For creating a network in a network, we must connect a portable device with the central processing unit (CPU). The USB cables, optical fibers and other Networking cables facilitate this. However, these network cables are worthless if a port does not mount on the unit. A cable can not be connected to the central unit or the port unit with the device!
So, what enable our portable devices like keyboard, pointer, printer, digital camera connect with the CPU using Ethernet cables , USB Cables or optical fibers?
The answer is a Keystone Jack!
What is a Keystone Jack?
A Keystone Jack is the magic port, which aids this functionality. Every connecting device has a female unit installed on them. Networking cables have the attachment of keyboards, which have the name “keystone plugs.” They connect where we want to connect. Hence, Keystone Jacks are one of the most important units in networking. They have a fix to keystone plates, keystone boxes, and patch panels.
Nature of Keystone Jacks
They have a standard design, they are flexible, and they are easily mountable, even on the wall! Multiple keystone jacks on a single plate with multiple ports. They are available in multiple variations.
Keystone jacks have an extensive use in data communications.
The manufacturing of these tools is in a standard size for their usability in patch panels, surface mount boxes and keystone wall plates. This means we get a universal fit across all brands.
There are some variations, however, as high-density keystone jacks have designs to maximize space when working in a congested area. These jacks permit fitting of more individual jacks into a single patch panel and have a design for use in high-density patch panels.
Cat5e, Cat6, Cat6a Dilemma
Cat5e and Cat6 cables plug into the same keystone Jack of your Ethernet jacks, routers, and switches. However, have a distinct use, design, and application. Both these cables come with twisted pair cables consisting of copper wires.
The Cat5e Keystone Jack supports speed limit up to 1000MBPS and the Cat6 has a speed limit up to 10GBPS over 120-150 feet. The speed of cat6e has a 10GBPS (Gigabit) limit to 164 feet and thereafter its speed is the same as that of Cat5e.
The cost of the cables varies. The standard Cat5e costs generally around $ 0.20 per foot. In addition, the standard Cat6 costs around 20% higher than the Cat5e.
The Cat5e frequency range is up to 100MHz and in contrast, that of Cat6 is up to 250MHz. Hence, it has a higher sound to noise ratio and is more rigid as compared to Cat5e. The tighter twist of the Cat6 allows it to conduct two-way communication and it is faster than that of Cat5e.
You can not identify the cables on the cable. Even though you can identify Cat6 without the print as it is thicker than Cat5e, it consists of a thicker copper wire.
Keystone jacks Cat5e and Cat6 both are sound options. When the servers have a place on the clouds, Cat5e is more economical as the internet connectivity will be efficient enough. Cat6 certainly does not work with better performance and it is much efficient if you have a better investment option above 120-150 feet.
