Electromagnetic Interference (EMI)
One of a circuit board designer’s foremost concerns is
the control of electromagnetic emissions from electronic
equipment. Success in controlling generated Electro-
magnetic Interference (EMI) enables the designer to pass
a governmental agency’s EMI regulatory standard and
more importantly, it reduces the possibility of interfer-
ence to neighboring equipment. Avago Technologies
has designed the AFCT-5942xxxZ to provide good EMI
performance. The EMI performance of a chassis is depen-
dent on physical design and features which help improve
EMI suppression. Avago Technologies encourages using
standard RF suppression practices and avoiding poorly
EMI-sealed enclosures.
Avago Technologies’ OC-48 LC transceivers (AFCT-
5942xxxZ) have nose shields which provide a convenient
chassis connection to the nose of the transceiver. This
nose shield and the underlying metalization (except ‘G’
options) improve system EMI performance by effectively
closing off the LC aperture. The recommended trans-
ceiver position, PCB layout and panel opening for both
devices are the same, making them mechanically drop-in
compatible. Figure 8 shows the recommended position-
ing of the transceivers with respect to the PCB and face-
plate.
Recommended Solder and Wash Process
The AFCT-5942xxxZ are compatible with industry-stan-
dard wave solder processes.
Process plug
This transceiver is supplied with a process plug for pro-
tection of the optical port within the LC connector recep-
tacle. This process plug prevents contamination during
wave solder and aqueous rinse as well as during han-
dling, shipping and storage. It is made of a high-tempera-
ture, molded sealing material that can withstand +85°C
and a rinse pressure of 110 lbs per square inch.

Recommended Solder fluxes
Solder fluxes used with the AFCT-5942xxxZ should be
water-soluble, organic fluxes. Recommended solder flux-
es include Lonco 3355-11 from London Chemical West,
Inc. of Burbank, CA, and 100 Flux from Alpha-Metals of
Jersey City, NJ.
Recommended Cleaning/Degreasing Chemicals
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptane
Other: naphtha.
D o not use p a r t i a l l y h a l o g e n a t e d hyd ro c a r -
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 nitro-
gen. If contamination is thought to have remained, the
optical ports can be cleaned using a NTT international
Cletop stick type (diam. 1.25mm) and HFE7100 cleaning
fluid.
