The optical transmission
guideline is a supplement of the
German National DIN E 19258
standard draft. On the European
level, prEN 50254 is the draft of
the INTERBUS-S fieldbus.
Package Information
All HFBR-X5X5X series
transmitters and receivers are
housed in a low-cost, dual-in-line
package that is made of high
strength, heat resistant,
chemically resistant and UL 94
V-O (UL file # E121562) flame
retardant plastic. The
transmitters are easily identified
by the light grey colored
connector port. The receivers are
easily identified by the dark grey
colored connector port. The
package is designed for auto-
insertion and wave soldering so it
is ideal for high volume production
applications.
Handling and Design Information
When soldering, it is advisable to
leave the protective cap on the unit
to keep the optics clean. Good
system performance requires clean
port optics and cable ferrules to
avoid obstructing the optical path.
Clean compressed air often is
sufficient to remove particles of
dirt; methanol on a cotton swab
also works well.
Recommended Chemicals for
Cleaning/Degreasing X5X5X Products
Alcohols: methyl, isopropyl,
isobutyl.
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, Avago
does not recommend the use of
cleaners that use halogenated
hydrocarbons because of their
potential environmental harm.
Specified Link Performance
0˚C to +70˚C unless otherwise noted.

CAUTION: The small junction size inherent in the design of these components increases the
components’ susceptibility to damage from electrostatic discharge (ESD). It is advised that normal
static precautions be taken in handling and assembly of these components to prevent damage and/or
degradation which may be induced by ESD.
