Power and Data Over a Single Ethernet Cable

Milpower Source’s Power over Ethernet (PoE) solutions provide dependable power and data transmission over standard Ethernet cabling, purpose-built for military and aerospace platforms. Engineered to handle multiple power levels and data rates, these products are well-suited for compact equipment such as tactical radios, mission displays, and surveillance systems. All Milpower Source PoE modules comply with MIL-STD requirements, ensuring reliable operation under demanding conditions of shock, vibration, temperature extremes, and EMI. These solutions reduce wiring complexity and enhance system dependability with scalable integration options


What is PoE

Power over Ethernet (PoE) combines data and electrical power delivery into a single Ethernet cable, eliminating separate power wiring. This streamlines system design, lowers installation time and cost, and reduces weight—critical advantages for space-limited military and aerospace systems.

Milpower Source’s PoE products support IEEE 802.3af/at/bt standards, enabling flexible power delivery from 15W to 90W per Ethernet port (10M/100M/1G/10G). Applications include IP cameras, radios, sensors, and wireless access points. By consolidating cabling infrastructure, PoE improves reliability, speeds up deployment, and simplifies integration across mission-critical environments.

Frequently Asked Questions

What is Power over Ethernet (PoE)?

PoE is a technology that delivers both data and electrical power over a single Ethernet cable. This eliminates the need for a separate power line or local power supply, reducing system cost and complexity.

What are PoE PD and PSE?
  • PSE (Power Sourcing Equipment): The device that provides power over Ethernet, such as a PoE switch or injector.
  • PD (Powered Device): The endpoint that receives power—for example, an IP camera, sensor, access point, or radio.
What PoE standards do Milpower Source products support?

Milpower Source’s PoE solutions support:

  • IEEE 802.3af (PoE) – up to 15.4W per port
  • IEEE 802.3at (PoE+) – up to 30W per port
  • IEEE 802.3bt (PoE++) – up to 60–90W per port
What Ethernet speeds are supported with PoE?
  • 802.3af: up to 100 Mbps
  • 802.3at / 802.3bt: up to 10 Gbps
What voltage does PoE use?

PoE typically operates between 44V–57V DC depending on the standard:

  • 802.3af (PoE): ~48–57V
  • 802.3at (PoE+): ~50–57V
  • 802.3bt (PoE++): ~52–57V (supports up to 90W)

The PSE supplies the voltage and safely delivers it to the PD through Ethernet cabling.

What is a PoE Injector?

A PoE injector introduces power into an Ethernet cable for devices connected to a non-PoE switch. Positioned between the switch and the PD, it enables remote powering of cameras, radios, or other equipment.

What is a PoE Splitter?

A PoE splitter separates power and data from a PoE-enabled cable. One output carries Ethernet data (10M/100M/1G/10GBase-T), while the other delivers DC power to non-PoE equipment—ideal for connecting legacy devices to PoE networks.

What is a PoE Budget?

The PoE budget is the total power capacity available from a switch or injector across all active ports. Each connected device draws a portion of this budget, which must remain within the system’s maximum supply.

What are the main advantages of PoE?
  • Simplified installation with one cable per device
  • Lower cost—no local power supply required
  • Energy efficiency through optimized power delivery
  • Scalable and standards-compliant infrastructure
  • Centralized power management for easier load monitoring
