Broadcom HFBR-14xxZ & HFBR-24xxZ 820nm Mini Link Series
Broadcom HFBR-14xxZ and HFBR-24xxZ 820nm Miniature Link Series of components are created to furnish cost-effective, high-performance, fiber-optic communication links for information systems and industrial applications with link distances of several kilometers. The HFBR-24x6Z, combined with a 125MHz analog receiver, results in data rates of up to 160Mbaud.
Transmitters and receivers are directly compatible with popular “industry-standard” connectors: ST, SMA, SC, and FC. The devices are fully specified with multiple fiber sizes, including 50/125μm, 62.5/125μm, 100/140μm, and 200μm.
The HFBR-14xxZ and HFBR-24xxZ 820nm Miniature Link Series are available in various options. For example, transmitters with the improved protection option P show an increased ESD resistance to the pins. The HFBR-141xPxZ integrated solution incorporates a Zener diode parallel to the LED.
The Broadcom HFBR-14x4Z high-power transmitter and the HFBR-24x6Z 125MHz receiver pair up to supply a duplex solution optimized for 100BASE-SX. The 100BASE-SX is a Fast Ethernet Standard (100Mb/s) at 850nm on multimode fiber.
