A PoE Extender 1 to 2 typically refers to a device that takes a single Power over Ethernet (PoE) input and splits it into two separate outputs, allowing you to power two devices (e.g., IP cameras, access points, or phones) from one PoE-enabled port.

Here's how it works:

• Input: You connect a single PoE Ethernet cable into the device that provides both power and data (like a PoE injector or a PoE switch).
• Output: The device then splits the single PoE signal into two separate Ethernet outputs, each with power and data. These outputs can be used to connect and power two devices.

Some important features you might want to look for:

1. Standard Compliance: Make sure the extender supports standards like IEEE 802.3af (PoE) or IEEE 802.3at (PoE+), depending on the power requirements of your devices.
2. Power Output: Ensure that the extender provides enough power for both devices. For example, PoE+ can deliver up to 25.5 watts per port.
3. Data Speed: Check that the extender supports the necessary data speed (usually 10/100/1000 Mbps) for your devices.

Is this what you're referring to, or were you looking for something else?
