Single

‐
RX
Configuration
The
Solarflare
adapter
will
support
a
receive
(RX)
only
fiber
cable
configuration
when
the
adapter
is
required
only
to
receive
traffic,
but
have
no
transmit
link.
This
can
be
used,
for
example,
when
the
adapter
is
to
receive
traffic
from
a
fiber
tap
device.
Solarflare
have
successfully
tested
this
configuration
on
a
10G
link
on
SFN5000,
SFN6000,
SFN7000
and
SFN8000
series
adapters
when
the
link
partner
is
configured
to
be
TX
only
(this
will
always
be
the
case
with
a
fiber
tap).
Some
experimentation
might
be
required
when
splitting
the
light
signal
to
achieve
a
ratio
that
will
deliver
sufficient
signal
strength
to
all
endpoints.
Solarflare
adapters
do
not
support
a
receive
only
configuration
on
1G
links.
