This Presentation was originally given on February 2014, by Leighton Mauro, at the Underwater Intervention conference, and it details the following: The importance of high definition cameras and the manner by which they facilitate an ROV having greater visibility when performing subsea work. It also covers the critical role that subsea connectors hold in ensuring that high definition cameras perform at their most optimal level.

February 2014
• HD cameras, specialized cable, optical and hybrid
connectors have played a vital role in opening new doors to
the ROV industry
• High definition has proven valuable at greatly increasing
manipulator skills of the operator, saving both time and
improving task accuracy
• HD cameras can be utilized in many different applications
with an ROV, such as monitoring, positioning, inspection, and
environmental and biological data collection analysis to
name a few

• Important questions to know when implementing HD
– Is the system going to be running on 1080i or 720p?
– Will you be connecting with a coaxial RG75, mini-coax,
or standard subsea cable?
– What is the depth rating and how long will you need to
run your coax cable/signal?
– Component, HD-SDI or HD-SDI Over Fiber Output

BENEFITS OF HDTV vs SDTV
• High Definition has twice the vertical and horizontal
resolution than your conventional SDTV (Standard
Definition Video) signals.
• 4x better picture detail than your standard SDTV.
• Increased color fidelity. Another upside of using HD is
the lack of color interference, which can be a major
problem when dealing with composite NTSC and PAL video
images.

Additional Benefits of
High Definition
• The much increased resolution available from HDTV
means that high-quality video inspection and survey tasks
can be performed faster and better.
• Full 1080i HDTV video offers the equivalent of a
2MPixel stills image on every single video frame. This
allows video inspections to be more detailed, and
potentially reduces the need for stills photographic
inspection.
• For remote manipulator operations, HDTV potentially
allows complex manipulative tasks to be completed faster
and more easily, with less operator fatigue.

• Underwater connectors are used for joining up electrical
or optical circuits underwater
• They provide a termination of an underwater cable or
oil-filled hose, containing electrical conductors, optical
fibers or both
• One example being used in the industry, is the 55 Series
type connector. SEA CON®’s 55 is suitable for a variety
of applications including ROV’s, underwater cameras,
diver communications, lights and pan and tilts

CONNECTORS USED ON HD CAMERAS
A good example would be SEA CON®’s
75 ohm coax connector which was
developed in conjunction with a camera
manufacturer where a new HD camera
required impedance matched coax and
signal lines

WHAT IS CHALLENGING ABOUT HD
CONNECTORS?
• Type of signal
• Bandwidth
• Signal interference
• Number of channels

19. www.seaconworldwide.com

OPTICAL CONNECTOR
• Why hybrid?
• Optical for signal
• Electric for power
• One connector or two?
• Cost of hybrids are typically more but split
terminations can also incur cost
• Optics allow you to achieve much longer
transmission distances

FIBER VS COPPER
Type Advantages Disadvantages
Fiber
• Higher bandwidth speed
• Cost (Long Haul)
• Lighter weight for large
systems
• More complex terminations
• Initial cost and additional
equipment needed to install
and service
• Possible pressure
dependent loss
Copper
• Electrical power
Transmission
• Cost Advantage (Less costly
connectors and electronics)
• Electrical /Copper is a
known Technology
• Limited in Speed and
Bandwidth
• Limited Transmission
Distances
• Increased Weight and Size

ADVANTAGES OF OPTICAL CONNECTORS
• Using optical allows significantly greater
quantity of data to be transmitted at faster
rates
• Weight and size. They are significantly lighter
and smaller than a comparable copper
assembly
• Easily carry power where the power over
optics market is not yet at a marketable stage
