Flex-PON Solution | XG (S) – PON
Hello, everyone!
Today, I would like to share with you about the Flexible PON solution.
What’s Flex-PON?
Flex-PON is a solution developed by Huawei in order to implement smooth netwoork Evolution from GPON to XG(S) – PON. Unlike the XG (S) – PON COMBO card which can only operate in the GPON + XG-PON or GPON + XGS-PON scenarios, the Flex-PON card can work in multiple modes, including the modes found on the PON Combo card.
Supported work modules
- GPON
- XG-PON
- XGS-PON
- GPON&XG-PON Combo
- GPON&XGS-PON Combo

By default, the ports on this card work in GPON mode and can be used after insertion of a GPON optical module, without the need for license activation. To carry out the evolution from GPON to XG (S)-PON, it is necessary to activate an RTU license, optical module, and ONU/ONT compatible with the technology. Below mapping between, Port Mode, RTU, Optical Module, and ONU/ONT.
When formulating an evolution solution for the Flex-PON, ensure that the port mode is supported by the RTU, optical module, and ONU.

Evolution Process
After we understand what the Flex-PON solution is, let’s understand how the evolution process from GPON to XG-PON and GPON to XGS-PON works.
GPON to XG-PON
Figure 3 – Evolution process
1. Upload the RTU license to the OLT. This process must be done using the NCE-FAN management system. With this System, we will remotely activate the XG(S) PON RTU license for the Flex-PON port.
2. Access OLT and configure Flex-PON port mode from GPON to XG-PON.
Forum_MVE(config-if-gpon-0/1)#port flex-mode
{ all<K>|portid<U><0,15> }:0
{ combo-pon<K>|gpon<K>|xg-pon<K>|xgs-pon<K> }:xg-pon
3. Replace the GPON optical module with the XG-PON optical module.
4. Add the XG-PON ONU or replace the GPON ONU with the XG-PON ONU.
5. Configure the services and the evolution is complete.
GPON to XGS-PON
The process is similar to that done in the GPON to XG-PON method, what changes will be the command used in process 2. The command for evolution from GPON to XGS-PON is as follows:
Forum_MVE(config-if-gpon-0/1)#port flex-mode
{ all<K>|portid<U><0,15> }:0
{ combo-pon<K>|gpon<K>|xg-pon<K>|xgs-pon<K> }:xgs-pon
