Understanding OTN — Optical Transport Network

An optical transport network, or OTN, is a communication network that uses optical fibers to transport high-speed and high-capacity data. This type of network is commonly used by telecommunications and internet service providers to transmit large amounts of data over long distances.

Optical fibers are thin strands of glass or plastic that are capable of transmitting light. This makes them ideal for transmitting data at high speeds, as light can travel over long distances with minimal loss of signal strength. In an OTN, data is encoded onto the light signals and sent through the optical fibers, allowing for the transmission of large amounts of data over long distances.

One of the key advantages of an OTN is its high capacity. Optical fibers can transmit data at speeds of up to 100 gigabits per second, making them much faster than traditional copper wire networks. This high capacity allows OTN networks to support a wide range of applications, including high-definition video, virtual reality, and cloud computing.

Another advantage of OTN networks is their reliability. Because the signal is transmitted through light, it is not susceptible to…
