Chapter 2. Installation
10BaseT
: uses a twisted pair cable of up to 100 meters in length between a node and another node, switch,
hub, or repeater. 10Mbs may be used for the Command Line Interface (CLI) and general Ethernet traffic, but
not for PROFINET communications.
100BaseTX
: uses a cable of up to 100 meters in length between a node and another node, switch, hub, or
repeater. The cable should be data grade Category 5 or better unshielded twisted pair (UTP) or shielded
twisted pair (STP).
1000BaseT
: uses a cable of up to 100 meters in length between a node and another node, switch, hub, or
repeater. The cable should be data grade Category 5 or better shielded cable.
2.7.2.1 Network Cabling and Connector Types
Copper: up to 100 Meters between Devices
All Automation & Controls products from GE Energy Connections use RJ45 connectors for copper connections.
Copper cabling and connections are easily available in the general market and support distances of up to
100m.

Figure 22: Interconnect using Copper Cables / RJ45 Connectors

Multi-Mode Fiber: up to 2 km between Devices
Multi-Mode Fiber supports two types of connectors, LC and SC. The LC connector is used on SFPs on the RX3i
PNC001 and on the PNS modules. The SC connector is used on the VersaMax PNS. Cables are available with
LC-to-LC connectors and LC-to-SC connectors to match the different connector formats. Multi-Mode fiber can
support distances up to 2Km at 100Mbps. When using fiber, pay particular attention to the cable connector
and cable radius clearance requirements in cabinet planning and layout.

Figure 23: Interconnect using Multi-Mode Fiber

Single-Mode Fiber: up to 70 km between Devices
Single-Mode Fiber is supported between SFPs using the LC connector. Single-Mode fiber can support distances
up to 70 km. As with the Multi-mode fiber, pay attention to the cable connector, radius, and minimum length
requirements in planning the installation.
