1.3.1 Composite Fibre Ports
WNS units have up to four composite fibre ports, interconnected by composite cables. The composite
cable contains fibre optic data cores and power (as shown in
Figure 3: WNS composite cable connection ),
and connectors designed for durability in underground mines.

The composite cable overcomes the challenge of limited power access in mines by distributing power
between each WNS in a network. The fibre optic cable contained in the composite cable also provides
the following benefits over standard Ethernet cabling:
• WNS units can be spaced up to several kilometres apart, compared to Ethernet cabling with a distance
limitation of 100 metres. This reduces installation cost, component count and likelihood of faults.
• Fibre optic cable has superior signal integrity, with no signal interference from high powered electronics,
such as variable speed drives.
1.3.2 Ethernet Ports
The WNS has four optional internal Ethernet ports and four external Ethernet ports enabling connection
to client devices or other networking devices.
The four external Ethernet ports also provide IEEE 802.3 af PoE (Power over Ethernet) injector
functionality, allowing a single cable to be used for data and power to network devices. Each Ethernet
port's functionality can be configured by the web browser interface, or by centralised configuration
management. For more information on configuring Ethernet ports, see
Configuring the VLAN Port Map
