Let There Be Light!

August 8, 2010

Have you ever read the Bible?

Gen 1:3 “And God said, Let there be light: and there was light.”.

Did you notice as you continued to read that it wasn’t till the fourth day that the stars and sun and moon came into existence? So what light was God talking about in Gen 1:3?

Well according to John 1:1 and Heb 11:3 and 2 Peter 3:5 it is God’s Word.

God’s light is his thoughts and images.

 The great combination of thoughts and images transmitted by light  has been the Holy Grail that has been sought after since the first computers were connected. Obviously it was God’s idea first. 🙂

Why?  Because there is nothing faster than light!

Now that the new processors spend most of their time waiting for the data to proccess, the need to get the data to them faster is crucial. The year that light enters the computer as an interface is 2011!  It is this coming year that copper will begin to be replaced with a new fiber optic interface, designed by Intel Corp, which is called Light Peak!

I know what your thinking, fiber optic cable travels at 2 gigabyte so not a big deal, right? Well this design adaptation begins at 10 gigabytes and can easily go to 100 gigabytes.  

Imagine downloading a blueray movie in less than 30 seconds!   Imagine only one cable connecting your computer to your high definition monitor, then to your then TV, then it connects to your printer, then another computer, then….  There is no limit to the amount of connections and different data types, and the cable is 1/3 the size of  aquarium air tubing.

Instead of hundreds or thousands of wires for differnet signals and data there is only one!

With existing servers and the internet how much of the cabling is copper wiring?  What will this do to the internet and communications industry?

With aircraft how much of the weight is copper cabling ?  What will this do to the aircraft industry?

With robotics, how much of the robot is copper wire? What will this do to the robotics industry?

In the begining God brought forth his images, thoughts and words as light and created the world we have now.

Now man will  bring forth his thoughts, words and images as light and the world’s change will begin.

Home Office Network Nightmare

April 28, 2009

463px-the_screamI can see in my mind the Quality assurance inspectors at the network cable manufacturing plants testing the cables while a signal is passing through it.
(Warning the following technical information maybe a little mind numbing) 🙂
Quality check of standard Unshielded Twisted Pair (UTP) non plenum network cable.

Operating temperature range -20°C , 80°C ;check.
DB check for noise at high frequency; check good
DB check for crosstalk at high frequency; check good
Maximum pull tension before signal degradation 35 lbs ; check good
Maximum bend radius before signal degradation 4 ” ; check good
Maximum length before signal degradation 250 feet; check good
(end of mind numbing technical info) 🙂
Little do the inspectors and manufacturers know that their testing is not enough.They do not know the tortures that await the cable once they are installed in a home.
What are they missing?
troubleshooting01 A pit bull or terrier chew test.
You see dogs never chew on cable that is out in the open they chew on the cable under the desk; behind the curtain or any other place that you can not see.

Then there should the 120 to 200 lbs Foot Step Crunch testThis test will see if the the finitely placed twists to the cable, to resist crosstalk and noise, will go back in place after being repeatedly crunched by an adult human foot stepping on it.
It works for a cockroach doesn’t it? 🙂

What should follow next is the I didn’t see the cable that tripped me test.This should be done at least twice to simulate a real home office environment. The Quality Assurance test will verify if there are sufficient strands left in the RJ45 connector to carry a signal after the majority of the strands were ripped out by the forceful kick of a 150 lbs adult having slightly exceeded the 35 lbs pull tension limit of the cables specifications.

What’s next? The Slinky testThis is where the house keeper, mom or family member thinks it will be more tidy if the excess cable was coiled into a tight little slinky. The test should verify that the slinky coiled network cable will not blowout the network interface card in the computer or the port in the switch, modem or router. Remember when you made a magnet with a nail and wire coiled around it? Even though there is no nail the magnetic field is there and pushes the current the other way. So even though there is no nail in the coil the router port or switch port or modem port gets nailed. 🙂

Next there should be the Hoover test where a loop of the network cable is caught in a vacuum cleaner for 8 to ten seconds just enough time for the bristles to tear away the insulation and expose the wires. Hey this one really sucks 🙂

Finally there should be a test to verify that the laws of physics still work and should be posted on the cables. What test is this?
The 250 foot limit!At 250 feet the frequency changes; its called the Doppler effect. What is amazing to me is that people still put extensions on the end to get an extra 3 or more feet and it doesn’t work. They always respond “Then why do they make the extensions?” The answer is so people will buy them! The only way to add any footage to the limit is to add a four port network switch with power.

But as with all nightmares they come to an end and I always tell myself it could be worse. It could have been a wireless network! 🙂
