Itsinda ry'abashakashatsi bo mu kigo cy'ubushakashatsi cy'ikigo cy'igihugu gishinzwe ikoranabuhanga mu itumanaho (NICT, mu Buyapani) bageze ku gahigo gashya ku isi mu gukoresha uburyo bwa interineti mu buryo bumwe. fibre optique y'umurambararo usanzwe.
Abashakashatsi bagezeho bandwidth ya petabits zigera kuri 1.53 kuri segonda binyuze mu kwandika amakuru mu miyoboro 55 itandukanye y'urumuri (uburyo buzwi nka multiplexing). Iyo bandwidth ihagije kugira ngo itware abantu bose basura interineti ku isi (igereranyijwe munsi ya petabit 1 kuri segonda) binyuze mu mugozi umwe wa fiber optique. Ibyo bitandukanye cyane n'imiyoboro ya gigabit abantu basanzwe bashobora kubona (mu bihe byiza): mu by'ukuri, ni inshuro miliyoni nyinshi.
Iri koranabuhanga rikora binyuze mu gukoresha imirongo itandukanye y'urumuri iboneka kuri spectrum. Kubera ko buri "bara" riri muri spectrum (y'urumuri rugaragara n'urutagaragara) rifite umurongo waryo wihariye, utandukanye n'ayandi yose, rishobora gukorwa kugira ngo ritware amakuru yaryo yigenga. Abashakashatsi bagezeho ubushobozi bwa spectral bwa 332 bits/s/Hz (bits kuri segonda kuri Hz). Ibyo bikubye gatatu imikorere myiza kurusha uko bagerageje mbere, mu 2019, aho bagezeho ubushobozi bwa spectral bwa 105 bits/s/Hz.
