A Gigabit Ethernet switch is a network switch whose wired ports support a nominal link rate of up to 1 gigabit per second (1,000 Mbps). It connects wired devices such as computers, printers, and access points into one local network and forwards traffic between them. The port speed is only the starting point: ports, management features, power over Ethernet, and uplink options vary widely from model to model.
What “gigabit” means in practice
“Gigabit” describes the link rate of each port, not the performance of the whole network. On copper ports, the rate is standardized as 1000BASE-T. Cisco’s 110 Series datasheet identifies 1000BASE-T with IEEE 802.3ab and lists 10/100/1000 Ethernet ports, which means the same port can run at slower rates when it connects to older equipment.
The term does not mean any of the following:
- Your internet connection is one gigabit. The switch only handles traffic inside your local network. Your internet speed is set by your service plan and modem or router.
- A file transfer will sustain 1 Gbps. Each device, its cable, its network card, and the storage at both ends must also support the speed. Manufacturer datasheets establish port rates, not application-level throughput.
- The switch has any particular feature set. A gigabit switch can be unmanaged or managed, can supply power to devices, and can have fiber uplinks, but none of these is implied by the speed rating.
What a Gigabit Ethernet switch does on a network
A switch gives several wired Ethernet endpoints a way to communicate with one another. Devices plug into its RJ-45 ports, and the switch forwards each frame to the port where the destination device is connected. A common use is adding wired ports near a router, so that a desk, media player, or home office computer can connect without a cable running back to the router’s own ports.
Cisco describes its 110 Series, a small-business product line, in these words: “Cisco 110 Series switches work right out of the box, with no software to install and nothing to configure.” That statement applies to Cisco’s 110 Series unmanaged products. It is not a description of managed switches, and TP-Link similarly describes its cited desktop model as requiring no configuration.

Features that change what you buy
Port count
Choose enough ports for the devices you plan to connect, and remember that one port may be used to link the switch to a router or to another switch. Manufacturer product ranges include unmanaged models with 5, 8, 16, and 24 gigabit ports; D-Link’s DGS-1000 series non-PoE comparison table lists these counts. Leave spare ports if you expect to add devices.
Management
Unmanaged switches are designed to run without setup, which is the case for the cited Cisco 110 Series and TP-Link examples. Managed switches add configuration and controls. Cisco’s Catalyst datasheet lists VLAN, spanning-tree, authentication, and monitoring-related standards and features for that product line. Choose a managed model only if you need those controls, because they add setup work.

Cabling and distance
For copper gigabit equipment, the specified maximum run is 100 m. The cable category required is stated differently across manufacturers, so check the datasheet for the exact switch you buy:

Power over Ethernet (PoE)
A PoE switch can deliver power to compatible endpoints such as IP cameras, phones, or wireless access points through the same Ethernet cable. Four things determine whether it fits your setup: the supported IEEE PoE standard, which ports supply power, the per-port output, and the total power budget. TP-Link’s TL-SG1008P V3 is an 8-port desktop switch with four PoE ports and a 55 W total budget. Cisco’s Catalyst guide lists output ranges that depend on the model, so no single figure applies to all PoE switches.
Uplinks
Some models include SFP slots that accept fiber or copper transceivers. Cisco’s Catalyst 1000 guide documents 1G SFP module slots as uplink interfaces. A switch and a transceiver must be compatible with each other, so confirm the supported module types in the switch’s documentation before buying one.

Form factor and noise
Desktop models sit on a shelf or desk, while other models are designed for racks. Fan presence and noise differ between models. TP-Link’s desktop example is fanless, which matters if the switch sits in a bedroom or office.

Choosing a model: which features matter for which setup
- A few wired computers near a router: an unmanaged gigabit switch with spare ports is usually enough, and no configuration is required.
- Powering cameras, phones, or access points: choose a PoE model, then check that the total budget covers the combined draw of every device, not just the number of PoE ports.
- Separating traffic or monitoring the network: a managed model is needed for features such as VLANs and monitoring.
- Connecting one switch to another across a distance or to fiber: confirm that the switch has SFP uplink slots and that the transceiver type is supported.
- Installing in a quiet space: compare fan and noise information in the datasheet, since models differ.
What the published specifications establish, and what they do not
The figures in this article come from manufacturer materials: Cisco, D-Link, and TP-Link product pages and datasheets. They describe specific models and are not independent test results. No independent or market-level statistic about Gigabit Ethernet switches was found in these sources, so the numbers here should be read as product specifications only.
Product specifications, product availability, and model lineups change over time. Before you buy, check the current datasheet for the exact model, particularly its PoE budget, cable requirements, and uplink types.
The IEEE standard named here (802.3ab for 1000BASE-T) is cited as the manufacturers present it. The standard document itself was not reviewed for this article.
