Papua New Guinea Single-Mode Gigabit Fiber Optic Cable

Papua New Guinea's high-speed connectivity is supported by single-mode fiber optic cables through the Coral Sea Cable System and extensive domestic networks operated by PNG DataCo.Submarine Connectivity: Coral Sea Cable System

The Coral Sea Cable System (CS²) is a 4,700 km submarine fiber optic cable linking Sydney, Australia, to Port Moresby, PNG, and Honiara, Solomon Islands . It uses single-mode fiber with Dense Wavelength Division Multiplexing (DWDM) in the 1550nm window, supporting up to 40 Tbps of capacity . The system employs 100G repeaters and ASN's 1620 SOFTNODE Submarine Line Terminal Equipment, providing configurable client interfaces and robust protection against cable faults . CS² ensures faster, more reliable, and cost-effective international connectivity, replacing PNG's aging undersea cable to Sydney .

Domestic Fiber Network

PNG DataCo operates over 12,000 km of fiber optic cable across the country, connecting 44 out of 96 districts via fiber and achieving a 70% district connectivity rate . The network integrates with three data centers and 51 satellite infrastructures, providing low-latency, high-availability services. Single-mode fiber is used extensively for long-distance, high-speed gigabit connections, supporting both wholesale telecommunications and digital services . DataCo also maintains international Points of Presence (PoPs) in Sydney, Guam, Hong Kong, and Jayapura, sourcing upstream IP transit and peering services .

Local Suppliers and Installation

In Port Moresby, suppliers like Cetelnet provide single-mode and multi-mode fiber optic cables suitable for indoor, outdoor, aerial, and underground installations . They offer pre-terminated patch cords, pigtails, splice enclosures, distribution boxes, and installation tools to support professional deployment. Their technical team assists in selecting compatible fiber products for gigabit-speed networks, ensuring signal integrity and durability in PNG's diverse environments .

Benefits and Applications

The deployment of single-mode gigabit fiber in PNG enables:

• High-speed internet access for businesses, government, and communities
• E-governance and digital service delivery
• Support for entrepreneurship and digital skills development
• Integration into global digital markets Overall, PNG's combination of international submarine cables and domestic single-mode fiber networks provides a robust foundation for gigabit-speed connectivity, supporting economic growth and bridging the digital divide.
