2Wire products make Nessum-Wire integration easier and more cost-efficient

The new 2Wire Converter 6th Generation is fully based on Power-over-Ethernet (PoE) and supports all common standards — from classic PoE to the latest PoE++ (IEEE 802.3bt) with up to 90 W input power. On the 2-wire bus side, end devices are supplied with up to 30 W per PoE+ standard (IEEE 802.3at). The devices are fully bus-capable: in addition to the PD master, up to 128 PSE terminals (nodes) can be operated on the bus. As with all Nessum-Wire products, a range of up to 1,000 m at up to 95 Mbit/s net data rate is achieved. With the optionally available multi-hop method, up to 1,024 terminals at ranges of up to 10 km are possible — ideal for large-scale campus installations, industrial facilities, or infrastructure projects.

The new 2Wire module makes integrating Nessum-Wire into proprietary products even easier and more cost-efficient. The compact module is soldered onto the target hardware like a standard component and functions either as a PHY for an existing Ethernet MAC or as a complete MAC. All Nessum-specific functions are encapsulated within the module, allowing developers to focus on their core application.
The integrated shielding housing provides additional robustness against electromagnetic interference and mechanical influences. Connectivity is flexible across a wide range of media — from powerline and dedicated cables to coax lines.

The advantages of Nessum-Wire technology — formerly known as HD-PLC and standardized as IEEE 1901 — become particularly evident in comparison with Single Pair Ethernet (SPE).

 
Challenges with SPE:
• Fragmentation into three incompatible standards (10BASE-T1L, 100BASE-T1,
1000BASE-T1)
• Exclusively point-to-point connections — each node requires a switch
• Limited range at higher data rates (15–40 m at Gigabit)

 
Nessum-Wire advantages:
• A single unified standard for all applications
• 95 Mbit/s over up to 1,000 m, with multi-hop up to 10 km
• True bus topology: up to 128 or 1,024 nodes on the same 2-wire bus
• Significant cost savings by eliminating switches for large numbers of sensors and actuators
• Ability to reuse existing 2-wire infrastructure

Especially in building automation with hundreds of IoT sensors, actuators, and controllers plus selected IP cameras, Nessum-Wire offers an unbeatable price-toperformance ratio.

With these two new additions, adatec’s Nessum-based 2Wire ecosystem continues to grow with products that all communicate seamlessly with each other and are powered via the 2-wire bus. The modular system enables scalable solutions with a unified technology — from a single sensor to complex campus installations.
