Most data cabling companies face a choice of two distinctly different business development paths. Some spend most of their marketing, sales, and business development resources pursuing large major bid opportunities with Fortune 1000 enterprises and government entities. Other data cabling companies do a lot more in the small business space, where installations typically involve networks of anywhere from 10-100 nodes. However it can be very difficult to profitably market to customers that really only need your services once... with perhaps some small add-on work a few years down the road. This is because your customer acquisition costs can be quite high relative to the rather limited size of the job...

rror ratio (BER) measurement is the fundamental measurement of the quality of the fiber optic communication system. It measures the system's probability that transmitted bits will be correctly received as logic ones and zeros. Bit error ratio is the ratio of the number of bits received incorrectly compared to the number of bits transmitted in a specified time interval or quantity of bits. The typical acceptable BER levels range from 1e-9 to 1e-12. Equipment for testing BER The equipment used to test a fiber optic system's BER is called BERT (bit error ratio tester). BERT has two fundamental parts: a signal pattern generator and an error detector. What is a signal pattern generator and how does it...

When you finish your basement or finish that garage off you will be happy that you put that 3-way switch in instead of a single switch. To get started you have to have one of the switches and your ohm meter. Make sure the meter is set to ohms. It may just have a symbol that looks like a fat horseshoe to mark ohms. You need to find the common lead(screw). The common is sometimes but not always indicated by a different color screw. Take your...
