Ingabe i-GPON ishesha kune-FTTH?

Cha. I-GPON yi-FTTH. Yindlela ejwayelekile ye-GPON kanye nomklamo wenethiwekhi okunquma isivinini sakho, hhayi i-FTTH uqobo.

Yikuphi okuthembekile kakhulu: i-GPON noma i-FTTH?

Zombili zithembekile njengoba i-GPON iyindlela yokuletha i-FTTH. I-Fiber imane nje iwuxhumano oluhle olunezinzimo eziphakeme kanye nesikhathi esincane sokungasebenzi.

Ingabe kukhona umehluko wezindleko phakathi kwe-GPON nezinye ubuchwepheshe be-FTTH?

Yebo. I-GPON ivame ukonga kakhulu kubahlinzeki ngoba ivumela i-fiber ukuthi yabelwane phakathi kwababhalisile abaningi futhi igcina izindleko ziphansi.

I-GPON ikuthinta kanjani ukusebenza kwe-inthanethi?

I-GPON ubuchwepheshe bokufinyelela i-inthanethi obushesha kakhulu obusekela izinsizakalo eziningi (i-inthanethi, izwi, i-TV). I-bandwidth iyabiwa, ngakho-ke ayisebenzi kahle uma abantu abaningi bevuliwe ngesikhathi esisodwa.

Ingabe i-GPON "ilungele ngokwanele" izidingo ze-inthanethi zesikhathi esizayo?

Kwabaningi bemindeni kanye nama-SMB, i-GPON ikhonza lapha namanje kanye nezidingo zesikhathi esiseduze. Njengoba izidingo zedatha zanda, zingase zinqotshwe ubuchwepheshe obusha befayibha.

Ingabe ukuthuthukiswa kusuka ku-GPON kuya kolunye ubuchwepheshe be-FTTH kuzothuthukisa i-inthanethi yami?

Kuyahlukahluka. Uma umndeni wakho unabasebenzisi abaningi abadinga kakhulu noma abasebenzisa ngasikhathi sinye, ukuthuthukiswa kobuchwepheshe obusha njenge-XGS-PON kungaletha isivinini esikhulu kanye nokuzinza.
