Introduction EMO Marine Technologies Ltd

Electrical

Mechanical

Optical

Specializing in sub-sea, fiber optic communications,

Typically for Remotely Operated Vehicles (ROVs),

And sub-sea observation/sensor platform systems.

What is Multiplexing? Multiplexing converts multiple system inputs into a single common transmission line, which can be transferred over a great distance as a common signal, and then de-multiplexed back into multiple system outputs. Multiplexing can take place at different levels:-

• Time Division Multiplexing (TDM) • Wavelength Division Multiplexing (WDM) • Coarse Wavelength Division Multiplexing (CWDM)

ROV Technology ROV = REMOTELY OPERATED VEHICLE

• Subsea robotic vehicle controlled by a “pilot” on a ship

• ROV launched from vessel and connected via a cable (umbilical + tether)

• Power is transmitted over copper in the cable; video and data communications are transmitted over optical fiber in the cable

• ROVs range in size from hand-held to the size of a van or bus (workclass ROVs)

• max. depth is typically 3000 – 6000 m for workclass ROVs

Why Fiber Optic?

FIBER ADVANTAGES

• Bandwidth: Many Gb/s, up to Tb/s in Telecom

• Distance: Capable of 100’s km without repeaters

• Small Size: Reduces diameter of ROV cables

• Lightweight: Reduces weight of ROV cables

• Immunity: Not affected by electrical interference

• Security: No radiated signal; difficult to tap undetected

• Isolation: Eliminates “ground loops”; no shock hazard

What can we do with fiber? Analog data (e.g. Video, and sonar)

Communication data - Serial Data (RS-232, RS-485/422) - Ethernet Data

ROV Devices: Cameras, Thrusters, Sonar, Manipulators, Hydrophones, Sub-sea tooling

The Mini-T MUX System The EMO Mini-T Multiplexer system offers the smallest form-factor sub-sea MUX housing in todays underwater market. At 4-inch in diameter, And 13-inch in Length, the Mini-T can be integrated into ROVs of ALL sizes and types, and is not limited to larger working class vehicles with larger payload capacity. The Mini-T can accept and convert the following channel types into a common fiber optic transmission: • Video (NTSC/PAL) • SDI/HD-SDI High Definition Video • Serial Data (RS-232/485/422) • Ethernet (10/100 Base-T) • GBE Gigabit Ethernet (1000Mbps)

The Mini-T MUX System The Mini-T MUX placed next to an industry standard sub-sea MUX bottle

DOMINO-7 MUX A bigger system,

for more channels…..

offers far more advanced capability in terms of sub-sea power management, fiber redundancy, and top-side diagnostics in the form of both LEDs at the rack, plus a detailed Ethernet + software + GUI package.
