Power Feeding Equipment (PFE)

Submarine cable transmission link is usually a constant current system, Power feeding equipment provides power to the submarine cable system. 

In line with industry standards for wet plant products power supply equipment

PFE is located in the terminal station and can safely convert the -48V low voltage to the constant current required for the underwater device. Huawei Marine utilizes two types of PFE produced by Spellman High Voltage Electronics, as follows:
