About Shielded Twisted Pair (STP)

Written by Julianus Yu

Shielded twisted-pair (STP) cabling was first made popular by IBM when it introduced Type classification for data cabling. Though more expensive to purchase and install than UTP, STP offers some distinct advantages. The current ANSI/TIA/EIA-568-B Cabling Standard recognizes IBM Type 1A horizontal cable, which supports frequency rates of up to 300MHz, but does not recommend it for new installations. STP cable is less susceptible to outside electromagnetic interference (EMI) than UTP cabling because all cable pairs are well shielded.

All Kind Of UTP Cable Ever Been Created

Written by Julianus Yu

Though two cables may look identical, their supported data rates can be dramatically different. Older UTP cables that were installed to support telephone systems may not even support 10Base-T Ethernet. The ANSI/TIA/EIA-568-B Standard helps consumers choose the right cable (and components) for the right application. The Standard has been updated over the years and currently defines four categories of UTP cable: Categories 3, 5, 5e, and 6. Note that Category 5 requirements have been moved to an addendum and are not officially recognized as an approved cable for new installations. Here is a brief rundown of Categories past and present:

About Unshielded Twisted Pair (UTP)

Written by Julianus Yu

unshielded twisted pair (UTP) for LANs first became common in the late 1980s with the advent of Ethernet over twisted-pair wiring and the 10Base-T standard. UTP is cost effective and simple to install, and its bandwidth capabilities are continually being improved.

Advantages Of Using Fiber-Optic Cable

Written by Julianus Yu

Fiber versus fibre: Are these the same? Yes, just as color (U.S. spelling) and colour (British spelling) are the same.

Although for most of us fiber to the desktop is not yet a practical reality, fiber-optic cable is touted as the ultimate answer to all our voice, video, and data transmission needs and continues to make inroads in the LAN market. Some distinct advantages of fiber-optic cable include:

Which Type Of Cable That You Should Chose For Your Horizontal Wiring?

Written by Julianus Yu

Should You Choose Unshielded, Shielded, Screened, or Optical-Fiber Cable for Your Horizontal Wiring?

Many network managers and cabling-infrastructure systems designers face the question of which cabling to choose. Often the decision is very cut and dried, but sometimes it is not. For typical office environments, UTP cable will be always be the best choice (at least until fiber-network components drop in price). Most offices don’t experience anywhere near the amount of electromagnetic interference necessary to justify the additional expense of installing shielded twisted-pair cabling.

Major Types Cabling For Communication Media

Written by Julianus Yu

Four major types of communications media (cabling) are available for data networking today:unshielded twisted pair (UTP), shielded or screened twisted pair (STP or ScTP), coaxial, and fiber optic (FO). It is important to distinguish between backbone cables and horizontal cables. Backbone cables connect network equipment such as servers, switches, and routers and connect equipment rooms and communication closets. Horizontal cables run from the communication closets to the wall outlets.

What We Should Know About Data Center

Written by Julianus Yu

A data center or datacenter (or datacentre), also called a server farm,is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices.

The Power Of Content Management System

Written by Julianus Yu

In to day Fast paced world of internet, if you have a website that doesn't have rich functionality or fresh content, you will find yourself at a disadvantage to those that do. The idea of powering websites with content management system-CMS has been around some time,but it is only recently, with the advent of high quality open source CMS script like Joomla, that you and I can now use these powerful CMS tools.

Let's take a look at the historical development of web pages, Conceptually there are two aspects to a web page: it's content and the presentation of the content. Over the last decade, there has been an evolution of how these two pieces interact :
