Routers
Routers are sometimes confused with network hubs, modems, or network switches. However, routers can also provide additional features such as embedded firewall and content filtering software that provides an additional protection from unwanted content and malicious websites. More ...
Here's a Quick Way to Build Your Fiber Optic Network
What is the most time consuming work in building a fiber network? Two works are usually thelargest line items in an fiber optic network installation budget: pulling the fiber optic cables and terminating or splicing the cables. More ...
Understanding Wireless LAN Networking
Wireless networking allows computers and peripherals to communicate using radio frequency (RF) transmissions rather than over conventional network cabling. Using wireless Ethernet adaptors, any device capable of being used on a regular computer network can be accessed over a wireless connection. More ...
What Are Fiber Optic Circulators?
An optical circulator is an nonreciprocal passive device that directs light sequentially from port to port in only one direction. The operation of a circulator is similar to that of an isolator except its constructions is more complex. More ...
Routing Technologies, Bandwidth Management and Traffic Shaping
Bandwidth is the overshadowing issue for most network quality problems. The response to that problem is often to add more bandwidth. However, more bandwidth often comes at a relativel high cost. More ...
Network Interface Cards (NIC)
Every entity on a network, a PC, printer, router, etc., that needs to communicate with other devices must have a NIC if it is to communicate over the network. NIC functionality is now often integrated into the motherboard chipset or implemented with a dedicated Ethernet chip on the motherboard. More ...
Understanding Optical Fiber Types
Two major types of optical fibers exist for communication systems: multimode and single mode. Multimode fiber can carry many modes of light rays, while single mode fiber can only carry one mode of light ray. More ...
Wireless Networking
If a home has multiple computers, it makes sense for them to share files and an Internet connection. This two-part article will provide an introduction to the basic hardware and security related considerations involved in wireless networking. More ...
How Do Fiber Optic Couplers Work and How are They Made?
Fiber optic couplers are needed for tapping (monitoring the signal quality) or more complex telecommunication systems which require more than simple point-to-point connections, such as ring architectures, bus architectures and star architectures. More ...
What is an Ethernet Switch?
An Ethernet switch is a networking device that is able to interrogate the data within the Ethernet Frames to provide forwarding and filtering and loop avoidance. More ...
Wireless Networks
A wireless LAN (WLAN or WiFi) provides network connectivity by using radio waves rather than cable. Wireless devices can communicate with each other or they can communicate through a wireless access point (WAP) to a wired network. More ...
Access Points and Wireless LAN Controller
An access point is a network device that creates a wireless LAN (WLAN) and might also connect to a wired router to allow wireless devices to connect to the wired LAN. More ...
What Are Fiber Optic Attenuators?
A fiber optic attenuator, also called an optical attenuator, simulates the loss the would be caused by a long length of fiber. For a fiber optic receiver, too much light can overload it and degrade the bit error ratio. More ...
