Power Feeding Equipment (PFE) is a critical power supply system designed to energize optical amplifiers (repeaters) in long-distance submarine fiber-optic networks.
Submarine cables transmit data across vast distances, which leads to the attenuation of optical signals. To maintain signal integrity, optical repeaters are installed at regular intervals along the seabed. The PFE delivers power to these repeaters through the cable's central conductor.
Because long submarine cables exhibit high capacitance, utilizing Alternating Current (AC) would result in significant reactive power loss and voltage drops. Consequently, PFE systems employ High-Voltage Direct Current (HVDC) with precise constant-current control to ensure stable power delivery over thousands of kilometers.
Matsusada Precision's programmable high-voltage DC power supplies are engineered for high reliability and stability. With advanced constant-current capabilities and a compact design, they are an ideal choice for PFE system development, testing, and integration.
