Recommended Solder and Wash Process
The AFCT-5943xxZ are compatible with industry-stan-
dard wave solder processes.
Process plug
This transceiver is supplied with a process plug for
protection of the optical port within the LC 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 with-
stand +85°C and a rinse pressure of 110 lbs per square
inch.
Recommended Solder fluxes
Solder uxes used with the AFCT-5943xxZ should be
water-soluble, organic fluxes. Recommended solder
uxes include Lonco 3355-11 from London Chemical
West, Inc. of Burbank, CA, and 100 Flux from Alpha-Met-
als of Jersey City, NJ.
Recommended Cleaning/Degreasing Chemicals
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptane
Other: naphtha.
Do not use partially halogenated hydrocar-
bons such as 1,1.1 trichloroethane, ketones such
as MEK, acetone, chloroform, ethyl acetate, meth-
ylene dichloride, phenol, methylene chloride, or
N-methylpyrolldone. Also, Avago Technologies does not
recommend the use of cleaners that use halogenated
hydrocarbons because of their potential environmental
harm.
LC SFF Cleaning Recommendations
In the event of contamination of the optical ports, the
recommended cleaning process is the use of forced
nitrogen. If contamination is thought to have remained,
the optical ports can be cleaned using a NTT interna-
tional Cletop stick type (diam. 1.25mm) and HFE7100
cleaning uid.
Regulatory Compliance
The Regulatory Compliance for transceiver perform-
ance is shown in Table 1. The overall equipment design
will determine the certication level. The transceiver
performance is oered as a gure of merit to assist the
designer in considering their use in equipment designs.
Electrostatic Discharge (ESD)
The device has been tested to comply with MIL-STD-
883E (Method 3015). It is important to use normal ESD
handling precautions for ESD sensitive devices. These
pre cautions include using grounded wrist straps, work
benches, and oor mats in ESD controlled areas.
Electromagnetic Interference (EMI)
Most equipment designs utilizing these high-speed
transceivers from Avago Technologies will be required
to meet FCC regulations in the United States, CENELEC
EN55022 (CISPR 22) in Europe and VCCI in Japan. Refer
to EMI section (page 9) for more details.
Immunity
Transceivers will be subject to radio-frequency electro-
magnetic elds following the IEC 61000-4-3 test method.
Eye Safety
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 foreseeable single fault conditions per
EN60825-1. Avago Technologies has tested the trans-
ceiver 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 trans-
ceivers 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 3.6 V transmitter V

CAUTION:
There are no user serviceable parts nor any mainte-
nance required for the AFCT-5943xxZ. All adjustments
are made at the factory before shipment to our custom-
ers. Tampering with or modifying the performance of
the parts will result in voided product warranty. It may
also result in improper operation of the circuitry, and
possible overstress of the laser source. Device degrada-
tion or product failure may result.
Connection of the devices to a non-approved optical
source, operating above the recommended absolute
maximum conditions or operating the AFCT-5943xxZ
in a manner inconsistent with its design and function
may result in hazardous radiation exposure and may
be considered an act of modifying or manufacturing
a laser product. The person(s) performing such an act
is required by law to recertify and reidentify the laser
product under the provisions of U.S. 21 CFR (Subchap-
ter J).
Design Support Materials
Avago Technologies has created a number of reference
designs with major PHY IC vendors in order to demon-
state full functionality and interoperability. Such design
information and results can be made available to the
designer as a technical aid. Please contact your Avago
Technologies representative for further information if
required.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to
each parameter in isolation, all other parameters having values within the recommended operating conditions. It
should not be assumed that limiting values of more than one parameter can be applied to the product at the same
time. Exposure to the absolute maximum ratings for extended periods can adversely aect device reliability.
