HFBR-2521Z Versatile Link The Versatile Fiber Optic Connection

Description

The Versatile Link series is a complete family of fiber optic link components for applications requiring a low cost solution. The HFBR-0500Z series includes transmitters, receivers, connectors and cable specified for easy design. This series of components is ideal for solving problems with voltage isolation/insulation, EMI/RFI immunity or data security. The optical link design is simplified by the logic compatible receivers and complete specifi-cations for each component. The key optical and electrical parameters of links configured with the HFBR-0500Z family are fully guaranteed from 0° to 70°C.

A wide variety of package configurations and connectors provide the designer with numerous mechanical solutions to meet application requirements. The transmitter and receiver components have been designed for use in high volume/low cost assembly processes such as auto insertion and wave soldering.

Transmitters incorporate a 660 nm LED. Receivers include a monolithic dc coupled, digital IC receiver with open collector Schottky output transistor. An internal pullup resistor is available for use in the HFBR-25X1Z/2Z/4Z receivers. A shield has been integrated into the receiver IC to provide additional, localized noise immunity.

Internal optics have been optimized for use with 1 mm diameter plastic optical fiber. Versatile Link specifications incorporate all connector interface losses. Therefore, optical calculations for common link applications are simplified.

Package and Handling Information

The compact Versatile Link package is made of a flame retardant VALOX® UL 94 V-0 material (UL file # E121562) and uses the same pad layout as a standard, eight pin dual-in-line package. Vertical and horizontal mountable parts are available. These low profile Versatile Link packages are stackable and are enclosed to provide a dust resistant seal. Snap action simplex, simplex latching, duplex, and duplex latching connectors are offered with simplex or duplex cables.

Notes:

1. Measured at the end of the fiber optic cable with large area detector.

2. Optical flux, P (dBm) = 10 Log P(µW)/1000 µW.

3. Because of the very high sensitivity of the HFBR-25X3Z, the digital output may switch in response to ambient light levels when a cable is not occupying the receiver optical port. The designer should take care to filter out signals from this source if they pose a hazard to the system.

4. Including current in 3.3 k pull-up resistor.
