Note:
1. GND
is
the
symbol
for
signal
and
supply
(power)
common
for
the
QSFP+
module.
All
are
common
with
the
QSFP+
module
and
all
module
voltages
are
references
to
this
potential
unless
otherwise
noted.
Connect these directly to the host board signal-‐common ground plane.

6. Recommended host board power supply filtering is shown in Figure 4. Vcc Rx Vcc1 and Vcc Tx may be
internally connected within the QSFP+ Module in any combination. The connector pins are each rated
for a maximum current of 500 mA.
