The AFBR-732BWZ transmitter and AFBR-742BZ receiver are high performance ber optic modules for parallel optical data communication applications. These 12- channel devices, operating up to 2.5Gbd per channel, provide a cost eective solution for short-reach appli- cations requiring up to 30 Gb/s aggregate bandwidth. These modules are designed to operate on multimode ber 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 AFBR-732BWZ transmitter module incorporates a 12- channel VCSEL (Vertical Cavity Surface Emitting Laser) array together with a custom 12-channel laser driver in- tegrated circuit providing IEC-60825 and CDRH Class 1M laser eye safety.The AFBR-742BZ receiver module contains a 12-channel PIN photodiode array coupled with a custom preamplier / post amplier 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. > High package density per Gb/s > 3.3 volt power supply for low power consumption > 850 nm VCSEL array source > 12 independent channels per module > Separate transmitter and receiver modules > 2.5 Gbd data rate per channel > Standard MTP (MPO) ribbon ber connector inter- face > 50/125 micron multimode ber operation: Distance up to 50 m with 50um, 500 MHz.km ber at 2.5 Gbd > Control I/O is LVTTL compatible > Manufactured in an ISO 9002 certied facility > Proprietary Ultra short link interconnects > The AFBR-732BWZ and AFBR-742BZ products are available for production orders through the Avago Component Field Sales oce.AFBR-732BWZ No EMI Nose Shield, with Heatsink AFBR-742BZ No EMI Nose Shield, with Heatsink AFBR-732BEWZ With EMI Nose Shield, with Heatsink AFBR-742BEZ With EMI Nose Shield, with Heatsink AFBR-732BEHWZ With EMI Nose Shield, No Heatsink AFBR-742BEHZ With EMI Nose Shield, No Heatsink >

The receiver section, Figure 2, contains a 12-channel AlGaAs/ GaAs photodetector array, transimpedance preamplier, lter, gain stages to amplify and buer 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. Avagos parallel optics solution combines twelve 2.5 Gb/s channels into discrete transmitter and receiver modules providing a maximum aggregate data rate of 30 Gb/s. Moreover, these modules employ a...

Many equipment designs using these high-data-rate modules will be required to meet the requirements of the FCC in the United States, CENELEC in Europe and VCCI in Japan. 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. The optical connector used is the MTP (MPO). The optical ports have...
