Electromagnetic Interference (EMI)
Connector Cleaning
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 optical ports have recessed optics that are
visible through the nose of the ports. 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.

Handling Precautions
Eye Safety
The HFBR-772BZ and HFBR-782BZ can be
damaged by current surges and overvoltage
conditions. Power supply transient precautions
should be taken. Application of wave
soldering, reflow soldering and/or aqueous wash
processes with the parallel optic device on
These 850 nm VCSEL-based modules provide
eye safety by design. The HFBR-772BZ 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 board is not recommended as damage may
possible, a safety-warning label should be
placed on the product stating the following:

Normal handling precautions for electrostatic
sensitive devices should be taken (see ESD
