Handling
Process Plug
The HFBR-591xE and HFCT-591xE
SFF transceivers are supplied with a
process plug for protection of optical
ports. This process plug prevents
contamination during solder and
aqueous rinse as well as during
handling, shipping or storage. It is
made of high temperature, moulded
material containing an insert that
forms a seal around the optical port.
The multimode (black) and single
mode process plugs (blue) are not
inter changeable. The process plug is
capable of withstanding +80° C and
a rinse pressure of 110 psi.
Optical Path Cleanliness
To ensure optimum product per-
formance, the optical light path
must not be obscured by any con-
tamination. The following cleaning
procedure is suggested:
1) Use a nitrogen air gun, or similar,
2) Use a nitrogen air gun, or similar,
to blow clean the MT ferrule inside
the housing each time before
inserting the MT-RJ patchcord.
to blow clean the MT ferrule in
the MT-RJ patchcord each time
before mating with the module
or another patchcord.
3) Wipe the ferrule gently with IPA
4) Use a nitrogen air gun, or similar,
5) Put modules and patchcords
6) Use the modules process plug
Recommended Solder Fluxes and
Cleaning/Degreasing Chemicals
Solder fluxes used with the SFF
fiber optic transceiver should be
water-soluble, organic solder fluxes.
Some recommended solder fluxes
are Lonco 3355-11 from London
Chemical West, Inc. of Burbank, CA
and 100 Flux from Alpha metals of
Jersey City, NJ.
Recommended cleaning and de-
greasing chemicals for the SFF are
alcohol’s (methyl, isopropyl, isobutyl)
and aliphates (hexane, heptane).
Do not use partially halogenated
hydrocarbons for cleaning/degreas-
ing. Examples of chemicals to avoid
are 1.1.1 trichloroethane, ketones
(such as MEK), acetate, chloroform,
ethyl acetate, methylene dichloride,
phenaol, methylene chloride or N-
methylpyrolldone.
Thermal Analysis/Considerations
The HFCT-591xE single mode SFF
transceiver consumes a typical 600
mW of power. The case temperature
is approximately +5° C higher than
ambient temperature and the metal
shield of the transceiver enables
efficient power dissipation.

time after wiping the ferrule with
