HFBR-5911LZ/ALZ
Small Form Factor Optical Transceiver
for Gigabit Ethernet (1.25 GBd) and iSCSI Data Sheet

Description
The HFBR-5911LZ/ALZ optical transceiver from Avago Technologies is designed for use in short-reach multimode fiber optic (1000BASE-SX) links between Gigabit Ethernet networking equipment. Interoperable with all equipment meeting the Gigabit Ethernet industry standard, it is compliant with the Small Form Factor Multi Source Agreement and requires a 3.3 V dc power supply.
The electrical interface follows the 2 x 5 format while the optical interface uses the LC-Duplex connector.
