HFBR-772BZ/BEZ/BHZ/BEHZ and HFBR-782BZ/BEZ/BHZ/BEHZ www.DataSheet4U.com Pluggable Parallel Fiber Optic Modules, Transmitter and Receiver Datasheet Description The HFBR-772BZ transmitter and HFBR-782BZ receiver are high performance fiber optic modules for parallel optical data communication applications. These 12-channel devices, operating up to 2.7 Gbd per channel, provide a cost effective solution for short-reach applications requiring up to 32 Gb/s aggregate bandwidth. These modules are designed to operate on multimode fiber systems at a nominal wavelength of 850 nm. They incorporate high performance, highly reliable, short wavelength optical devices coupled with proven circuit technology to provide long life and consistent service. The HFBR-772BZ transmitter module incorporates a 12- channel VCSEL (Vertical Cavity Surface Emitting Laser) array together with a custom 12channel laser driver integrated circuit providing IEC-60825 and CDRH Class 1M laser eye safety. The HFBR-782BZ receiver module contains a 12channel PIN photodiode array coupled with a custom preamplifier / post amplifier integrated circuit. Operating from a single +3.3 V power supply, both modules provide LVTTL or LVCMOS control interfaces and Current Mode Logic (CML) compatible data interfaces to simplify external circuitry. The transmitter and receiver devices are housed in MTP®/MPO receptacled packages. Electrical connections to the devices are achieved by means of a pluggable 10 x 10 connector array.

HFBR-772BZ HFBR-782BZ HFBR-772BEZ HFBR-782BEZ HFBR-772BHZ HFBR-782BHZ HFBR-772BEHZ HFBR-782BEHZ No EMI Nose Shield No EMI Nose Shield With Extended EMI Nose Shield With Extended EMI Nose Shield No Heatsink, No EMI Nose Shield No Heatsink, No Nose Shield With Extended EMI Nose Shield, No Heatsink With Extended EMI Nose Shield, No Heatsink Design Summary: www.DataSheet4U.com Design for low-cost, high-volume manufacturing Avago’s parallel optics solution combines twelve 2.7 Gbd channels into discrete transmitter and receiver modules providing a maximum aggregate data rate of 32 Gb/s. Moreover, these modules employ a heat sink for thermal management when used on high-density cards, have excellent EMI performance, and interface with the industry standard MTP®/MPO connector systems. They provide the most costeffective high- density (Gbd per inch) solutions for high-data capacity applications. See Figure 1 for the transmitter and Figure 2 for the receiver block diagrams. The HFBR-772BZ transmitter and the HFBR782BZ receiver modules provide very closely spaced, high-speed parallel data channels. Within these modules there will be some level of cross talk between channels. The cross talk within the modules will be exhibited as additional data jitter or sensitivity reduction compared to single-channel performance. Avago Technologies’ jitter and sensitivity specifications include cross talk penalties and thus represent real, achievable module performance. Functional Description, Transmitter Section The transmitter section, Figure 1, uses a 12channel 850 nm VCSEL array as the optical source and a diffractive optical lens array to launch the beam of light into the fiber. The package and connector system are designed to allow repeatable coupling into standard 12-fiber ribbon cable. In addition, this module has been designed to be compliant with IEC 60825 Class 1 eye safety requirements. The optical output is controlled by a custom IC, which provides proper laser drive parameters and monitors drive current to ensure eye safety. An EEPROM and state machine are programmed to provide both ac and dc current drive to the laser to ensure correct modulation, eye diagram and extinction ratio over variations of temperature and power supply voltages. Functional Description, Receiver Section The receiver section, Figure 2, contains a 12channel AlGaAs/ GaAs photodetector array, transimpedance preamplifier, filter, gain stages to amplify and buffer the signal, and a quantizer to shape the signal. The Signal Detect function is designed to sense the proper optical output signal on each of t.
