Instrument Description
Branching Unit
Branching Units are developed by Alcatel-Lucent and used to connect the nodes of the NEPTUNE observatory to the main backbone cable loop. Branching units use passive optical couplers to split communication signals between the backbone and the spur cables on the NEPTUNE observatory. Power to the nodes is controlled in the branching units and nodes can be electrically disconnected from the main cable.
