawg dua amplifiers, txuag nyiaj.

High tso zis optical zog yuav tsum tau, tab sis cov teebmeem nonlinear muaj.

Kev ncua sij hawm luv luv kom tsis txhob muaj qhov cuam tshuam tsis zoo, tab sis tus lej ntawm cov channel nce, ua rau cov nqi siab dua.
