Overview

Our patented Power Over Fiber (PoF) system provides power transmission over three multimode (62.5/125) optical fibers. The PoF system is able to provide true isolated power to a remote location utilizing Laser Light at the transmitter and a photovoltaic power converter at the remote location. The remote location device utilizes super capacitors to ensure a smooth and constant voltage is supplied to the remotely powered devices. RLH patented PoF system utilizes state of the art photonic technology and safety interlock systems to provide a convenient method of remote powering RLH's low power consumption Fiber Link Cards or other low power consumption devices.

Transmitter

The PoF Transmitter unit is a self contained housing that may be 19/23” rack or wall mounted. The housing is constructed of powder coated aluminum with LED and LCD indicators located on the front panel to report system status and operation. The PoF transmitter requires a 24~56 VDC power source. The transmitter unit contains two high power laser diodes and one fiber receiver for signal feedback.

Receiver

The PoF receiver card may be installed into any Fiber Optic Link card housing. The PoF receiver card has two fiber ST photovoltaic power converters (PPC) and one fiber ST transmitter. The PPC converts laser light into electricity. The PoF Receiver will also transmit a fiber signal to the PoF transmitter unit for voltage monitoring and safety shutoffs in case of a break in fiber continuity. The PoF receiver will provide up to 1 Watt of 24 Volt DC Power, power output attenuates over distance. For higher power or voltage applications systems can be use together with the receiver cards connected in series or parallel.
