The Secret of Maintaining Your Fiber Optic Network
During fiber optic network installation, maintenance, or restoration, it is also often necessary
to identify a specific fiber without disrupting live service. This battery powered instrument
looks like a long handheld bar and is called fiber identifier or live fiber identifier. More ...
Static Versus Dynamic Routing
Routers direct traffic between networks or subnetworks. With static routing a network administrator manually
creates the router's routing table. With dynamic routing the router learn about networks use routing protocols
like RIP, RIP2, EIGRP, OSPF, or BGP. 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 ...
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 is an Ethernet Bridge?
Bridges are used to divide larger networks into smaller sections. A bridge reads a
frame's MAC address, and decides to either forward or filte the frame from crossing
the bridge to the other part of the network. More ...
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 ...
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 ...
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 ...
The physical arrangement of the cables, computers and components is referred to as the networks
topology. There are five basic topologies, bus, star, ring, mesh, and wireless. More ...
Understanding Basic Terms in Indoor Fiber Optic Cable Installation
Fiber optic cables are exposed to electrical, mechanical, chemical and environmental elements,
so proper installation is critical for the long-term stability and survival of fiber cables.
Cable installation must also meet the NEC (National Electric Code) and local building codes. 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 ...
Understanding the Basics of All-Optical Switching
All-optical switching is a process by which light in the form of digital communication signals is routed
from one transmission channel to another without intermediate conversion to another format. More ...
