the cable for UTP; and 100x the diameter of the
cable for ber.
• Avoid letting the cable t wist too much to
prevent excessive strain on internal cables.
• Place cable ties at regula r intervals, being
careful not to overtighten them. Avoid
using ties with ber cable.
• Don’t stretch cable, especi ally around
corners, in vertical cable trays and whe n spanning long distances.
Cable Selection
Use 100 Ohm Category 5, 5e or 6 unshielded twisted -pair (UTP) or shielded
twisted-pair (STP) cable for 1000Base-T congur ations, referring to the
pin assignments below as needed.
NOTE: All Category 5 UTP
cable used for 100Base-TX
connections should also work
for 1000Base-T providing all
four wire pairs are connected.
It is recommended, however,
that Cat6 cable be used for all
critical or new installations.
Positioning the Converter
The location of the converter during operati on can greatly affect its

Try to
maintain
a bend
radius of
(min.) 4x
the diameter
of the cable
for UTP and
100x for fiber.
Try not to
allow the
cable to
twist too
much - this
creates a
strain on
the internal
cables.
Place cable ties
at regular
intervals - do
not over tighten
cable ties - try
to avoid using
with fiber.
Do not stretch
the cable
especially on
corners, in
vertical cable
trays and when
spanning long
distances.
