HFBR-5111

The HFBR-511X family of transceivers from Hewlett-Packard consists of high performance, cost effective modules for optical data communication applications at the 100 Mbps/125 MBd rate.

The  HFBR-511X  transceivers feature full compliance with the Fiber Distributed Data Interface (FDDI) Physical Media Dependent (PMD) standard. This standard has been approved as an International Standard, ISO/IEC 9314-3, and an American National Standard, ANSI X3.166 - 1990. The HFBR-5111 represents the 2x11 package style. The "2x11" denotes two rows of eleven pins. The HFBR-5112 and HFBR-5113 represent the Narrow and Standard 1x13 package styles, respectively. The "1x13" denotes one row of thirteen pins.

The  HFBR-511X  modules are designed for 50 or 62.5 mm core multimode optical fiber and operate at a nominal wavelength of 1300 nm. Each transceiver incorporates our high-performance, reliable, long-wavelength optical devices and proven circuit technology to give long life and consistent performance.

The  HFBR-511X  transceivers are optimized for 125 MBd operation but can be used over a wide range of signal rates. The transceivers are guaranteed to meet FDDI PMD specifications when used within the operating conditions specified in this document.

These HFBR-511X Series transceivers are also useful for both ATM 100 Mbps interfaces and Fast Ethernet 100 Base-FX interfaces. The ATM Forum User- Network Interface (UNI) Standard, Version 3.0, defines the Physical Layer for 100 Mbps Multimode Fiber Interface for ATM in Section 2.3 to be the FDDI PMD standard. Likewise, the Fast Ethernet Alliance defines the Physical Layer for the 100 Base-FX Version of IEEE 802.3u to be the FDDI PMD standard.

Hewlett-Packard also provides several other FDDI products compliant with the FDDI Low Cost Fiber (LCF) -PMD and Single Mode (SM) -PMD standards. These products are available with ST, SC, and FC connector styles.  HFBR-511X  are available in the 1x9 transceiver and 14- and 16-pin transmitter/ receiver package styles for those designs that require these alternate configurations.
