Build Your Own Fiber Optic Network Like a Professional Network Engineer
The basic philosophy of modern LAN wiring is the concept of structured cabling. The entire networking system is broken up into chunks that allow workstation wires to be concentrated. More ...
How In-Row Cooling Increases Data Center Efficiency
Increased data center densities enable operators to meet the demands of cloud and hyper-scale environments. As more power is consumed per rack, however, heat becomes a big problem. Most modern data centers have adopted some sort of aisle-containment solution to minimize the mixing of hot and cold air. More ...
Wireless or Wired Network?
Do you want the freedom of a wireless network, or do you want the security and reliability of a wired network? Both networks can provide you with great service and expandability, but each one varies in size, reliability, cost and speed. More ...
Cisco Switching Fundamentals
Newer switches now use ASICs (Application Specific Integrated Circuits) for high speed hardware switching of packets. This results in much faster performance than packets processed in software. 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 ...
Difference Between Unmanaged, Web Smart and Managed Switch
A network switch is used to route data over a communication network. There are four major types of a switches. It can either be an unmanaged switch, a managed switch, a smart switch or an enterprise managed switch. Each kind of switch has its own strengths and weaknesses. More ...
Introduction to SONET (Synchronous Optical Networking)
SONET (Synchronous Optical Networking) standards were developed to take advantage of low-cost transmission over optical fibers. It defines a hierarchy of data rates, formats and optical signal specifications. More ...
Trunking, Bonding, Aggregation; What Does it Mean?
Each port on a network switch would be connected to one network device, such as a computer. But to connect a server you need higher bandwidth. For this purpose you could combine multiple Ethernet channels into one. More ...
Token Ring Network
In 1984 IBM invented Token Ring. The token ring network may be setup with a physical ring topology, but is usually implemented in a physical star topology. The central device of the token ring is called a Multistation Access Unit. More ...
What Are Fiber Optic Isolators?
Light can be reflected back and forth. In fiber optic networks, the reflections are harmful to the system. That's where fiber optic isolator comes to play. Optical isolators stop
back-reflection. 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 ...
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 ...
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 ...
