HFBR-2506AM

Agilent HFBR-1506AM/HFBR-2506AM Fiber Optic SMA Transmitters and Receivers for 16 MBd SERCOS Applications Data Sheet Description SERCOS, an acronym for SErial Realtime COmmunications Systems, is a standard digital interface for communication in industrial CNC applications. SERCOS is a European (EN 61491) and international standard (IEC 61491). The optical interface allows data rates of 2,4,8 and 16 MBd and data transfer between numerical controls and drives via fiberoptic rings, with voltage isolation and noise immunity. The HFBR-1506AM and HFBR2506AM products have a guaranteed performance up to 16 MBd. Package Information The transmitters and receivers are housed in a low-cost, dualin-line package that is made of high strength, heat resistant, chemically resistant and UL 94VO (UL file # E121562) flame retardant plastic. Both the transmitter and receiver are coated with a layer of conductive alloy for better air discharge (ESD) performance. The package is designed for auto insertion and wave soldering so it is ideal for high volume production applications. Handling and Design Information When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is sufficient to remove particles of dirt; methanol on a cotton swab also works well. Recommended Chemicals for Cleaning/Degreasing Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as 1,1,1 trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride or Nmethylpyrolldone. Also, Agilent does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. Features • Meets Industrial SERCOS 16MBd standard • SMA ports • 650 nm wavelength • Metal coated, plastic packaging • Specified for use with 1 mm POF and 200 µm HCS • DC - 16 MBd data rate Applications • Industrial Control Data Links • Factory Automation Data Links • Voltage Isolation Applications CAUTION: The small junction size inherent in the design of these components increases the components’ susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD. Table 1.

The high light output power enables the use of both plastic optical fiber (POF) and Hard Clad Silica (HCS). This transmitter can operate up to 16MBd using a simple driver circuit. The HFBR-1506AM is compatible with SMA connectors.
