Brexons Installations are experienced installers of structured cabling solutions.(a standardized cabling system designed to integrate voice, data and video signals.)The entire cabling infrastructure is presented on a patch panel. To change the connectivity is as simple as plugging the appropriate patch lead or adapter into the relevant RJ45 port. There are several cabling systems available, however the choice depends on both the current network requirements and the argument for future proofing. Whilst IT departments expect the cabling infrastructure to last between 15 and 20 years, desktop pc’s, network switches and servers will be replaced and upgraded several times during that period. Category 5e (ANSI / TIA / EIA 568-B) is a specification to support performance characteristics up to 100 MHZ and data transfer rates of up to 1 Gigabit per second, a 4 pair high performance cable that consists of twisted 24 gauge copper conductors. At present most end users find 100Mbit/s fast Ethernet connections more than sufficient for most of the applications they run. As such 1Gbit/s links are never used to anything approaching their full capacity, however that may change soon especially for those working with sophisticated multimedia applications accessing streamed video and graphic elements.


Category 6 is a specification to support performance characteristics over a gigabit per second and a bandwidth of 250 MHZ. Each pair is isolated from the other pairs by an internal separator designed to significantly improves the insertion loss, return loss and cross talk providing a better signal to noise ratio. Because of the improved transmission performance and superior immunity from external noise allows for higher reliability in current applications and higher data rates for future applications The general difference between category 5e and category 6 is in the transmission performance, and speed. Category 5e can support up to 1Gb/s and Category 6 can support 1Gb/s - 10 Gb/s. While Cat 6 may support 10 Gig in shorter links of less than 55 meters, Cat 6 ANEXT performance will likely not enable it support 10 Gig to the full 100-meter channel.


Cat6a or Augmented Catergory 6 is the latest standard defined for twisted pair cable for frequenciesw up to 500 Mhz, currently supporting 10Gbit/s applications (10 Gbase T ethernet). 10 times improvement in bandwidth and Improved specifications, particularly in the area of Alien Cross-talk (AXT) as compared to Cat6 UTP which exhibited high alien noise in high frequencies. The 10Gbase-T standard was originally intended for data centres and short transmission distances between servers however we have installed numerous Cat6A solutions for customers wanting to future proof the desktop end user. For and against for installing Cat6A Ethernet technologies are continuously improving from fast Ethernet, gigabit Ethernet and 10 gigabit Ethernet however Cat5e and Cat6 are capable of 1 gigabyte applications which is more than adequate for the foreseeable future. Cat6a cabling systems are very new and expensive. The price per port for a 10Gbase-T switch is very expensive at the moment although this will come down in the future, as more and more solutions are available. Cat6A cable is much thicker than its predecessors and as such requires extra sized containment including larger trunking basket and tray. Installing Cat6A now is one of future proofing depending upon the lifetime expectancy of the network cabling infrastructure and playing safe by having the fastest cabling system available. Cat6A is the only choice for Data Centres, server room and network backbone links.
