How to Set up a Private Network
A private network is one which does not connect directly to the internet, but does allow you to connect to other computers that are on the same physical network. More ...
MPO Connector, MTP Connector, What's the Difference?
MPO stands for Multi-fibre Push On and is a fiber optic connector type. MTP is a registered trademark of US Conec. The MTP design complies with the MPO standard. More ...
LAN Network Protocols - Ethernet, STP, Fiber
Spanning Tree is an algorithm that runs on Layer 2 campus switches for preventing Layer 2 loops and broadcast storms on a network with at least 2 switches or bridges. The algorithm determines what ports at each switch or bridge must be blocked to create a loop free topology. 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 ...
Computer Networking Devices
Computer networking devices, also known as networking hardware or network equipment are components connected to the network by network media. This article describes the function of the hub, bridge, switch, router, gateway, multilayer switch, and brouter. More ...
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 ...
Ethernet Bridges
Unlike a hub, which blindly forwards received bits, a bridge makes intelligent forwarding decisions based on the destination MAC address in a frame. More ...
Bluetooth Basics
Bluetooth wireless technology is a specification for a wireless connection that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. More ...
A Guide to Broadband Internet Connections
By this point, most of America already has a Broadband Connection to the Internet. But for those that have not yet taken the plunge, a world of benefits awaits you. Broadband can get you surfing up to 50 times faster than a typical 56K modem. 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 ...
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 ...
Troubleshooting Your Optical Fiber Networks - Introduction to OTDR
In fiber optic networks, OTDR (Optical Time Domain Reflectometer) is an opto-electronic instrument used to characterize an optical fiber. An OTDR may be used for estimating the fiber's length and overall attenuation, including splice and mated-connector losses. It may also be used to locate faults, such as breaks. 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 ...
