I am updating to a 4 Port OLT, which is why I am selling this one. It is fresh and you can check it before buying.
PON Port Speed (Uplink/Downlink):
The maximum transmission rate or speed of each EPON port is 1.25 Gbps (Symmetric). That means it can deliver up to 1.25 Gbps speed in both downlink and uplink. [1, 2]
GE Uplink Port Speed: The maximum speed of each of the 6 Gigabit Ethernet (GE) ports on the OLT is 1 Gbps (1000 Mbps). [1, 2]
Backplane Bandwidth (Switching Capacity): The internal data processing or backplane throughput of this OLT is up to 32 Gbps (P3310C model) and 20 Gbps (P3310D model).
