The RLH Fiber Optic Link Power Over Fiber (PoF) system provides power transmission over three multimode optical fibers. It is designed to provide true isolated power to a Fiber Optic Link CO side card when line sealing current or local AC power is not available. The PoF system delivers constant power and does not require backup batteries at the remote location.
Utilizing state of the art photonic technology the PoF system eliminates the need to run conductive copper wire into a high Ground Potential Rise (GPR) zone, and is a reliable and convenient remote powering solution.
PoF information brochure
The PoF system comprises 2 units; a Transmitter Unit to produce the light energy, and a Receiver Unit to convert that energy into DC power that can run a full spectrum of RLH Fiber Optic Links.
PoF Transmitter Unit
The PoF Transmitter unit is a self contained housing that may be 19/23” rack or wall mounted and measures H3.5”xW13”xD11”. It operates off of a 24- 56 VDC power source, and LED and LCD indicators located on the front panel report system status and operation.
The transmitter unit provides the light energy required for the receiver unit over 2 fiber strands. A third feedback fiber is used for system diganostics, and to control and monitor the Receiver Unit.
PoF Receiver Card
The PoF Receiver unit is a standard RLH single card form factor (7”x4”x1”) unit, and may be installed into any RLH Fiber Optic Link card housing. The receiver has two fiber ST photovoltaic power receivers (PPC) that convert the laser light into electrical energy, and a single fiber ST transmitter for monitoring and safety shutoffs in the event of a break in fiber continuity.
The PoF receiver provides 24VDC up to 25mA (0.6 Watts). For higher power or voltage applications, multiple receivers can be connected in series or parallel.
