General/Control Electrical Characteristics
(Over recommended operating conditions: Tc= 0ºC to +80ºC, Vcc=3.3V + 5%)
Regulatory Compliance
The overall equipment design will determine the certi-
fication 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 de-
vices. 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 pro-
duction environments.
The second case to consider is static discharges to the
exterior of the equipment chassis containing the mod-
ule 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 equip-
ment requirements of today.
Electromagnetic Interference (EMI)
Most equipment designs using these high-speed mod-
ules 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 environ-
ments. 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-7924WZ has been registered with CDRH and
certified by TUV as a Class 1M device under Amend-
ment 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.

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 con-
nected. 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-7924WZ mod-
ules device on board is not recommended as damage
may occur.
Normal handling precautions for electrostatic sensitive
devices should be taken (see ESD section).
