This paper presents an overview about WDM technology and recent developments in this field and how the overall capacity of the communication network can be incremented using this technology. Keywords – bandwidth, multiplexing, optical network unit, OCDM, passive. WDM is a technique that enables multiple optical signals to be transmitted over a single fiber optic cable, each at a different wavelength. The application fields of wavelength division multiplexing (WDM) integrated devices are continually expanding.

Papua New Guinea is enhancing its digital infrastructure through an extensive National Transmission Network. PNG DataCo, a subsidiary of Kumul Consolidated Holdings, operates the NTN, which spans over 12,000 km of fibre cable. As telecommunications connectivity reaches 80 per cent of Papua New Guinea's population, Business Advantage PNG looks at how the country's telecommunications wholesaler, PNG DataCo, is working to encourage greater adoption of the internet by business and consumers. Papua New Guinea's internet system continues to rely heavily on fibre optic cables, despite the growing presence of satellite-based services across the country, according to PNG DataCo. Work is underway to lay high speed telecommunication cables from Australia to Papua New Guinea and Solomon Islands, including a domestic network connecting Honiara with Auki, Taro and Noro. The Coral Sea Cable System (CS 2) will deliver faster, cheaper and more reliable communications. In addition, DataCo manages three tied data centers and 51 satellite infrastructures throughout Papua New Guinea (PNG).
