This has always puzzled me. If this is the case, all the current ISP 2Gbps/ dual 1Gbps plans will have the uplink speed capped at 1.244Gbps across the 4 ONR ports (SingTel 2Gbps or Viewquest 2Gbps) or the two 1Gbps line (Starhub 2Gbps, MyRepublic 1+1, or SingTel 1+1).
Yes. Because there's only 1 GPON connection back to their OLT, you're hard capped by the limits of that 1 GPON connection. Of course it's not to their benefit that they advertise this as prominantly as 1+1Gbps, so most consumer won't know. It could be in the fine prints, but I haven't went about looking for it.
On the other hand, only MyRepublic is saying that uplink speed is limited to 500Mbps for its 1Gbps plan and that applies its 1+1 Gbps plan.
Then they are limiting the uplink speed for those plans, nothing to do with hitting the theoretical limits of a single GPON connection.
SingTel only says its 10Gbps plan is not symmetrical because of the use of XG-PON (downlink 10Gbps, uplink 2.5Gbps) and not XGS-PON.

I guess in their expected use case of the 1+1Gbps plan, they did not expected users to aggregate both WAN conenctions together. If the users don't aggregate the WAN connections, they will never hit above 1Gbps down and up at any one time. If the user aren't going to be hitting the hard limits of that GPON connection, I guess it's in their best interest to not talk about it to avoid "unnecessary questions" for their helpdesk/sales team?
Whereas for their 10Gbps plan, it is likely that the user have a 10GbE NIC. In that case the user would very quickly realise they are hitting the limits of SingTel's implementation of XG-PON, so I guess it's better for them to be upfront that their the XG-PON tech they implemented has an uplink limit of 2.5Gbps.
Do note I'm just speculating here, don't take it as facts.
