1. Kev sib txuas lus zoo heev
Raws li kev xav, ib qho fiber ntau tuaj yeem xa 10 billion lub suab hauv tib lub sijhawm tam sim no, qhov kev sim ntawm kev xa tawm 500,000 lub suab raws tib lub sijhawm tau ua tiav, ntau txhiab lossis ntau pua txhiab zaus ntau dua li cov xov tooj cua thiab microwaves . .
2. Ntev ntev relay
Optical fiber ntau attenuation coefficient tsawg heev, thiab nrog kev sib kis tau zoo, kho qhov muag txais khoom, kho qhov muag amplifier, kev kho qhov yuam kev thiab RZ coding modulation tshuab, thiab lwm yam, nws tuaj yeem ua rau qhov nrug ntawm koj relay mus txog ntau tshaj li txhiab kilometers, thaum. Cov kab hluav taws xob ib txwm tuaj yeem kis tau 1.5 km, microwave 50 km, tsis tuaj yeem muab piv rau txhua qhov.
3. Kev ceev ntiag tug zoo
4. Muaj zog adaptability
Nws muaj qhov zoo ntawm kev tsis ntshai cuam tshuam los ntawm kev muaj zog sab nraud electromagnetic teb, corrosion kuj, thiab lwm yam.
5. Me me thiab lub teeb yuag.
6. Ntau qhov chaw ntawm cov khoom siv raw thiab cov nqi qis
