The PON port is like the main gate on the ONU (Optical Network Unit), connecting it to the Optical Distribution Network (ODN). Cisco's Routed PON Solution is a transformational approach that condenses the OLT chassis into a pluggable form factor. It integrates the reception and conversion of fiber-optic signals, translating XGSPON or XGS-PON protocol signals into Ethernet. In short: The OLT (Optical Line Terminal) is the central control unit of a Passive Optical Network (PON). It comes with various ports to suit different needs. This article uses the FS ONU TA1910-4GVC-W as an example to explain these ports and their connections in detail.
