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...

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 ...

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 yo...

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 so...

Digital Signal Processing is the process of transmission and production of data that takes place without any interference. This process asks for an Ethernet Cable. Most of the wired networks of today including routers, PCs and switches use   Ethernet cables   for the smooth transmission of data. These Ethernet Cables are of two types – Shielded and Unshielded. They are also known as STP (Shielded Twisted Pair) and UTP (Unshielded Twisted Pair). The question that arises next is – which one out of the two you should buy? To find this out, make sure you know about the environment you need Ethernet cables for. One of the major reasons behind networks slowing down is – voltage interference. Hence, you must make sure that the electrical line intersects with low voltage communication cable at 90 degrees. Given below are some other factors you should consider before buying shielded or unshielded Ethernet cables. Alien CrossTalk The antenna of Ethernet cables are like the cro...

When you undertake installation of your devices with   power cords , you must have observed in the specification sheet that one part of the cord is approved and another isn’t. This might lead you to wonder as to why is it so? Well, it can be a bit tricky to understand international approvals of cords. Let’s obtain a detailed understanding behind the process of approvals and regulations. Approvals in parts Every power cord that you come across is approved in its parts and not as a whole. Its connector, wire and plug are approved differently. Although the IEC standard connectors are used all over the world, the standards of their approval change from one country to another. This authorization depends on the agency they are being approved by. For eg, in China and Argentina, the whole cord set is approved instead of its parts. IEC Regulations The International Electrotechnical Commission (IEC) based in Geneva, is an association that establishes international standards for the...

People who carry out installation procedures often come across plugs that are labeled ‘NEMA’-National Electrical Manufacturers Association. Over the years, this label has earned the reputation for being a safe and standardized product. There is an array of plugs offered by NEMA and there often is a confusion regarding which one is the best. Here’s a brief overview of these   power cords   and their types. Standard North American Power Cords The standard North American Power Cords come with two, three, four or five prongs. Out of these   NEMA power cords , plugs with two or three prongs are most popular. These plugs fit with every standard wall outlet of Canada and United States. Most of these configurations include 5-15, 5-20, 6-15 and 6-20. Hospital Grade Power Cords Power cords that are utilized in hospital must meet certain standards and requirements set by Underwriters Laboratories (UL). UL conducts rigorous testing on these cords to approve its durabi...

HDMI , also known as High Definition Multimedia Interface is an advanced technology that is used for transmitting digital data between two digital devices. This technology was developed by leading electronics manufacturers like Philips, Toshiba, Hitachi, Sony etc. Ever since it was introduced, it has become quite popular. Its latest version, 2.0, was introduced in September 2013. If you are new to   HDMI Cables   or   HDMi adapters , and want to know more about it, take a look at some frequently asked question and their answers. These will give you more insights about HDMI cables and their working. What is the purpose of HDMI technology? HDMI technology is mostly utilized to transmit multichannel audio and high definition video data between two digital devices. This process of transmission takes place through a single cable. You will be able to find HDMI technology in all the latest electronic equipment including AV receivers, personal computers, set top boxes...
