Description
This unit describes the skills and knowledge required to design a high capacity, dense wavelength division, multiplexing (DWDM) optical network suitable for a metropolitan area network (MAN) and long-haul applications.It applies to individuals who are skilled technicians and excellent communicators who use optical technologies for the deployment of high capacity networks. The work involves link budget design and providing specification details for configuration and commissioning teams.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Prepare to design DWDM systems
  • 1.1 Obtain and review planning documents, required legislation, codes, company work practices, regulations and standards, work health and safety (WHS) and environmental requirements, personal protective equipment, and hazard identification tools for scoped work
  • 1.2 Obtain the service type and number of channels required between customer traffic sources, destinations and the type of required protection
  • 1.3 Obtain specifications of optical fibre between sites
  • 1.4 Determine fibre loss between sites
2. Calculate link budget for each wavelength path for DWDM system design
  • 2.1 Calculate link budget and link margin for each DWDM wavelength and path
  • 2.2 Evaluate link budget, assess calculated margin and make recommendations for improvements
  • 2.3 Analyse specifications of installed optical fibre and determine if dispersion will limit the maximum traffic data rate
  • 2.4 Generate options for system design that are realistic for the enterprise and network
  • 2.5 Evaluate and select preferred option in consideration of enterprise business strategy outcomes, service policy and compliance with required legislation
  • 2.6 Discuss and confirm selected option with customer
3. Prepare detailed configuration documents for DWDM system
  • 3.1 Outline detailed requirements of the DWDM system for configuration document
  • 3.2 Document the DWDM systems performance, functional and physical attributes according to the customers traffic needs
  • 3.3 Prepare an internet protocol (IP) address allocation for all DWDM shelves and associated routers and gateways
  • 3.4 Submit documentation to relevant personnel for approval and sign off
4. Investigate upgrade options with emerging technologies
  • 4.1 Investigate option of using a reconfigurable optical add-drop multiplexer (ROADM) and make recommendations, outlining benefits
  • 4.2 Investigate feasibility of a future upgrade up to 100 Gbps system using optical transport network (OTN) - DWDM technology
