Question

Which ports should be active on an Optical Network Termination?

a) Tx
b) Rx
c) Both Tx and Rx
d) Neither Tx nor Rx

Answer 1

The ports that should be active on an Optical Network Termination (ONT) are both Tx and Rx.

Step-by-step explanation:

The ports that should be active on an Optical Network Termination (ONT) are both Tx and Rx. The Tx port is used for transmitting data from the service provider to the customer, while the Rx port is used for receiving data from the customer back to the service provider. Both ports need to be active for bidirectional communication to occur. In a typical fiber-optic communication setup, data is transmitted from the service provider to the subscriber's premises (downstream) and from the subscriber to the service provider (upstream). Therefore, both Tx and Rx ports need to be active for bidirectional communication.
