Electromagnetic Interference (EMI)
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.
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.
DO NOT VIEW RADIATION DIRECTLY WITH
OPTICAL INSTRUMENTS.
