Maybe this can be helpful for someone who also contracted the 2 Gbps plan. I did lots of searching on Internet and found a very affordable solution. The cost is less than 30 SGD.
I recently subscribed to Singtel's 2Gbps Enhanced plan because the price difference between 1 Gbps and 2 Gbps for new user is marginal. However, the Ethernet ports on the installed ONR by Singtel only support 1 Gbps speed. In order to fully utilize the 2 Gbps speed, you need to change the ONR from Singtel.
I purchased a VSOL V2802RH ONT from Taobao (only costs ~150 RMB, or ~28 SGD) with 1*2.5 Gb + 1* 1 Gb Ethernet ports. (

I use the Bridge mode for this ONT. You can also configure this ONT as a router, then you need to use IPoE in Channel Mode as described below. You should do the setup below without plugging in your fiber, because the ISP will push some settings to your ONT after you plug in your fiber. Therefore, you should only plug in your fiber after you complete the setup.
1. Under Setup | WAN | GPON Settings, mirror your LOID, LOID Password, PLOAM Password from your ONR. For Singtel, you just need to set PLOAM Password as your Fibre ID, and LOID, LOID password you can put anything like
123456789 and
123456.
2. Open the telnet port under Firewall | ACL, then use telnet login to the ONT and then write the GPON_SN of your old ONR to this ONT. You can find relevant information on the Internet. One of the examples is:
https://www.odbook.com/1215.html (in Chinese) I think GPON_SN and PLOAM Password are used for PON authentication by Singtel.
3. Under Setup | WAN | WAN Settings, add a new WAN interface by clicking "Add" with following settings:
Default Route Selection -> Specified
Channel Mode -> Bridge <- if you use this ONT as a router, you should set this to IPoE
Enable IGMP -> checked
VLAN -> Enable
VLAN ID -> 10 <- type 10, here if you see VLAN ID = 10 is reserved, don't forget the comma
VLAN Cos -> 0
Multicast VLAN ID -> 0
Application Mode -> INTERNET
Request DNS -> Enable
Default Route -> Enable <- I found it always goes back to "Disable" automatically
LAN -> tick LAN2 <- LAN2 is the 2.5 Gb port
4. Under Setup | LAN | DHCP, set DHCP Mode to None. <- If you use this ONT as a router, you should leave this on
If everything goes well, you will see "Registered,Certificated" under Status | Device Info | PON | Connect state, and "O5" under Status | Device Info | PON | ONU status. Then you can configure the IP of your router or computer using DHCP to get IP address and DNS Servers automatically.
Now you can see the download speed is over 2 Gbps:

However, I found the upload speed is still 1 Gbps. Maybe this is limited by the ISP.
