Berk-Tek was featured in the March/April edition of BICSI's publication, The Journal of Information Technology Systems.
Many of us are currently aware that expanding bandwidths, added power and connecting unrelated devices via Internet protocol (IP) are pushing twisted pair cable to its operational and electrical signal-carrying limits.
Berk-Tek's article presents three separate real world installation scenarios, recreated in a lab, studying the effects of interference and noise on copper cable. These studies provide network designers with multiple considerations that can easily be overlooked during cable selection.
Interference in the form of noise can come from a multitude of unknown sources- from electrical surges to elevators, adjacent cables to simultaneously running technology, higher susceptibility to external noise is critical when data rates are increased, requiring higher signaling speeds and more complex encoding.
The tests Berk-Tek designed go so far as to use copper cabling in complex scenarios when the cable must simultaneously transmit data, video, and power, testing the durability and performance of six cable varieties.
With the addition of other applications now attaching to the IP network, new 'what if' scenarios and environments that may affect the installed copper cabling system begin to surface. In the near future, more and more unrelated devices and applications will continue to attach to the data network to take advantage of the benefits of structured cabling- easy migration, uninterruptible power supply back up and 24/7 support to name a few.
The article delves deeper into our networks' needs today, including
- Accomodating devices
- Expanding bandwidth needs
- Pushing the limits
