This Site is Dedicated to providing information on a number of different Switch types, such as Network Switches, Ethernet Switches, Gigabit Switches, KVM Switches and Optical Switches.

Articles published on this site can be re-published on your site as long as you retain the resource information and link to the relevant website. All articles will eventually be replaced by new article content so as to maintain fresh information for our customers. 

We will also review a number of switch products from various manufacturers and post those reviews on the site.

Ethernet Switch

An Ethernet Switch is designed to connect multiple devices to the network. and to ensure that data is delivered to the correct device. It does this by learning the MAC Addresses connected to each port and building a Port Table, otherwise known as a MAC Address Table so that the location of individual devices are known when Ethernet Frames arrive. An Ethernet Switch was a great advance on its predecessor, the Hub. Modern Ethernet switches have a range of additional features, and we will be discussing some of those features in future articles.

KVM Switch

A KVM Switch  is used to control a number of computer terminals with only a single set of peripherals such as a Keyboard, Mouse and Video Monitor. Special cables have been developed to allow a single DB25 or USB connection at the switch end connect to the various peripherals such as keyboard, video and mouse at the computer end. Most KVM devices have a means of switching control from one PC to another. Future articles will highlight some of the features and innovations associated with modern KVM Switches.

Optical Switch

An Optical Switch is used in Fibre Optic networks to switch data from one optical fibre to another, and a photonic switch is normally used in Telecommunications networks to do just this. Within Passive Optical networks do not use optical switches but passively split a beam of light to forward the same information to all end users within that PON. Passive Optical Networks consist  of OLT (Optical Line Termination) at the Service Provider side and ONU (Optical Network  Unit) at each customer site. Future articles will feature Optical Switches and Passive Optical Networking.
