Let Curt Carlson, esteemed Product Manager at Transition Networks, talk you through another FREE self-paced, networking training seminar.

Networking Basics for Cable Installers and Electrical Contractors was originally designed for Cabling Installers and Electrical Contractors. However, the overall intent of the presentation is to give those who might be relatively new to data communications, a basic understanding of what makes up a typical network. Which means, anyone who is interested in the topic is welcome to take advantage of this FREE self-paced seminar.

More and more products are being released with single mode single fiber optics and can be perceived as being very expensive, but are they?

What is single mode single fiber?
The answer is that it is possible to transmit and receive using one strand of single mode fiber. This is achieved by using two different wavelengths - one end will transmit at 1550 and will receive at 1310 and vice versa for the other end. By using these wavelengths the signals will never collide.

Fiber Optics has only widely been implemented over the last 20 years, although the technology, ideas and concepts have been around for much longer. Optical communication systems starting with Claude Chappe’s invention of the “optical telegraph” in the 1790’s has been in use for more than 200 years. Or more recently, in 1930 a German medical student named Heinrich Lamm - was the first person to assemble a bundle of optical fibers to carry a recognizable image. Lamm’s invention was developed to look inside inaccessible parts of the human body. Although, this discovery was not entirely as successful as he had hoped it would be, Lamm’s theory of transmitting an image through a “flexible multi-fiber conductor of radiant energy” was still in fact, a great success. continue »

One of the major problems of the introduction of 1000Base (gig) was the distance limitation of 1000base over fiber optic cables. Most users were aware that 10Base and 100base could run over 2km of multimode fiber optic cable and up to 20Km of single mode fiber optic cable - though advancement in components now allows single optics can now achieve distances of 125Km plus. However, with the introduction and deployment of 1000Base networks over fiber optics users found that their fiber cables could not sustain that rate and were effectively useless. continue »

With the large number of trade magazines focusing on information technology and network cabling, I sometimes find it hard to stay caught up on my reading file. For this reason, I always appreciate receiving suggested reading tips from my friends and colleagues on articles that they have found interesting. One of these articles, entitled Fiber-to-the-Desk Takes the Stand, is in the November 2007 issue of Cabling Business Magazine. In this commentary written by Mr. Bob Ballard, he convincingly argues that the myth of fiber installations always being more expensive than copper installations is no longer true. He says that several projects across the country have proven this and in particular he cites a project at the Houston U.S. Federal Courts office. continue »
