Presenter Profile

Pete Barletto joined the Regional Scale Nodes program in May 2007 after many years in the submarine cable segment of the telecommunications industry. While working for Tyco Telecommunications, Barletto was responsible for the planning, implementation and operation of a global network. Most and operation of a global network. Most recently, he was Vice President of Network Services and Operations for VSNL and was responsible for Operations and Maintenance planning, worldwide real estate management, collocation service implementation, and strategic studies.

Ocean Observatories Initiative

• The Ocean Observatories Initiative (OOI) is a

National Science Foundation (NSF) Program:

–Coastal & Global Scale Nodes (CGSN) –Regional Scale Nodes (RSN)

Regional Scale Nodes Primary Infrastructure

• 25 year design life, two cables
• Single Fiber pair equipped with 24 10Gb/s

wavelengths

• Constant voltage – 10,000V

6

• Each Primary Node supplies up to 8KW of

power and redundant 10Gb/s of bandwidth to

• Seven Science ports – 5 @ 375V and GigE and

2 @ 375V and 10Gb/s

Regional Scale Nodes Secondary Infrastructure

• Extension cables, junction boxes and Low

Voltage Nodes

• Fiber and Electrical connections

7

• Power at 5v, 12v, and 24v
• Bandwidth variable
• Just over 100 Core Sensors of 30 types

Concept of Operations

• RSN Operations processes are based on the

Telecommunications Operations Model (TOM)

• Provides a network to services hierachy
• Connecting the Sensors to the Cyber

8

• Connecting the Sensors to the Cyber

Infrastructure = RSN Service

• Availability of the Primary Infrastructure =

99.5% and less than 2 ship repairs in 25 years.

Maintenance Requirements & Strategies

• Primary versus Secondary Infrastructure
• Primary (vs telecom)

–Identical route planning and installation quality –Cable ship, jointing, maintenance processes

10

–Cable ship, jointing, maintenance processes –Lower availability –Maintenance Funding risk

Maintenance Requirements & Strategies

• Secondary versus Primary

–UNOLS vessel + ROVs –Higher risk planned –Lower Availability

11

–Lower Availability –Sensor calibration –Sample recovery –Replacement

Market Growth

• Current

–Cabled Observatories exist in five countries

• Planning

12

• Planning

–Nine or ten countries planning

• Thousands of Kilometers coming

Summary

• There are already a number of Cabled Observatories
• Expectations are for significant global growth
• Cable maintenance needs are compatible

–Reliability vs Cost
