General/Control Electrical Characteristics
(Over recommended operating conditions: Tc= 0ºC to +80ºC, V cc =3.3V + 5%)
Regulatory Compliance
The overall equipment design will determine the
certification level. The module performance is offered
as a figure of merit to assist the designer in considering
their use in equipment designs.
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, workbenches and floor mats in ESD
controlled areas. The module performance has been
shown to provide adequate performance in typical
industry production environments.
The second case to consider is static discharges to the
exterior of the equipment chassis containing the
module parts. To the extent that the MT-based
connector receptacle is exposed to the outside of the
equipment chassis it may be subject to whatever
system-level ESD test criteria that the equipment is
intended to meet. The module performance exceeds
typical industry equipment requirements of today.
Electromagnetic Interference (EMI)
Most equipment designs using these high-speed
modules from Avago Technologies will be required to
meet the requirements of FCC in the United States,
CENELEC EN55022 (CISPR 22) in Europe and VCCI in
Japan. These modules, with their shielded design,
perform to the limits listed in Table 1 to assist the
designer in the management of the overall equipment
EMI performance.

Immunity
Equipment utilizing these modules will be subject to
radio frequency electromagnetic fields in some
environments. These modules have good immunity to
such fields due to their shielded design.
Eye Safety
These 850 nm VCSEL-based transceiver modules
provide eye safety by design.
The HFBR-7924 has been registered with CDRH and
certified by TUV as a Class 1M device under
Amendment 2 of IEC 60825-1. See the Regulatory
Compliannce 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
MTP
The optical port has recessed optics that are visible
through the nose of the port. The port plug provided
should be installed whenever a fiber cable is not
connected. This ensures the optics remain clean and
no cleaning should be necessary. In the event of the
optics being contaminated, forced nitrogen or dry clean
air at less than 20 psi is the recommended cleaning
agent. The features of the optical port and guide pins
preclude the use of any solid instrument. Liquids are
not advised due to potential damage.
Application of wave soldering, reflow soldering and/or
aqueous wash processes with the HFBR-7924 modules
device on board is not recommended as damage may
occur.
Normal handling precautions for electrostatic sensitive
devices should be taken (see ESD section).
