Overview of IEEE 802.11 Wireless Lan Technology
Wireless LAN (WLAN) is a wireless broadband technology that utilizes radio frequency (RF) to transmit and receive data through the air There are two competing RF technologies in the use of Wireless LAN, the IEEE 802.11 standard and proprietary technologies. Both fall under wireless broadband technology. 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 are OFNP, OFNR, OFNG and OFCG? Understanding Fiber Optic Cable Fire Ratings
Just like copper cables, NEC (National Electrical Code) requires indoor fiber optic cables be marked with their fire and smoking ratings. According to NEC, a building's inside area is divided into three types of sections: plenums, risers and general purpose areas. More ...
What Are Pseudo-Wires?
Pseudo-wire is a mechanism used in networking and telecommunications to emulate various services using packet switched networks with technologies such as Ethernet, MPLS (Multi Protocol Labelled Switching) and IP (Internet Protocol). 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 ...
The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE). The IEEE sets up committees to define industry standards. The IEEE 802 committee sets the standards for networking. The IEEE subcommittee 802.3 sets the standard for Ethernet. 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 ...
Wireless Networking Infrastructure Mode
In Ad Hoc mode devices make wireless connections directly between computers, Infrastructure mode wireless devices use access points (WAPs), switches, and routers to connect. 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 ...
Six Things You Must Know About Fiber Optic Cable Materials
Outdoor fiber cables must endure harsh environment factors so outdoor cables must be strong, weatherproof and UV resistant. Indoor fiber cables should possess NEC required fire and smoke ratings. More ...
How to Choose the Proper Fiber Optic Connector for Your FTTH (Fiber To The Home) Installation
Fiber optic connectors can be divided into three groups: simplex, duplex and multiple fiber connectors. Simplex connector means only one fiber is terminated in the connector. Duplex connector means two fibers are terminated in the connector. More ...
Wireless Network Vlans - How to Implement Wireless Vlans
Wireless access points operate as bridges with no routing defined anywhere on the wireless network segment. VLANs are defined on the wired switches and mapped with specific SSIDs at each access point. The wireless client associates with a specific SSID which in turn will map client with membership in a specific VLAN. More ...
Data Center Networking
In recent years, companies such as Amazon, Google, and Microsoft have built massive data centers, each housing tens to hundreds of thousands of hosts, and concurrently supporting many distinct cloud applications. Each data center has its own data center network that interconnects its hosts and interconnects the data center with the Internet. More ...
