The Internet is a globally-connected network of computers that enables people to share information and communicate with each other. An intranet, on the other hand, is a local or restricted network that enables people to store, organize, and share information within an organization.

DWDM wavelength technology provides a high-capacity, cost-effective solution for long-distance communication. The use of multiple wavelengths on a single fiber allows for the transmission of a large amount of data over long distances, which is essential for applications such as internet backbone networks,

In a DWDM ring, the optical signals travel in both directions around the ring, with each node receiving and transmitting data to its adjacent nodes. The add/drop multiplexers allow nodes to add or drop data from the ring, which enables the network to support point-to-point, point-to-multipoint, and multipoint-to-multipoint communication.

A Fiber OLP system consists of two or more fiber paths between two locations, with one fiber path designated as the primary path and the other(s) as backup path(s). The primary path carries the live traffic, while the backup path(s) are kept idle and ready to take over in case the primary path fails.

The Fiber OLP system continuously monitors the primary path and automatically switches the traffic to the backup path if the primary path fails. This switch-over is done within milliseconds to ensure minimal disruption to the traffic flow.

In ASON, the network is designed to automatically detect and reroute traffic in case of network failures or congestion. This means that if one path is blocked, the network will automatically switch to a backup path to ensure that traffic continues to flow smoothly.

DWDM technology, on the other hand, allows multiple optical signals to be transmitted over a single optical fiber by using different wavelengths. This enables high-capacity data transmission over long distances.
