Description

technical field

[0001] The present application relates to the technical field of submarine cable systems, in particular to an intelligent feedback system with configurable modulation depth. Background technique

[0002] The submarine cable system includes two parts: underwater equipment and water equipment. The underwater equipment is buried on the seabed, including repeaters (RPT, Repeater), branchers (BU, Branching Unit), reconfigurable optical fork multiplexers (ROADM, Reconfigurable Optical Add / Drop Multiplexer), connecting cables; water equipment, located on land, including power supply equipment, network management system (NMS, Network Management System), submarine line termination equipment (SLTE, SubmarineLine Terminating Equipment), submarine cable monitoring equipment (SLM, Submarine Line Management).

[0003] The early submarine cable system only had the Command function, that is, the terminal station equipment was used to issue operating instructions to underwat...
