A submarine optical transport link is a telecommunications system that uses fiber optic cables laid underwater for the transmission of large volumes of data at high speeds between two or more distant locations.

Within submarine transport, there is a configuration known as festoon, which refers to a specific design of submarine cable deployment where the cables follow a pattern connecting multiple coastal points, usually in a regional or semicircular route.

One of the longest festoons in the world is located in South America and extends over 3,500 km. Linking 12 coastal cities in Chile, from Arica to Puerto Montt, the network employs MPBC's advanced optical amplification technology. This cutting-edge solution, utilizing Dense Wavelength Division Multiplexing (DWDM), enables the reliable transmission of high-capacity data and internet services with a total bandwidth capability of up to 4 Tb/s.
