Maximum Operating Frequency and Category Requirements in Cat 3 – 7
With many variables in play, it can be very trick to know what to do, and what not to do when you work with network cables and design. To work through all the possible permutations, it would help if we could find a way to only change one variable at a time. This can easily be achieved if we use the
Read article →Technical articleFiber Connector Installation Methods – Epoxy Method
There are many different methods that can be used to install connectors for fiber optics. The methods were developed over time for different reasons, including convenience, reliability, installation cost and installation time. By far the biggest focus has been on reducing one or more cost factor.
Read article →Technical articleEverything you need to know about decibels
One dB (decibel) really makes a huge difference! Why such terms decibels are used? When you compare cable performance and a manufacturer states that the attenuation (power loss) for a cable operating at 100MHz, with a length of 90 meters is 20dB, it means that the signal strength has dropped by a
Read article →Technical articleBandwidth, Frequency and Data Rate
It is necessary to understand a number of basic terms before discussing the limitations of network cabling and data communications, which we plan to discuss in details in our blog posts in future. Engineers, vendors and network managers often use many communications and high-tech terms when they
