Скачать или смотреть Ethernet Splitter Explained: How to Use for CCTV Cameras (Step-by-Step) & Save Cable!

The *Ethernet cable splitter* you're describing (like the *AD-UTP-2W/2G* or *PULSAR P-POE2**) is a **passive* device that allows two network devices to share a single Ethernet cable by splitting the *4 pairs* of wires in a Cat5e/Cat6 cable into two separate *10/100 Mbps* connections.

*How It Works:*
A standard Ethernet cable has *8 wires* (4 pairs), but *10/100 Mbps* connections only use *2 pairs* (4 wires).
The splitter *divides* the cable:
*Port 1 (LAN1/Gigabit)**: Uses **2 pairs* (typically Orange & Green wires).
*Port 2 (LAN2/Gigabit)**: Uses the other **2 pairs* (typically Blue & Brown wires).
This allows *two 100 Mbps devices* to share one cable without needing a switch.

*Key Features & Limitations:*
✔ *Supports 10/100 Mbps* (not Gigabit, as Gigabit uses all 4 pairs).
✔ **PoE-Compatible**: Can carry power to devices like IP cameras (if the splitter supports PoE passthrough).
✔ *Distance**: Works up to **100m* (standard Ethernet limit), but with high-quality cable & PoE, some extend to **300m**.
✔ **Use Cases**:
*CCTV/IP cameras* (two cameras over one cable).
*Low-bandwidth devices* (printers, sensors, access points).

❌ *Not for high-speed or simultaneous traffic* (since it's not a switch).
❌ *No signal amplification* (unlike an active splitter or switch).

*Alternative Solutions:*
*For Gigabit speeds**: Use a **small Ethernet switch* (active splitting).
*For PoE cameras**: A **PoE switch* or *PoE injector* is better for multiple devices.
