The 820 nm Miniature Link Series of components is designed
to provide cost-effective, high-performance fiber optic
communication links for information systems and industrial
applications with link distances of several kilometers. With the
HFBR-24x6Z, the 125 MHz analog receiver, data rates of up to
160 MBaud can be attained.
Transmitters and receivers are directly compatible with
popular “industry-standard” connectors: ST, SMA, SC, and FC.
They are completely specified with multiple fiber sizes;
including 50/125 μm, 62.5/125 μm, 100/140 μm, and 200 μm.
Products are available in various options. For example,
transmitters with the improved protection option P show an
increased ESD resistance to the pins. This HFBR-141xPxZ
integrated solution is realized by including a Zener diode
parallel to the LED.
The HFBR-14x4Z high-power transmitter and HFBR-24x6Z
125 MHz receiver pair up to provide a duplex solution
optimized for 100BASE-SX. 100BASE-SX is a Fast Ethernet
Standard (100 Mb/s) at 850 nm on multimode fiber.
Evaluation kits are available for ST products, including
transmitter, receiver, eval board, and technical literature.

Note: For better readability of the electrical and optical specifications, all available options (P, T, C, and M) are covered by the HFBR-x4xxZ product name; exceptions
are explicitly noted.
Note: AFBR-24x8xZ receivers are designed for data rates from DC up to 50 MBaud. AFBR-24x9xZ supports transmissions from 100 KBaud up to 50 MBaud. Refer to
the separate data sheets for details about these digital optical receivers providing CMOS/TTL output logic.
Link Selection Guide
For additional information about specific links, see the individual link descriptions. The HFBR-1415Z can be used for increased
power budget or for lower driving current for the same Data Rates and Link Distances.
