HFBR-779BZ/BEZ/BHZ and HFBR-789BZ/BEZ/BHZ Pluggable Parallel Fiber Optic Modules, Transmitter and Receiver www.DataSheet4U.com Data Sheet Description The HFBR-779BZ transmitter and HFBR-789BZ 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-779BZ transmitter module incorporates a 1 2 - channel VCSEL (Vertical Cavity Surface Emitting Laser) array together with a custom 12-channel laser driver integrated circuit providing IEC-60825 and CDRH Class 1M laser eye safety. The HFBR-789BZ receiver module contains a 12-channel 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-779BZ No EMI Nose Shield HFBR-789BZ No EMI Nose Shield HFBR-779BEZ With Extended EMI Nose Shield HFBR-789BEZ With Extended EMI Nose Shield HFBR-779BHZ No EMI Nose Shield, No Heatsink HFBR-789BHZ No EMI Nose Shield, No Heatsink Design Summary: www.DataSheet4U.com Functional Description, Receiver Section The receiver section, Figure 2, contains a 12channel AlGaAs/ GaAs photodetector array, transimpedence 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 the 12 channels. If loss of signal is detected on an individual channel, that channel output is squelched. Packaging The flexible electronic subassembly was designed to allow high-volume assembly and test of the VCSEL, PIN photo diode and supporting electronics prior to final assembly. Regulatory Compliance The overall equipment design into which the parallel optics module is mounted will determine the certification level. The module performance is offered as a figure of merit to assist the designer in considering their use in the equipment design. Organization Recognition See the Regulatory Compliance Table for a listing of the standards, standards associations and testing laboratories applicable to this product. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. The first case is during handling of the module prior to mounting it on the circuit board. It is important to use normal ESD handling precautions for ESD sensitive devices. These precautions include using grounded wrist straps, work benches, and floor mats in ESD controlled areas. The second case to consider is static discharges to the exterior of the equipment chassis containing the module parts. To the extent that the MTP® (MTO) connector receptacle is exposed to the outside of the equipment chassis it may be subject to system level ESD test criteria that the equipment is intended to meet. See the Regulatory Compliance Table for further details. Design for low-cost, high-volume manufacturing Avago Technologies’ 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 highdensity cards, have excellent EMI performance, and interface with the industry standard MTP®/ MPO connector systems. They provide the most cost-effective high- density (Gbd per inch) solutions for high-data capacity applic.
