1. Muaj peev xwm sib txuas lus zoo heev
Hauv kev xav, ib lub fiber ntau tuaj yeem xa 10 billion lub suab tib lub sijhawm. Tam sim no, kev sim xa 500,000 lub suab tib lub sijhawm tau ua tiav - ntau txhiab lossis ntau pua txhiab zaus ntau dua li cov xov tooj cua coaxial thiab microwaves.
2. Kev xa xov ntev
Cov fiber ntau optical muaj qhov coefficient attenuation qis heev, thiab nrog kev xa hluav taws xob zoo, cov khoom siv txais hluav taws xob, lub zog amplifier optical, kev kho qhov yuam kev pem hauv ntej, thiab RZ coding modulation technology, thiab lwm yam, nws tuaj yeem ua rau qhov deb ntawm koj lub relay ncav cuag ntau dua ntau txhiab kilometers, thaum cov cables ib txwm tsuas tuaj yeem xa 1.5 km, microwaves 50 km, nws tsis tuaj yeem piv rau txhua.
3. Kev ceev ntiag tug zoo
4. Muaj kev hloov pauv tau zoo
Nws muaj qhov zoo ntawm kev tsis ntshai kev cuam tshuam los ntawm cov teb hluav taws xob sab nraud muaj zog, kev tiv thaiv corrosion, thiab lwm yam.
5. Me me thiab lub teeb yuag.
6. Muaj ntau yam khoom siv raw thiab tus nqi qis
