■Multi-core POF can minimize light transmission loss when the fiber is bent by increasing the number of cores. - Transmission Loss (Guiding Loss) The light transmission characteristics of plastic optical fibers vary depending on the wavelength of light. - Weather Resistance Asahi Kasei's plastic optical fiber (POF) is primarily made of P-MMA resin, which has excellent weather resistance, so its initial performance rarely deteriorates over long periods. However, prolonged exposure to ultraviolet light may cause changes such as yellowing, so please be cautious. - Flexibility Compared to electrical wires, it has excellent fracture strength against bending, but extreme bends can cause light transmission loss. Please use it within the allowable bending radius for each grade. For wiring with extreme bends, we recommend using Asahi Kasei's "Multi-core POF," which does not experience a decrease in light quantity when bent. - Chemical Resistance Generally, exposure to organic solvents may cause a decrease in light transmission rate or mechanical strength, so please be cautious. For adhesive use, we recommend a room temperature curing two-component mixed type epoxy adhesive.

Asahi Kasei has developed a POF (Plastic Optical Fiber) that combines spinning technology cultivated through polymer technology and synthetic fibers. Utilizing highly transparent methacrylic resin as the core material and fluorine-based resin as the cladding material, POF is manufactured using the latest technology and is expected to be a promising material for signal transmission and image transmission applications. Plastic optical fiber consists of a core (the central part) made of a high refractive index component, which is covered by a cladding (the outer layer) made of a low refractive index component in a concentric arrangement. Light entering from one end of the optical fiber is transmitted to the other end by repeatedly undergoing total internal reflection at the boundary between the core and the cladding. ● Flexibility Compared to electric wires and other materials, it has excellent breaking strength under bending; however, extreme bends can cause light transmission loss. Please use it within the allowable bending radius for each grade. For wiring with extreme bends, we recommend using Asahi Kasei's "Multi-Core POF," which maintains light intensity even when bent. ● Chemical Resistance Plastic optical fibers can generally be affected by organic solvents, leading to a decrease in light transmittance or mechanical strength, so please be cautious. For adhesive use, we recommend a room-temperature curing two-component mixed epoxy adhesive.

- Heat resistance: The heat resistance of POF depends on the heat resistance of the plastic it is made from. - Flexibility: Plastic optical fibers have superior break strength under bending compared to electrical wires, but please use them within the allowable bending radius for each grade. For wiring with extreme bends, we recommend using Asahi Kasei's "Multi-Core POF," which does not experience a decrease in light transmission even when bent. - Chemical resistance: Plastic optical fibers can generally be affected by organic solvents, leading to a decrease in light transmission or mechanical strength, so please be cautious. <Handling Precautions> - Do not use for applications that come into contact with food, or for applications that directly contact the human body, such as catheters or endoscopes. If used for medical purposes, please consult with an Opto-Ron Science representative in advance. We will make an appropriate judgment in consultation with the manufacturer. - Plastic optical fibers (POF) are made of resin and are not designed to withstand excessive loads. - POF is made of resin, and if the environmental conditions for using POF are incorrect, there is a risk that the POF may break or its light guiding performance may decrease, resulting in a loss of light transmission functionality.

In many cases where high-frequency products are used, issues such as unwanted vibrations, imperfections in ground shielding, nonlinearity, gain peaking, and bandwidth reduction due to insufficient amplifier design can arise. However, Femto's current amplifiers are designed to adequately address these problems. They prevent gain peaking, vibrations, and significant bandwidth reduction, unaffected by the signal's source parameters or wiring, with a capacitance of up to 2nF. When the capacitance is a few pF, the bandwidth of high-frequency current amplifiers significantly decreases; however, Femto's high-speed current amplifiers are not subject to this limitation and are unaffected by capacitance with a wide range. They come with two trim pots for precise offset and bias control, allowing for flexible use. Input offset current correction can be adjusted over a wide range, fully maintaining dynamics even from signals with large DC components. The bias output voltage can be adjusted within -12 to +12V using this bias trim pot.
