Data Sheet
Power-Over-Fiber Kit
From the world leader in power-over-fiber components, the Lumentum PPM-500-K is a
photonic power module kit capable of delivering up to 500 mW of electrically isolated power
over distances up to 500 meters.
The PPM-500-K combines a high-efficiency Lumentum fibercoupled laser diode and electronic drive circuitry in a single,
enclosed aluminum module. At the other end of the fiber, a
photovoltaic power converter (PPC) delivers electrically isolated
power at a convenient and minimum 3.2 V (4E) or 5.2 V (6E).
Key Features
• 100% isolated electrical power
The PPM-500-K kit includes one PPC. At 500 mW of power
output, the PPC will deliver a maximum operating current of
160 mA (4E) or 125 mA (6E). The optimum operation of the kit is
at 100 – 400 mW at which a suitable voltage regulator (not
included) can deliver consistent voltages of 3.3 V (4E)
and 5.0 V (6E).
• Built-in triggering option
The drive circuitry incorporates an efficient switching power
supply which reduces heat-dissipation requirements by more
than 60% compared to previous PPM products. Electrical power,
laser power control, and power monitoring are all accessed via a
single 6-pin connector.
For requirements above 500 mW, kits can be combined in
parallel. With its efficient design, more than one PPM-500-K can
share an external heat sink to save space.
• Minimum voltage: 3.2 V (4E), 5.2 V (6E)
• Up to 500 mW output; kits can be combined to deliver
1000 mW and above
• FC standard (ST as an option)
• Field-proven reliability
Applications
• Remotely located electronics, data logging circuitry,
and sensors
• Utility-based, high-voltage AC/DC current
measurements (>100 kV)
• Test labs requiring 100% EMI immunity
• Environments requiring spark-free delivery of electrical power
• Enhanced isolation for IGBTs serving noisy or sensitive electric
drive controls

notes, a white paper, and a manual with details and specifications

Laser Driver Characteristics
Laser driver circuitry provides the proper current to the laser in
direct relation to the set voltage. This ensures a continuous and
stable light output. The maximum light output at full current is
2 W. Modulation can be superimposed to enable transmitting
triggering functions.

Max Electrical Power (mW)
Isolated Electric Power Delivery Characteristics
The PPC receives laser light transmitted over fiber and converts
it into useful, 100% isolated electrical power. The maximum
power output, Pmax, occurs at the point where the product of
current and voltage is maximized. This is the ideal point of
operation and, with proper voltage regulation, the output from
the PPC can be optimized.
Detailed PPC Operation
The maximum electrical power output from the PPC is shown as a
function of input laser power levels. For the PPC-6E, the power
output can be seen to be almost linear until approximately 1 W of
incident laser light. For higher light levels, resistance effects
decrease the available voltage, leading to an overall decrease in
the conversion of light to electrical power. Therefore, the overall
power is no longer linear although the current from the PPC
continues in a linear fashion as can be seen in the table. The most
optimum operation of the PPC is with an incident laser light level
of 1 – 1.5 W.

Optical Power (W)
Since the PPC is designed to operate with multimode optical fiber,
it is necessary to use a fiber patch cord between the laser and
driver fiber pigtail and the PPC. A minimum length of 10 meters
and preferably 50 meters is recommended to (a) scramble all the
modes and (b) reduce any risk for back reflection. Under no
circumstance should the fiber pigtail be connected directly into
the PPC; this fiber has a different core diameter and numerical
aperture and is designed to couple equally well into 62.5, 105,
and 200 µm core fiber.
