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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
The Difference Between a Hub and a Router
For someone who needs a quick clarification on the matter, a hub combines all linked
computers or workstations into a network, while router links two separate and distinct
networks to each other. 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 ...
Hubs, Switches and Routers - What's the Difference?
The terms "hub", "switch", and "router" are often used interchangeably and - in fact, the
devices are quite different. Hubs are used to simply interconnect individual computers.
Switches do the same more efficiently. However, routers interconnect different networks
(as opposed to individual machines). 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 ...
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 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 ...
