Package and Handling Instructions
transceiver housing is made of
high strength, heat resistant,
chemically resistant, and UL
94V-0 flame retardant plastic.
Recommended Solder and Wash
The HFBR-53A3VEM/FM is
compatible with industry-
standard wave or hand solder
This transceiver is supplied with
a process plug (HFBR-5000) for
protection of the optical ports
within the duplex SC connector
receptacle. This process plug
prevents contamination during
wave solder and aqueous rinse as
well as during handling, shipping,
and storage. It is made of a high-
temperature, molded sealing
material that can withstand 80 °C
and a rinse pressure of 110 lbs
per square inch.
Recommended Solder Fluxes
Solder fluxes used with the
HFBR-53A3VEM/FM should be
water-soluble, organic fluxes.
Recommended solder fluxes
include Lonco 3355-11 from
London Chemical West, Inc. of
Burbank, CA, and 100 Flux from
Alpha-Metals of Jersey City, NJ.
Alcohols: methyl, isopropyl,
Aliphatics: hexane, heptane.
Other: soap solution, naphtha.
Do not use partially halogenated
hydrocarbons such as 1,1.1
trichloroethane, ketones such as
MEK, acetone, chloroform, ethyl
acetate, methylene dichloride,
phenol, methylene chloride, or
N-methylpyrolldone. Also, Agilent
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.

Table for transceiver
The overall equipment design will
determine the certification level.
The transceiver 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
The first case is during handling
of the transceiver prior to
mounting it on the circuit board.
It is important to use normal ESD
handling precautions for ESD
sensitive devices. These pre-
cautions include using grounded
wrist straps, work benches, and
floor mats in ESD controlled
areas. The transceiver perform-
ance has been shown to provide
adequate performance in typical
The second case to consider is
static discharges to the exterior
of the equipment chassis
containing the transceiver parts.
To the extent that the duplex SC
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 transceiver
performance is more robust than
typical industry equipment
requirements of today.
Electromagnetic Interference (EMI)
Most equipment designs utilizing
these high-speed transceivers
from Agilent will be required to
meet the requirements of FCC in
the United States, CENELEC
EN55022 (CISPR 22) in Europe
and VCCI in Japan. Refer to EMI
section (page 4) for more details.
Equipment utilizing these
transceivers will be subject to
fields in some environments.
These transceivers have good
immunity to such fields due to
their shielded design.
These laser-based transceivers
are classified as AEL Class I (U.S.
21 CFR(J) and AEL Class 1 per
EN 60825-1 (+A11). They are
eye safe when used within the
data sheet limits per CDRH. They
are also eye safe under normal
operating conditions and under
all reasonably forseeable single
fault conditions per EN60825-1.
Agilent has tested the transceiver
design for compliance with the
requirements listed below under
normal operating conditions and
under single fault conditions
where applicable. TUV Rheinland
has granted certification to these
transceivers for laser eye safety
and use in EN 60950 and EN
60825-2 applications. Their
performance enables the
transceivers to be used without
concern for eye safety up to
maximum volts transmitter VCC.
