In its simplest form, twisted-pair cable consists of two copper strands woven into a braid and covered with insulation.
Two types of twisted pair cable are generally recognized:
A cable is often made of several twisted pairs grouped together inside a protective jacket. The twisting eliminates noise (electrical interference) due to adjacent pairs or other sources (motors, relays, transformers).
Twisted pair is therefore suitable for a local network with few nodes, a limited budget and simple connectivity. However, over long distances at high data rates it does not guarantee data integrity (i.e. loss-less data transmission).
UTP cable complies with the 10BaseT specification. This is the most commonly used twisted pair type and the most widely used on local networks. Here are some of its characteristics:
What is the general difference between category 5e and category 6?
The general difference between category 5e and category 6 is in the transmission performance, and extension of the available bandwidth from 100 MHz for category 5e to 200 MHz for category 6. This includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). These improvements provide a higher signal-to-noise ratio, allowing higher reliability for current applications and higher data rates for future applications.
Will category 6 supersede category 5e?
Yes, analyst predictions and independent polls indicate that 80 to 90 percent of all new installations will be cabled with category 6. The fact that category 6 link and channel requirements are backward compatible to category 5e makes it very easy for customers to choose category 6 and supersede category 5e in their networks. Applications that worked over category 5e will work over category 6.
Most telephone installations use UTP cable. Many buildings are pre-wired for this type of installation (often in sufficient number to satisfy future requirements). If the pre-installed twisted pair is of good quality, it can be used to transfer data in a computer network. Attention must be paid, however, to the number of twists and other electrical characteristics required for quality data transmission.
UTP major problem is that it is particularly susceptible to interference (signals from one line mixing with those of another line). The only solution to this is shielding.
STP (Shielded Twisted Pair) cable uses a copper jacket that is of better quality and more protective that the jacket used for UTP cable. It contains a protective envelope between the pairs and around the pairs. In an STP cable, the copper wires of one pair are themselves twisted, which provides STP cable with excellent shielding, (in other words, better protection against interference). It also allows faster transmission over a longer distance.
How much Bandwidth to I need between my source and display ?
Several different Video / Audio streams are listed below and this guide is a maximum required for transmitting these signals. Please use this guide to determine which type of HDMI cables will suffice and which type of ethernet / network cabling you need to use when transmitting HDMI signals over ethernet / UTP / STP. This features as a guide only and if you are unsure regarding which type of cabling to use rather go for Category 2 HDMI cables for HDMI to HDMI connections and CAT6 / CAT7 cables for HDMI over network configurations. If the cable length in general is > 25 meter and there might be electrical interference nearby the cable go with STP / Shielded Twisted Pair cabling from the categories below. Specific brands of CAT5e / CAT6 and CAT7 quality also differs so rather go with the brand we sell or purchase a brand that conforms to the correct specifications.Type of Video | Resolution | Horizontal Pixels | Vertical Pixels | Compression Used | Frames per second | Signal Type | Color bit Level | HDMI Bandwidth Required | Type of HDMI v1.3 Cable Required | Type of Ethernet Cabling for HDMI over Ethernet |
