HFBR-779BEZ

Notes:
1. Absolute Maximum Ratings are those values beyond which damage to the device may occur. See Reliability Data Sheet for specific reliability performance.
2. Between Absolute Maximum Ratings and the Recommended Operating Conditions functional performance is not intended, device reliability is not implied, and damage to the device may occur over an extended period of time.
3. This is the maximum voltage that can be applied across the Transmitter Differential Data Inputs without damaging the input circuit.
4. Case Temperature is measured as indicated in Figure 3.

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 HFBR-779BZ  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 12- 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 HFBR-779BZ  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.
