ROPA REMOTE OPTICAL PUMP AMPLIFIER

 Extended spans between two nodes with remote signal amplification

• used in long single-span lines to increase the distance between two communication nodes
• configurations with counter and forward pumping are possible

The Remote Optical Pumping Amplifier (ROPA) consists of two functional units such as a passive part (sealed sleeve with erbium fiber) and an active part (pumping unit near the 1480 nm wavelength). The passive part is located far from the service nodes in the optical cable system itself.

The pumping of such amplifiers is carried out remotely via a telecommunications or additional fiber. Configurations of ROPA amplifiers are possible with counter (pump radiation is delivered from the receiving part) and forward pumping (pump delivery from the transmitting part).

ROPA increases the distance between two communication nodes.

HTF can help you design DWDM solution, >150km or more distance.
