Yog lawm, Fiber Optic Optic Internet tau nrawm dua li kev coj ua cable cable hauv cov nqe lus ntawm Raw Ceev, Latency, thiab ntseeg tau. Ntawm no yog qhov sib piv:
1. Ceev
Fiber Optic:
Tuaj yeem xa nrawm nce mus txog 10 gbps (qee tus muab kev pabcuam muaj ntau dua nyob rau qee thaj chaw).
Saimetrical Kev nrawm (upload thiab rub tawm nrawm yog tib yam).
Cable (Coaxial):
Feem ntau muaj kev nrawm txog 1-2 gbps (tab sis feem ntau qis dua hauv kev xyaum).
Asymmetrical ceev (upload ceev ceev yog qhov qeeb qeeb tshaj rub tawm, feem ntau 5-10x qeeb qeeb).
2. Latency (lub sijhawm teb)
Fiber:
Ntau qis qis (feem ntau<10 ms) because light travels faster than electrical signals.
Zoo dua rau kev twv txiaj, hu nkauj video, thiab cov ntawv thov realtime.
Cable:
Siab dua latency (feem ntau 15-50 ms), uas tuaj yeem cuam tshuam kev twv txiaj online thiab video sib tham.
3. Kev ntseeg tau & xwm txheej
Fiber:
Tsis cuam tshuam los ntawm kev cuam tshuam hluav taws xob hluav taws xob (vim nws siv lub teeb).
Ntau ruaj khov thaum lub sij hawm siv sijhawm (tsis muaj teeb meem bandwidth).
Cable:
Siv cov xov tooj ntiav, uas tuaj yeem raug kev txom nyem los ntawm kev cuam tshuam thiab teeb liab kev teeb meem.
Kev nrawm yuav poob thaum lub sijhawm siab tshaj plaws (sib koom bandwidth hauv cov zej zog).
4. Kev txhawb nqa yav tom ntej
Fiber ntau tuaj yeem ua rau yav tom ntej bandwidth xav tau (zoo li 8k streaming, vr, thiab iot).
Cable nyob ze nws qhov kev txwv thev naus laus zis thiab yuav tawm tsam nrog kev hloov khoom tshiab yav tom ntej.
Tag
Fiber si yog sai dua, ntau txhim khu kev qha, thiab qis dua latency tshaj cable. Txawm li cas los xij, kev muaj yog qhov kev txwv tseem ceeb ntawm-fiber tsis yog siv dav dav siv raws li cable hauv qee thaj chaw. Yog tias koj muaj kev xaiv, fiber yog qhov kev xaiv zoo tshaj plaws rau kev nrawm thiab kev ua tau zoo.
