AFBR-POC406L

Data Sheet AFBR-POCxxxL Optical Power Converter Description AFBR-POCxxxL belongs to the Broadcom® Power Components product family and converts optical power to electrical power for applications requiring complete electrical isolation in highly demanding industrial environments and applications. AFBR-POCxxxL is an excellent choice for powering electronic circuitry where electrically-wired solutions are not feasible due to high voltage, electromagnetic inductance, or strong magnetic fields. AFBR-POCxxxL is a multi-junction compound semiconductor device that provides operating voltages for typical 3 VDC or 5 VDC applications, depending on the chip structure selected. Typically 600 mW of electrical power can be supplied by converting 1.5W (CW) of optical input power over an operating temperature range from –40°C to +85°C. Smart thermal design simplifies system integration. AFBR-POCxxxL is optimized for the efficient coupling of MM fibers with commonly available NA. All products are available with industry-standard ST or FC connectors. The AFBR-POCx04L optical power converters provide a typical output voltage level of 3.7V supporting most 3 VDC applications. The AFBR-POCx06L converters support most 5 VDC applications by providing a typical electrical output voltage level of 6.1V.

CAUTION! The small junction size inherent in the design of these components increases the components' susceptibility to damage from electrostatic discharge (ESD). Implement advanced static precautions in handling and assembling these components to prevent damage, degradation, or both that may be induced by ESD. Variants can be ordered with a threaded ST or FC port protected by port caps. When soldering, it is advisable to leave the protective port cap on the unit to prevent dirt buildup in the fiber or optical assemblies. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. The optic components are hermetically sealed in a TO header with a glass window. Any dirt particles in the optical path could reduce the conversion efficiency. AFBR-POCxxxL are photovoltaic devices. Unless for controlled testing purposes, do not apply an external voltage. For testing, make sure that polarities are maintained and do not exceed the value of open circuit voltage in the forward direction. This photovoltaic device should never be exposed to reverse voltage bias.

The device is a multi-junction compound semiconductor, which works as a power source without any applied external bias while providing electrical power to a load when illuminated. Unlike a standard photovoltaic device, such as a solar cell that is a large semiconductor pn-junction, the power converter is small. Typically, the device is illuminated by light emanating from an optical fiber; therefore, the light is highly concentrated. The AFBR-POCxxxL device is uniquely designed to handle concentrated light levels, which helps to maintain high output of both voltage and current.    Except for controlled testing, do not apply an external voltage. Never apply a reverse bias to the device. The "+" marking on the housing stands for anode; the "–" for cathode. The markings also indicate the current flow from "+" to" –", when a load is connected to the pins and light is coupled into the device. AFBR-POCxxxL devices operate without applying additional external voltage.  Use of voltage regulators is recommended for a stable, efficient, and controlled power extraction from AFBR-POCxxxL devices. Typically, photovoltaic devices, such as solar cells, do not have a continuous operating point and for optimum performance, the load must be adjusted accordingly. This adjustment is primarily due to the influence of the optical input power to the device output. Therefore, a fixed load power extraction is not an optimum method for power harvesting with solar cells. Conversely, the Broadcom optical power converters operate with controllable laser light coupled into optical fiber, which results in stabilized output of the AFBR-POCxxxL device. For most applications, combining the device with a voltage regulator, such as a DC/DC converter, is sufficient. Integration of ICs providing automatic maximum power point tracking (MPPT) is another option. Figure 2: Illustration of a Typical I-V Curve of Optical Power Converters IOUT Output Current (A) Ishort I at Pout max V at Pout max 0 Output voltage (V) Vopen VOUT Figure 2 illustrates the typical output current vs. output voltage characteristics of an optical power converter. At short circuit, the current output is at its maximum, but no power is delivered. At open circuit, the voltage is at its maximum; however, no power can be extracted. In between, a maximum power point exists, which is the product of the current and the voltage at that specific point. In an ideal application, the load would be tailored to that maximum power point.

The minimum and maximum fiber core diameter that can be used with AFBR-POCxxxL products is related to the fiber-specific numerical aperture value.Typically fibers with core diameter from 50 µm to 200 µm match with the specified NA range (0.22 to 0.375). For highest energy conversion efficiency fibers with NA from 0.22 to 0.28 are recommended. b. Fiber length depends on application requirements, mainly depending on fiber attenuation. Exemplarily a typical GI-MM 62.5 µm/125 µm fiber has an attenuation of around 3.5 dB/km at 830 nm.
