Hello everyone!
Today, I will share with you basic information about GPON service boards.
Service boards are boards that enable the connection of OLT and ONUs. There are many different types of boards with multiple ports. In case of a problem with one of the boards, another one can be used.
In the next table, we can see all types of service boards.
Service board | Board Name |
GPON | GPHF(E), GPSF |
10G GPON | XSHF(E), XSHD |
TDM | EDSH |
P2P | OGHK |
Ethernet | OXHD |
Fig. 1. GPON service board – H901GPHF
There are two hardware types of GPON service boards: GPHF(E) and GPSF. In the next table, we can see the main features of GPON boards H901GPHF and H901GPSF. There are small differences between these boards, which are shown in red in the next table.
