1. Describe

The Versatile Link Series is a complete line of fiber optic link components for applications requiring a low cost solution. The HFBR-2521Z series includes transmitters, receivers, connectors and cables designed to simplify designs. This family of components is ideal for addressing voltage isolation/isolation, EMI/RFI immunity, or data security concerns. Logic-compatible receivers and complete specifications of each component simplify optical link design. Key optical and electrical parameters of links configured using the HFBR-2521Z series are fully guaranteed 0° to 70°C. A wide variety of package configurations and connectors provide designers with numerous mechanical solutions to meet application requirements. The transmitter and receiver assemblies are designed for high-volume/low-cost assembly processes such as automated insertion and wave soldering. The emitter contains a 660 nm LED. The receiver consists of a monolithic DC-coupled digital IC receiver with an open-collector Schottky output transistor. An internal pull-up resistor is available for the HFBR-2521Z receiver. Shielding has been integrated into the receiver IC to provide additional localized noise immunity. The internal optics are optimized for use with 1 mm diameter plastic optical fibers. The common link specification includes all connector interface losses. Thus, optical calculations for common link applications are simplified.
