Hi all,
I am not so sure if TM really can give 10x speed upgrade right now.
As I understand it, GPON is shared bandwidth. Meaning the 2.5Gbps down / 1.25Gbps up is per port on the OLT. If there are 32 ONU connected to the one OLT port, all 32 ONU will share the 2.5Gbps down / 1.25Gbps up.
Furthermore, GPON is TDM based so each ONU is allocated a fixed transmit / receive time slot. Eg: If everyone on the OLT port is upgraded to 300mbps, the splitter for that port can only connect a maximum of 8 ONU (I am not factoring IPTV / VOIP / TR069 yet)
In my understanding, to mass upgrade everyone to turbo speed, TM need to rollout NG-PON2. Since the wavelength of GPON and NG-PON2 is different (meaning they can co-exist but not compatible), TM need to give everyone a new ONU, regardless of your ONU has gigabit port or not
I really don't think TM will buy more OLT and convert their PtMP PON infrastructure into a PtP PON
Not everyone in the same OLT port will use max 800Mbps etc sustained on a daily basis.
