What Are Patch Cords and How They Make Distribution of Transmission Signals Possible

Patch cords are actually cables and like any other cables; they are used to connect electronic devices. Using patch cords, you are able to use one system device with another. Two or more electrical equipment can be operated simultaneously when connected by patch cords. Hi-tech audio and visual systems and computer networks use this type of connectivity.

Take a look behind a home theatre system or a network of several computers and you will see a web of cords. Did you notice those short colored cables? Those are patch cords that serve as the path for signals to travel from one device to another.

Patch cords are color coded, mostly in yellow, green, white and brown. Did you see those colored terminal ports too? The outer bearing of the terminal ports are likewise colored accordingly, also in yellow, green, white and brown. The patch cords are plugged into several ports at the back of the device. The color makes it easy to distinguish which cord goes into which port.

The cord is no more than two meters in length and has a plug on both ends. One end is to be plugged into the terminal of the primary device and the other into the port of usually an accessory device. Since there could be more than two cords attached from one device to another, expect a mesh of cords. Some people find the entangled cords a bit messy, which prompted some manufacturers to come up with rubber clips to hold them. This has also paved the way for the introduction of patch cords that consist of several cords encapsulated in a single cable. Having a single cable with several cords reduces the clutter.

The RJ-45 is a well known patch cord in the world of computer networking. Networking systems use Ethernet patch cords, which are coaxial in nature. When you say coaxial, it means that the wirings inside the cable are primarily built for use in transmission lines. It transmits radio frequency signals and cable television signals through transmitters, receivers like antennas, and network connections in computers. When used in computer network, the Ethernet is the connecting cord between the hub or the main switch of the network and the computers involved.

Electronic signals are inversely proportional to distance. This means the longer the distance of the cord from the main switch to the receiving device, the weaker is the signal being transmitted. It should be that as much as possible the secondary device, being the recipient of the signal, is close to the mother source of the signal. That is why shorter patch cords are highly recommended. In the event where longer patch cords need to be utilized, use quality cables being that longer distance means more probability of interference while signal is en route.

Poorly made patch cords reduce the quality of the signal being transmitted and inevitably affects the performance of the device. A quality cable should be able to live up to what it is made for in the first place.

What Does CAT 5 Cables Do And Other Basic Facts About Networking Using Ethernet Cable

CAT 5 cable is short for category 5 cable and it is the layman’s term for Ethernet cable. Some people find it hard to understand what CAT 5 cable is and for what purpose it is used for. If you have a computer device at home, chances are you have seen what it looks like. It is that blue cable that runs between the terminal port of your computer or laptop and the modem.

They basically transmit internet signals from the modem to your computer. Try taking the blue cable off your computer and you will not have an internet connection. You will notice that when you look at the modem, the yellow light above the description “Ethernet” is dead. That is supposed to light up when connection between the modem and the laptop is established and that is only possible if you connect a CAT 5 cable properly.

This type of cable comes in many colors with blue being the most commonly known color. They can also be made to order size and colors depending on your needs.  At a closer inspection, you will notice on both ends of the CAT 5 that there are twisted pairs of wires individually wrapped in a plastic cable of different colors. There are blue, orange, yellow, green, white smaller cables inside the plastic sheath on both ends of the cable.

The individually wrapped smaller cables inside insulates the signal from outside interference making sure information is transmitted from one terminal to another completely and in a timely manner. They eliminate latency when there is a heavy flow of information. Besides giving you a smooth signal, it also protects important and confidential information wired through the internet such as bank transfers, payments and other activities online that involves private details.

The CAT3 was replaced by the more enhanced CAT 5 that carries a speed of 100 mbps or more. CAT3 only supports data at a speed of 10 megabits per second so that is quite a difference. The CAT 5 can be laid down in up to 100 meters or 300 feet distance at standard. The CAT5e is an advanced version of the CAT 5 cable because it supports data at 1,000 mbps. When used with 100 Base-T networks, it can cover 1,150 feet or 350 meter distance. The CAT 5 cable is best installed with a CAT 5 cable reel. The cable reel makes it easy for you to install the cable even without the help of a computer technician. Contracting the service of an expert to lay out the cables may even cost more than the actual cost of the cable reel itself. When it is a simple networking job mainly for personal use, you can set out the cable yourself with the aid of a cable reel. CAT 5 cable with RJ-45 jacks can be found together in the market which makes it much easier and convenient because you will have little to work on.

New HDMI 1.4 Specs On the Horizon

According to a recent release from the HDMI Consortium, the group is preparing to add new specifications to its requirements for the HDMI (high-definition multimedia interface) 1.4 cable, including support for 3D gaming and movie watching. This innovation could potentially change the way that people enjoy entertainment within their own home theater systems.

The release, which went out December 23, 2009, indicated that the HDMI Consortium, which outlines specifications for HDMI technologies and is made up of Hitachi, Panasonic Corporation, Royal Philips Electronics, Silicon Image, Sony Corporation, Thomson and Toshiba Corporation, will meet in late January 2010 to add the 3D format, currently called “Top/Bottom”, to the HDMI 1.4 specifications. Once the group decides on the format, it would be mandatory for consumer electronics to offer ports and support for 3D viewing.

Devices such as set-top boxes and HDTVs would be affected by the change, which comes as no surprise as several TV makers have forecasted showing off 3D technologies within the coming year at various electronic shows and exhibits. In fact, LG has said that it expects to ship hundreds of thousands of 3D-capable TVs in 2010 and the Blu-ray Disc Association has finalized 3D disc specifications in time for production.

As the governing body for all standards in HDMI technologies, the HDMI Consortium is responsible for all changes in the make and design of HDMI cables as well as HDMI technology advancements and standardization. Basically, they outline how HDMI cables and compatible devices are supposed to be made and used.

Many HDMI supported devices and cables are regulated and made to 1.3 specifications and most home theater owners agree – it’s time for an upgrade. Right now, the handling of legacy systems is still under discussion, however, it looks like some will be able to support the format while others may not. With the advancements in technologies coming up in 2010, it’s almost essential for home theater equipment to follow with the trend.
