Product Information

That gives you fast connectivity for two devices (or more if using an adapter) with only one intervening cable, making it much easier to set up and install, and it keeps cable clutter to a minimum. What is Ethernet splitter? MiniTool provides you with a full introduction here. What Is Ethernet Splitter

To get around that problem, you can use an Ethernet splitter, or rather, an Ethernet switch. These devices can take a singular incoming Ethernet connection and make it accessible to multiple users at the same time. This not only expands the number of available Ethernet connections for waiting devices but makes running the Ethernet cable much easier since you needn’t have multiple cables going around doors and through walls: just run one cable, with a splitter on the end. It's useful to understand what a splitter does. It turns one 8-strand ethernet cable into a what would be, essentially, a pair of sub-standard 4-strand cables that in theory should do Fast Ethernet (100BaseT/TX). Practically this might drop down to 10BaseT speeds, and you need to use a splitter on both ends for it to work. It will take up two ethernet ports on the far end. It will absolutely not work for Gigabit (1000Base) Ethernet, as that requires all 8 strands.

What Ethernet Splitter To Buy? 

You can mitigate this problem by enhancing your network. Using a router that supports 2.5 Gbps, or even 10 Gbps Ethernet is a good start. Pair that with Cat 6 or newer Ethernet cables that support that kind of high-speed networking with adequate shielding to protect the sanctity of your data. Even if you end up splitting that high-speed connection between devices, it’s at least fast enough that no one should feel like they’re missing out by sharing the total throughput.

A splitter works by taking two physical Ethernet ports and sending both connections (which must be limited to using 100mbps speeds) though a single cable. A splitter doesn't connect both ports together in any way. It keeps both ports isolated unlike hubs and switches. NOTE: Don't support 2 computers that connect to the internet simultaneously, ONLY 1 output port is working.

Best CAT5 Ethernet Splitters in 2023

An Ethernet splitter can be thought of a type of device that isn't a hub or a switch. It is a rather simple device that actually does nothing but connect two pairs of 2 Ethernet cables to a single Ethernet cable. If you don't trust Ethernet splitters then you can actually build a cable that does the exact same thing. Ethernet splitters are not mini-hubs. They are specifically designed to split a single connection with four twisted pairs into two connections with two distinct twisted pairs.

It is, however, an ideal solution for expanding network functionality to pre-existing networks where running additional intervening cables is not ideal. It is perfect for situations in which a dedicated connection for each device is required, such as a printer alongside a laptop. T requires only two twisted pairs. So basically half of a Cat 5e cable. Just four out of the eight available wires. So if we’re only using half of the wires in the cable, couldn’t we make one cable act as two cables? Why yes! Yes we can! And that’s exactly what an ethernet splitter does! These clever devices carry two Ethernet connections across a single wire. The sharing kit includes two splitter devices. The splitter consolidates two Ethernet connections into one RJ45 cable, which is then carried to the destination over a single wall plate connection or a coupler. The second splitter un-splits the connection into two Ethernet connectors for two devices.Ethernet couplers are devices used to connect ethernet cable connections from one type to another. There can be various reasons to use a coupler such as to extend network cabling, split a signal allowing for two cables to be connected to a single port or to allow for different network cable types to be connected. Types of Ethernet Couplers Any cable you connect to the splitter will count towards your total cable length. However, since a splitter has 2 physical connections, you have two cable lengths instead of just one. Theoretically, splitters don't amplify signals so your maximum cable length will not be extended. Computer-A could infact be a hub or a switch, but you still have the problem of Computer-B's and Computer-C's TX and RX ports being wired together. Although those two devices do need to share the overall connection speed of the Ethernet cable that runs between the router and the switch, it’s still far more reliable and stable than Wi-Fi which could see the two devices competing for frequency as much as bandwidth.
