Today, I will explain the basic procedure for the installation combo board.
I have dedicated several articles on migrating from GPON to XG(S)-PON standard. Then they show the process of installing the combo board and the basic configuration.
For this purpose, I use OLT MA5800-X7 and combo board H903CGHD. OLT MA5800-X7 has GPON service boards H902GPHF in slots 1 and 3.
Combo board H903CGHD support GPON and XG-PON standards. This board has 8 slots for SFP optical modules. WDM module is integrated into every SFP optical module. In the next figure, we can see this type of combo board.
Figure 1. Combo board – H903CGHD
After installing the combo board in slot 6 OLT MA5800-X7, we get the following information on OLT:
TEST(config)#
1 [22-11-2021 20:38:13+08:00]:
Auto find a board,FrameID:0,SlotID:6,Board_name:H903CGHD
The next command shows all boards in the OLT:
TEST(config)#display board 0
{ <cr>||<K> }:
Command:
display board 0
-------------------------------------------------------------------------
SlotID BoardName Status SubType0 SubType1 Online/Offline

8 H903MPLA Active_normal
9 H903MPLA Standby_normal
10 H902PILA Normal
11 H902PILA Normal
-------------------------------------------------------------------------
After that, we have to confirm the combo board. We can do it, with the next command:
TEST(config)#board confirm 0/6
0 frame 6 slot board confirms successfully
We can use the command #board confirm, too. After that, we can see the current configuration of the combo board. For this action, we use the next commands:
TEST(config)#interface gpon 0/6
TEST(config-if-gpon-0/6)#display this
{ <cr>|include-default<K>||<K> }:
Command:
display this
[gpon]
<gpon-0/6>
interface gpon 0/6
port combo-mode 0 wdm
port combo-mode 1 wdm
port combo-mode 2 wdm
port combo-mode 3 wdm
port combo-mode 4 wdm
port combo-mode 5 wdm
port combo-mode 6 wdm
port combo-mode 7 wdm
#
return
Then, we have to configuration every PON port – FEC, ONT auto-find and DBA. For this basic configuration, we will use the next commands:
TEST(config-if-gpon-0/6)#port 0 fec enable
TEST(config-if-gpon-0/6)#port 0 ont-auto-find enable
TEST(config-if-gpon-0/6)#port dba bandwidth-assignment-mode 0 max-bandwidth-usage
…
After finishing this configuration, we can see the current configuration of the combo board. The next command shows the current configuration of the combo board:
TEST(config-if-gpon-0/6)#display this
{ <cr>|include-default<K>||<K> }:
Command:
display this
[gpon]
<gpon-0/6>
interface gpon 0/6
port 0 ont-auto-find enable
port 0 fec enable
port dba bandwidth-assignment-mode 0 max-bandwidth-usage
port combo-mode 0 wdm
port 1 ont-auto-find enable
port 1 fec enable
port dba bandwidth-assignment-mode 1 max-bandwidth-usage
port combo-mode 1 wdm
port 2 ont-auto-find enable
port 2 fec enable
port dba bandwidth-assignment-mode 2 max-bandwidth-usage
port combo-mode 2 wdm
port 3 ont-auto-find enable
port 3 fec enable
port dba bandwidth-assignment-mode 3 max-bandwidth-usage
port combo-mode 3 wdm
port 4 ont-auto-find enable
port 4 fec enable
port dba bandwidth-assignment-mode 4 max-bandwidth-usage
port combo-mode 4 wdm
port 5 ont-auto-find enable
port 5 fec enable
port dba bandwidth-assignment-mode 5 max-bandwidth-usage
port combo-mode 5 wdm
port 6 ont-auto-find enable
port 6 fec enable
port dba bandwidth-assignment-mode 6 max-bandwidth-usage
port combo-mode 6 wdm
port 7 ont-auto-find enable
port 7 fec enable
port dba bandwidth-assignment-mode 7 max-bandwidth-usage
port combo-mode 7 wdm

On the PON port 0, I connected two GPON ONTs: HG8247H5 (Gateway ONT: 1GE port, 3 FE ports, 1 POTS port and 1 RF port) and HG8012H (Bridge ONT: 1 GE port and 1 RF port). With the next command, we can see information about these ONTs on the port:
TEST(config-if-gpon-0/6)#display ont autofind 0
{ <cr>||<K> }:
Command:
display ont autofind 0

This is the end of this topic. As we can see in this topic, the basic configuration of the combo board is the same as the basic configuration of the GPON service board. With this combo board, GPON works without problems, everything worked without any problems. Also, on this PON port, I connected 10G ONT - HN8546Q and everything worked without any problems. To test speeds over 1 Gbps, use multiple PCs, some server or router e.g. mikrotik, etc.
I hope you learned something new!
Thank you!
