Configuring the CATV Service on OLT EA5801
The OLT EA5801-GP08 is connected to the remote ONT through a GPON port to provide users with the CATV service.
Prerequisites
- The ONT is added to the OLT.
- The ONT supports the CATV function.
Context
The optical transmitter at the CO end converts CATV signals to 1550 nm optical signals. After being amplified by the built-in optical amplifier inside the EDFA integrated device, the built-in WDM1r module multiplexes the 1550 nm optical signals and data optical signals for transmission. The CATV receiver on the user side or the ONT supporting CATV reception then restore 1550 nm optical signals to CATV video signals, as shown in the following figure.
NOTE: As shown in the figure, the EDFA is an integrated device supporting amplifying and multiplexing, which integrates optical amplifiers and WDM1r modules.
On the OLT side, enable ONT CATV (which is enabled by default). On the ONT side, no other configurations are required.
Procedure
- (Optional) Enable ONT CATV.The port is enabled by default.
