[Q] What’s the difference between CAT 5 cable and CAT5e cable?
[A] CAT 5 cable and CAT 5e cable have several differences, the most important are as follows:
[Q] What is the difference between CAT 6 and CAT 5e cable?
[A] Currently there is a great deal of confusion among Ethernet cable buyers concerning whether to purchase Cat5e, or to use Cat6. Most of this confusion comes from a misunderstanding by the buyer that buying Cat6 cable will give them an “all gigabit” network. This is not the case. Unless every single component in the network is gigabit rated, then you will never have a gigabit network, because your network will always run at the speed of your slowest device. Cat5e cable of good quality can run near or at gigabit speeds, it just cannot be “certified” for this use. By comparison, Cat6 is designed especially for gigabit use, and is certified to operate at said speed. It becomes a matter of whether or not you want to pay all that extra money, for little or no noticeable improvement in the performance of your network. In most cases, it makes more sense to go with Cat5e. It is for this reason that most of your new installations in the private sector are going with Cat5e. It is more economical, performs well, and is readily available in many colours. Many IT professionals when asked about why they specified Cat6 for a specific job, often responded stated that they “wanted the best they could get.” This is the line of thought behind many purchases of cable.
Multimode fibre cabling is a common choice to achieve 10-Gbit/sec speeds over distances required by LAN enterprise and data center applications. But several grades of high-bandwidth laser-optimized fibre are available for use in high-speed network installations, and each with a different reach and data-rate capability. It can be challenging to select the most suitable fibre grade for a given system. It may even be necessary to mix fibre already deployed across the network with newer, higher grades.
•50/125-µm (OM2) fibre, used to achieve 1-Gbit/sec data rates and higher;
•50/125-µm (OM2+, OM3, and OM3+) fibre, used to achieve 10-Gbit/sec data rates and higher. OM2+ and OM3+ fibre grades offer nearly double the bandwidth of their parent fibres (“+” represents extended-reach OM2 and OM3 fibre
