5.20.1 Introduction
The 12-port 1000M EPON optical interface + 12-port 100M/1000M optical interface card (SFP)
is called E12GA. The E12GA provides 12 GE optical interfaces and 12 Gigabit Ethernet Passive
Optical Network (GEPON) interfaces.
5.20.2 Function and Application
Function Description
The E12GA provides 12 GE optical interfaces and 12 GEPON optical interfaces to implement
data access and wire-speed switching. Each GEPON interface can be connected to a maximum
of 64 optical network units (ONUs). The entire E12GA supports a maximum of 768 ONUs.
Application
The E12GA can be installed in any LPU slot of the S9312, S9306, and S9303. The S9300
installed with the E12GA can be used as the optical line terminal (OLT) to connect to the ONU
through an EPON interface.
5.20.3 Panel
Figure 5-32 shows the appearance of the E12GA panel.
The 12 interfaces on the left of the panel are the EPON optical interfaces and the 12 interfaces
on the right of the panel are the ordinary GE interfaces.
