Fiber

SFP
Devices
An
optional
Gigabit
SFP
transceiver
can
be
used
for
a
backbone
connection
between
switches,
or
for
connecting
to
a
high
‐
speed
server.
Each
single
‐
mode
fiber
port
requires
9/125
micron
single
‐
mode
fiber
optic
cable
with
an
LC
connector
at
both
ends.
Each
multimode
fiber
optic
port
requires
50/125
or
62.5/125
micron
multimode
fiber
optic
cabling
with
an
LC
connector
at
both
ends.
WARNING
:
This
switch
uses
lasers
to
transmit
signals
over
fiber
optic
cable.
The
lasers
are
inherently
eye
safe
in
normal
operation.
However,
user
should
never
look
directly
at
a
transmit
port
when
it
is
powered
on.
WARNING
:
When
selecting
a
fiber
SFP
device,
considering
safety,
please
make
sure
that
it
can
function
at
a
temperature
that
is
not
less
than
the
recommended
maximum
operational
temperature
of
the
product.
You
must
also
use
an
approved
Laser
SFP
transceiver.
Step
1
.
Remove
and
keep
the
LC
port’s
rubber
plug.
When
not
connected
to
a
fiber
cable,
the
rubber
plug
should
be
replaced
to
protect
the
optics.
Step
2
.
Check
that
the
fiber
terminators
are
clean.
You
can
clean
the
cable
plugs
by
wiping
them
gently
with
a
clean
tissue
or
cotton
ball
moistened
with
a
little
ethanol.
Dirty
fiber
terminators
on
fiber
optic
cables
will
impair
the
quality
of
the
light
transmitted
through
the
cable
and
lead
to
degraded
performance
on
the
port.
