Abstract: Methods and systems for optical communication in a submarine network are provided. An input signal is received from a terminal at a reconfigurable branching unit (BU), wherein the BU enables bidirectional transmission between any two terminals, and the input signal is demultiplexed into at least one individual waveband or wavelength using at least one demultiplexer. Each demultiplexed waveband is passed through optical switches, with corresponding optical switches for the same demultiplexed waveband provided for transmission in the reverse direction. Independent per-waveband switching is performed using a demultiplexer-switch-multiplexer (DSM) architecture. Each demultiplexed waveband is multiplexed at each output port using at least one multiplexer to combine signals from different sources, and combined signals are transmitted to a destination terminal.

Abstract: Systems and methods for data transport, including submarine reconfigurable optical add/drop multiplexers, branching units configured to receive signals from trunk terminals (TTs), and dummy light filters configured to pass useful signals through the filters, and to reflect dummy light. Optical interleavers are configured to separate useful signals into two or more groups of optical channels, and the optical channels are set to a frequency of either a left or a right portion of a total channel bandwidth. De-interleavers merge signal groups together from trunk terminals, and lasers at each of the transponders at the source terminals are configured to adjust a destination of a channel by fine tuning a frequency or wavelength of the one or more signals.
