Discover how SPE can enhance your infrastructure with superior performance and significant cost savings.

Modern infrastructure systems, including security, HVAC, and building automation, are increasingly interconnected. As traditional two-wire field buses like LONwork and RS485 are surpassed by Ethernet networks, Single Pair Ethernet (SPE) emerges as a revolutionary solution. SPE extends Ethernet cable lengths up to 1000 meters, eliminating the need for repeaters and offering a game-changing upgrade for Security System Integrators, Pre-Sales Engineers, and Procurement Officers.

 

What is Single Pair Ethernet (SPE)?

Single Pair Ethernet (SPE) enables Ethernet devices to connect over a two-wire (UTP) cable instead of the traditional four-pair CAT5e cable. Governed by the IEEE 802.3cg standard, SPE delivers:

• 10Mbps Full-Duplex Communication: Ideal for high-resolution IP cameras and other bandwidth-intensive applications.
• Power Over the Same Cable (SPoE/PoDL): Simplifies installations by delivering both power and data through a single cable.
• Extended Cable Lengths: Reaches up to 1000 meters, far surpassing traditional Ethernet limitations.

Key Features of SPE:

• 10Base-T1L Protocol: Provides reliable 10Mbps full-duplex communication.
• SPoE (Single Pair Power over Ethernet): Powers remote devices through the same cable, streamlining installation.
• Simple Connections: Utilizes two-pin terminal blocks for easy integration with existing infrastructure.
• Extended Reach: Eliminates the need for costly repeaters with up to 1000 meters of coverage.

Typical SPE Installation: An RJ45 switch port connects to a T1L SPE media converter, which then links via UTP cable to a T1L-compliant remote device. This approach repurposes existing two-wire infrastructure, avoiding the high costs of new cable installations.

Upgrading Existing Two-Wire Buses: Transitioning to Ethernet with SPE allows you to repurpose existing two-wire cables, leveraging Ethernet’s advantages such as noise immunity and error correction, while simplifying power delivery.

Advantages & Cost Savings with SPE:

• Cost-Effective Cabling: Single-pair UTP cables are more affordable than four-pair CAT5e.
• Extended Cable Lengths: Reach up to 1000 meters without needing repeaters.
• Integrated Power Delivery: Reduces the need for separate power supplies.
• Ethernet Benefits: Includes noise immunity, error correction, and encryption.

Cost Savings Breakdown:

1. Reduced Cabling Costs: Single-pair UTP cables are less expensive.
2. Elimination of Repeaters: Saves $100-$500 per repeater.
3. Simplified Installations: Lower labor costs due to fewer components.
4. Lower Power Costs: Centralized power reduces energy consumption.
5. Maintenance & Reliability: Fewer failure points lower maintenance costs by 10-20%.

 

For large installations, these savings can amount to thousands of dollars by avoiding repeaters, reducing cabling and labor costs, and simplifying maintenance.
