HFBR-789BHZ

HFBR-779BZ/BEZ/BHZ and HFBR-789BZ/BEZ/BHZ Pluggable Parallel Fiber Optic Modules, Transmitter and Receiver 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.

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 applications. See Figure 1 for the transmitter and Figure 2 for the receiver block diagrams. The HFBR-779BZ transmitter and the HFBR789BZ receiver modules provide very closely spaced, highspeed 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, 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. 2 COMPARATOR SHUT DOWN AMPLIFIER 12 DIN+ INPUT STAGE LEVEL SHIFTER 12 DRIVER D/A CONVERTER DIN- 12 VCSEL ARRAY SERIAL CONTROL I/O* 4 CONTROLLER D/A CONVERTER TEMPERATURE DETECTION CIRCUIT Figure 1.

These modules, with their shielded design, perform to the levels detailed in the Regulatory Compliance Table. The performance detailed in the Regulatory Compliance Table is intended to assist the equipment designer in the management of the overall equipment EMI performance. However, system margins are dependent on the customer board and chassis design. Immunity Equipment using these modules will be subject to radio frequency electromagnetic fields in some environments. These modules have good immunity due to their shielded designs. See the Regulatory Compliance Table for further detail. Eye Safety These 850 nm VCSEL-based modules provide eye safety by design. The HFBR-779BZ has been registered with CDRH and certified by TUV as a Class 1M device under Amendment 2 of IEC 60825-1. See the Regulatory Compliance Table for further detail. If Class 1M exposure is possible, a safety-warning label should be placed on the product stating the following: LASER RADIATION DO NOT VIEW DIRECTLY WITH OPTICAL INSTRUMENTS CLASS 1M LASER PRODUCT Connector Cleaning The optical connector used is the MTP® (MPO). The optical ports have recessed optics that are visible through the nose of the ports. The provided port plug should be installed any time a fiber cable is not connected. The port plug ensures the optics remain clean and no cleaning should be necessary. In the event the optics become contaminated, forced nitrogen or clean dry air at less than 20 psi is the recommended cleaning agent. The optical port features, including guide pins, preclude use of any solid instrument. Liquids are not advised due to potential damage. Process Plug Each parallel optics module is supplied with an inserted process plug for protection of the optical ports within the MTP® (MTO) connector receptacle. Handling Precautions The HFBR-779BZ and HFBR-789BZ can be damaged by current surges and over-voltage conditions. Power supply transient precautions should be taken. Normal handling precautions for electrostatic sensitive devices should be taken (see ESD section). The HFBR-779BZ is a Class 1M laser product.

For this parameter, input power is an average input optical power of –10.7 dBm and conditioned with 2.5 dB ISI (min), 33 ps DCD DJ (min), 6 dB ER (ER Penalty = 2.23 dB). All channels not under test are operating receiving data with an average input power up to 6 dB above PIN MIN. 5. Return loss is defined as the ratio, in dB, of the received optical power to the optical power reflected back down the fiber. 6.
