This document outlines the course objectives, target audience, and content of a five-day course on optical communication and fiber optic networks. The course aims to introduce participants to optical communication principles and various fiber access and transport network technologies. It will provide an understanding of access network architectures, WDM technologies, DWDM network components and operations. The target audience is technical staff involved in optical fiber network design, operation, maintenance and management. The course content includes topics on optical communication fundamentals, different access network solutions, DWDM networks, transmission effects and mitigation techniques.

1. This five-day course is designed to introduce the participant to principles of optical communication
along with the application of optical fiber in optical fibre access networks and optical transport/trans-
mission networks with details on different options available to build them and factors to consider when
building them.

COURSE TRAINERS
Who we are
The CTO is the oldest and largest Commonwealth organisation engaged in multilateral
collaboration in the field of ICTs. Using in-house and partner experience, it supports
members in integrating ICTs to deliver effective development interventions that
emancipate, enrich, equalise and empower people within the Commonwealth and
beyond.
What we do
The work of the CTO goes back to the Organisation’s creation in 1901 as the Pacific
Cable Board. Since then, the CTO has been at the centre of continuous and extensive
international communications development funding, cooperation and assistance
programmes. Since 1985, the Organisation has delivered to its members in Europe, the
Caribbean, the Americas, Africa and Asia-Pacific over 3,760 bilateral and multilateral
telecommunications and ICT capacity building projects in the form of policy, operational
and regulatory training, and expert assistance. Moreover, the CTO has been at the
forefront of generating cutting-edge knowledge through its research and consultancy
services, as well as sharing ideas through its conferences and workshops held around
the world. This long history as a development facilitator provides the Organisation with a
unique and growing delivery capacity for ICT4D programmes and services.
Supporting ICT4D in the Commonwealth
The CTO seeks to work collaboratively with other Commonwealth bodies to build
mutually beneficial synergies in the interests of its members. The CTO has a key role
to play in leading ICT4D initiatives across the Commonwealth, and it is committed to
working together with other Commonwealth entities to reduce overlap and replication
of activities. The CTO welcomes the opportunity to offer secretariat support to any
Commonwealth ICT initiatives that reflect the needs and interests of its members.
