Ethernet Splitters vs. Switches: Understanding Network Connectivity Options
Key points
- Passive Ethernet splitters lack hardware for traffic distribution.
- Modern Ethernet cables use four twisted pairs for gigabit speeds.
- Passive splitters utilize only two pairs, limiting speeds to 10/100Mbps.
- Two passive splitters are needed for a single connection to work.
- An Ethernet switch adds more wired ports to a router.
- An Ethernet switch is a plug-and-play device.
- A single switch can add four, seven, or 15+ ports.
Understanding Ethernet Connectivity
Connecting multiple devices to a single Ethernet cable often leads users to consider either an Ethernet splitter or a network switch. The choice between these two options depends on the specific networking needs and the desired performance.
Passive Ethernet Splitters Explained
Passive Ethernet splitters are simple devices without internal hardware for distributing network traffic. They function by re-arranging the wiring within an Ethernet cable. Standard Cat5e or better cables contain four twisted pairs of wires. Passive splitters divide these into two separate two-pair connections, each with an RJ45 port.
This design limits passive splitters to older Ethernet standards, supporting only 10Mbps or 100Mbps connections, as these speeds only require two twisted pairs. Modern gigabit Ethernet connections utilize all four pairs.
Drawbacks of Passive Splitters
Passive Ethernet splitters have two main disadvantages. Firstly, they restrict network speeds to a maximum of 100Mbps. Secondly, a functional setup requires two splitters: one at the router's LAN port and another at the device end. A single splitter cannot enable communication between a router and two devices simultaneously, as the router is not designed to handle the re-arranged wiring from a single splitter.

How outlets covered it
This article explains that an Ethernet switch can add more wired ports to a router, addressing the common issue of insufficient ports for multiple devices. This solution allows users to maintain better, more consistent wired network performance for activities like gaming and 4K streaming without replacing their router.
The article explains the differences between Ethernet splitters and switches, detailing how passive splitters work and why they are generally not recommended for modern network setups. It clarifies that passive splitters only support older, slower Ethernet standards and require two units to function.
