What term describes the signals traveling from the customer premise to the fiber node?

The term that describes the signals traveling from the customer premise to the fiber node is "upstream." In a typical broadband network configuration, there are two primary directions for signal flow: upstream and downstream.

Upstream refers to the data transmitted from the end user's equipment, such as a modem or router, back to the service provider's network, specifically towards a fiber node. This path is essential for activities such as sending emails or uploading files. In contrast, downstream describes the signals sent from the service provider to the customer premise, such as when downloading data or streaming video.

Understanding the distinction between upstream and downstream is crucial for broadband technicians, as it informs how signals are managed and optimized for various customer activities. This knowledge ensures that the network's performance meets user expectations and maintains reliability.
