Tsis tas li ntawd, qhov kev ncua deb ntawm ib hom fiber ntau yog dab tsi?

Thaum ua haujlwm nrog nyob deb mus txog 2 km, siv multimode kho qhov muag - fiber ntau kab. Singlemode optical - fiber ntau cable, txawm li cas los xij, muaj ntau bandwidth-intensive thiab muaj peev xwm tsawg dua rau modal dispersion thiab suab nrov dua li multimode kho qhov muag - fiber ntau cable, txhais mus rau lub peev xwm kis tau tus mob tshaj lub nyob deb kev txwv ntawm multimode.

Tsis tas li ntawd, qhov tsawg kawg nkaus nyob deb li cas rau ib hom fiber ntau? Cov ntaub ntawv "Cisco SFP Modules rau Gigabit Ethernet Applications Data Sheet" hais tias yam tsawg kawg nkaus kab nyob deb rau tag nrho SFPs teev (multimode thiab ib leeg - hom fiber ntau ) yog 6.5 feet (2 m).

Kuj Paub, qhov twg yog qhov ntev tshaj plaws fiber optic cable?

Cov ntev tshaj plaws un-regenerated terrestrial fiber ntau optic qhov txuas yog 10, 358.16 km (6, 436.26 mi) thiab tau ua tiav los ntawm Telstra Corporation (Australia) nrog lawv qhov txuas ntawm Perth thiab Melbourne, Australia, raws li tau txheeb xyuas thaum Lub Ob Hlis 13, 2015.

Koj tuaj yeem khiav fiber ntau ntev npaum li cas?

Niaj hnub fiber ntau cov kab mob optic ua tau nqa lub teeb liab mus deb heev - tej zaum 60 mais (100 km). On ib ntev kab nrug, nyob ntawd yog ib lub tsev pheeb suab khoom txhua txhua 40 mus rau 60 mais.
