Power Supply for Optical Cable Repeater Station
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. Spellman High Voltage is the leading independent supplier of Power Feed Equipment to the Telecom industry. Wavelength Division Multiplexing (WDM), which was introduced in the 2000s, made it possible for a single optical fiber to send multiple signals at a time, leading to. Due to the requirement of long distance undersea communication system, the traditional optical fiber cable connection is not enough capability to transmit optical signal, but different from the terrestrial signal reinforce equipment, the marine system need the wet plant “Repeater” to amplify the.
