and the external water pressure,
preventing damage to the box
due to pressure differentials.
• MacArtney has also launched
its new SubConn Micro Circular
9-contact connector. With
enhanced features designed to
minimise signal interference,
this connector ensures optimal
data accuracy and efficient
underwater operations.
“The standard 8-contact
connector is very good for high
bandwidth data, even up to
gigabit Ethernet,“
said Jørgensen.
“Over recent years, however, we
have recognised that the
instruments currently being
developed, provide increasingly
more data and for some, even
one gigabit is not enough
anymore.
“8-contact connectors are
typically used for signal
transmission, and some users
have requested an additional
contact for enhanced security.
The ninth contact in the new
connector is intended for a
screen, providing an extra layer
of data protection and ensuring
higher bandwidth.
“We have been running tests
and found that it is possible to
get 10 gigabit of data and now,
we are establishing what kind of
cable length this will work with,
targeting harness cables for
high bandwidth sensors such as
4K cameras.”
MONITORING TRIPOD
MacArtney has designed a tripod
assembly accommodating the
growing focus on innovative and
efficient solutions for subsea
infrastructure surveillance,
spanning defence,
communication, energy
production, scientific research,
and environmental monitoring.
“We intend to use these tripods
as a base on which to attach a
variety of sensors,” said Lars
Jørgensen, Head of Product
Management. “This would
typically include a number of
hydrophones in order to listen
out for underwater vehicles,
divers that shouldn’t be there or
possibly anchors dragging along
the seabed.
“It is suitable for
attaching
hydrophones from
any manufacturer.

We are currently working with a
new model from a Dutch
company: Optics11. These are
purely fibre optic, and as such,
there are no electronics. A
benefit of this is that signals can
travel great distances.
“Aside from the exhibited tripod,
we also construct other
geometrical frames to meet
specific sensor requirements. We
envisage the tripod and frames as
a suitable mount for subsea
cameras, sonars, oceanography
and seismic sensors or ADCP
systems.
“An important part of the
arrangement is employing our
connectivity and data acquisition
expertise. On this particular
tripod, we have also incorporated
a junction box as well as one of
our latest multiplexers.
The MacArtney oil-filled junction
box is a robust, reliable junction
box designed for underwater
applications. It is specially
engineered to withstand
harsh marine
environments and
ensure reliable
electrical connections.
