Keystone Jack is one of the most commonly used elements in networking. They are used for networking installations when a computer is connected to a network port. Keystone Jacks have a standardized design. They are created in such a way that they can be fixed into patch panels, keystone plates and keystone boxes.
For establishing a connection, the keystone jack is pushed into a port and can position itself easily. If you want to get it out, you can do it by pulling the tab. One of the biggest drawbacks of keystone jack design is that its rear profile is bigger than the front. Due to this, one cannot put a keystone jack in a single location. Also you cannot put in too many number of keystone jacks in a single location. Given below are some commonly asked questions about Keystone Jacks along with their answers. Why Should I use Keystone Jacks? Keystone Jacks are flexible and you can install them into a wall plate quite easily. You can also install different keystone jacks into one keystone plate having multiple ports. As these wall plates are available in different finishes and colours like golden and black, you can customize them according to the interiors of your home or office. There is an array of options available with the type of Keystone Jacks. And needless to say, they provide a clean, neat and a professional look. If you want a good connection, the wires must be crimped on the keystone jack in the right manner. What kind of Keystone Jack Should You Use? The network cable guys usually use standardized Keystone Jacks. However, if you have lack of space for installing these, you can consider going for high density Keystone Jacks. The smaller the footprint, the more connections you can set up using them. What is a high density keystone jack? The snap-in dimension of a high density keystone jack is similar to that of a standard keystone jack. The front profile of a high density keystone jack is also like standard keystone jack. Both standard and high density jacks are rectangular in shape and have flexible tabs. They are also used for the same purpose. So what’s The Difference between High Density and Standard Keystone Jack? The rear physical profile is the only feature that is different in both. The High Density Keystone Jack is much slimmer as compared to the standard one and it enables one to install more jacks. They also have a narrow rear profile for you to be able to accommodate more Keystone Jacks. These are some of the commonly asked questions about Keystone Jacks. Other aspects of using them totally depend on your utility and purposes. You can research about these and choose one from our collection of Keystone Jacks that suits your requirements the best.

When it comes to Ethernet Cables, the most commonly asked question is, “What is the difference between CAT6 ethernet cables and CAT6A ethernet cables?” It is not just the letter ‘a’ that sets them apart. At first, only CAT6 was used for networking purposes. As 6A came in, people started upgrading and switching to CAT 6A. So what are the basic differences between these two and how can you tell the difference between them? Read further to know. Telling them apart A very apparent way to identify the difference between them is to read their names on the cable jacket itself. They both have their names imprinted on the cable jacket when you buy them. One more difference between them is that CAT6A cables are thicker as compared to Cat 6 cables. Both are available in several colours. Shielded vs. Unshielded One more small difference between these two is their insulation. Ethernet cable is usually surrounded by thin jackets to protect the inner twisted pair of wires. These jackets are a reason why we identify the Ethernet cables as Shielded Twisted Pair (STP). The cables without these jackets are known as unshielded twisted pair (UTP) cables. Although you can buy shielded Cat6 cables, there are more chances that you will find unshielded ones. On the other hand, all of Cat6A cables are shielded. Shielded cable stops the interference caused due to the heavy electromagnetic interference (EMI). Shielded cables are mostly needed for industrial surroundings and unshielded ones can be used at home or offices. Performance Even though Cat6A doesn’t push up the speed of data transmission, it has the capacity to transmit upto 10 Gbps. It doubles up the frequency of data transmission from 250 MHZ to 500 MHZ. This also enables remote data transmission. Cat6A can make this possible if its twisted wire pairs are twisted around a plastic support. Wiring CAT6A cable is manufactured by using 4 to 10 pairs of tightly twisted copper wires. It is possible to transmit data by using these wires. However, cable length and interference might become a hindrance. If the pair is very tightly woven, it can resolve such problems. Cat6 cable is manufactured using precise standards unlike its previous versions. The intent behind manufacturing them was to provide the speed of 10 gigabytes per second. Hence, the difference between CAT6 and CAT6A cable is wiring. Costs As compared to CAT5E cables, Cat6 and 6A cables are more expensive. There is a 20 to 35% cost difference between Cat6 and 6A cables. So now you know the difference between the two. It is better to install CAT6A cable when there are more chances of alien crosstalk or interferences as they are shielded. You can decide which Ethernet cable out of the two would suit you depending on the surroundings where you intend to use it. CAT 5E Cable is the successor of CAT5 cable and predecessor of CAT6 cable. CAT5E ethernet cables are mostly used for multi-line phone systems and networks. They are also used for plugging a computer or laptop into a modem for carrying internet connections. They have a maximum frequency of 100 MHz and are capable of transmitting up to 10/100/1000Mbps data. You might be aware of the uses of these networking cables. However, having some more details about these cables will help you understand its utility better. Take a look at some other aspects that you probably didn’t know about.
CAT 5E Cables are commonly unshielded 5E cables are commonly unshielded but are also available with shielding. When it comes to noise rejection, they depend on the balanced line twisted pair design and differential signaling. Length of cable segment The length of the cable can change but the maximum length that it can have is 100 meters per TIA/EIA 568-5-A. Just in case you go for a length that is more than the one mentioned here, you might have to use a switch to make sure there are no issues with the connection. Crosstalk Crosstalk is a major aspect that sets Cat5 and CAT5E cables apart. The latest cables are better in quality as new specifications have been added to them. However, even CAT5 cables could pass for ‘e’ standard if they were certified accordingly. Insulation, Conductors and Twist Length CAT5E Ethernet cables are insulated using PVC or LSOH material. These conductors have a standard between 22 American Wire Gauge (AWG) and 24 AWG. They cannot be thinner than these standards. Available in multiple colours As CAT5E cables can be obtained in different colours, it becomes easy to recognize the utility of each connector. This stands true especially for companies with huge IT infrastructures as they do not have much time for troubleshooting. So the network person that installs these cables can arrange them according to the functionality. For eg. Blue cables for making connections and red cables for access points. If you want to network different electronic devices, CAT5E Ethernet cables would be the right choice. They are also unparalleled when it comes to strength and durability. But before buying these, make sure you research about all kinds of ethernet cables. You must also know your purpose behind using these cables well so that there are no issues at a later stage. Yet another day at a local hospital in this rural setting in and facing regular electricity cuts like usual, did not bother me much until a serious emergency case arrived in the hospital. It was a case of cardiac arrest and we required all medical equipment's fully functional then and there!
Suddenly when we were not able to connect one of the ventilator wires, a newly joined ward boy suggested of using just another Computer Power Cords to replace and make the equipment functional for the time being. I found the suggestion suitable bit, luckily the more experienced nurse stopped him doing the same and explained that it is very important to understand hospital grade power cords being different from the ones we use otherwise; or else, it will not just affect the equipment but ultimately a patient’s life which is more precious than anything else. A power cord, mains cable or line cord is a cable, which temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage. The terms power cable, mains lead, flex or kettle lead are also used. A lamp cord (also known as a zip cord) is a light-weight, un-grounded, single-insulated two-wire cord used for small loads such as a table or floor lamp. This is something I gathered from various sources when i tried to understand to discuss it further, as to what makes hospital grade power cords different from other power cords. Power cords used in hospital environments are subject to special requirements rigorous tests which check durability and conductivity to ensure that the product operates at peak levels. Once a product line is approved, it is stamped with mark of safety. That is why Medical Power Cords are often referred to as Hospital Grade Power Cords. Hospital Grade Power Cords are divided, basically into three categories: Cords with One End feature exposed wire on the opposite end making them ideal for hard-wiring into appliances. Cords with Two Ends, which are used when the application you are powering has a built-in inlet for the connection. Finally, Multi Leg Cords feature a splitter that supports two or more receptacles. Though, various countries have standards for the overall medical equipment, a few countries have standards regarding specific medical-related components like plugs and cords. It should also be understood that, for the countries which have hospital-grade or medical application standards on components, it is very important to know what the requirements are so as to comply with that country or region’s rules. As gathered from various sources, countries/regions that have hospital-grade or medical application standards on specific components include: Australia/New Zealand, Denmark, Japan, and North America. Power cords and cord-sets as well as plugs and sockets are subject to special rules. Aside from these regions, there is no differentiation for plugs, sockets, and cords used in a medical setting versus a non-medical setting. |
