Function&Application Scenarios

The ROPA 1620 is used to extend transmission distances in unrepeatered submarine cable systems. It couples the pump light and signal light sent from the remote end into the gain medium erbium-doped fiber to stimulate signal light amplification, passively regenerating optical signals. The pump light generated by the pumping source in the SLTE transmits over the submarine fiber to the ROPA 1620, integrated on the submarine cable to supply pump energy for the gain medium of the ROPA.
