How many twisted pairs of wires are typically used in a leased line between two routers?
Ans:- Two pair of twisted pair Cable
What are twisted pair cable wires made of?
if by "twisted pair cable" you mean a cat5 cable which is commonly used as an ethernet cable. then it´s made of copper.
Where is shielded twisted pair used?
A shielded twisted pair or STP is a copper telephone cable that secures signal-carrying wires inside a conducting shield. It main purpose is to reduce the possibility of electromagnetic intrusion.
Twisted pair cables?
A type of cable that consists of two independently insulated wires twisted around one another. The use of two wires twisted together helps to reduce crosstalk and electromagnetic induction. While twisted-pair cable is used by older telephone networks and is the least expensive type of local-area network (LAN) cable, most networks contain some twisted-pair cabling at some point along the network. Other types of cables used for LANs include coaxial cables and fiber opticcables.
Why twisted pair wire is called twisted pair?
Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed in a shield that functions as a ground. This is known as shielded twisted pair (STP). Ordinary wire to the home is unshielded twisted pair (UTP).Twisted pair is now frequently installed with two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for modem use) when you need it.Twisted pair comes with each pair uniquely color coded when it is packaged in multiple pairs. Different uses such as analog, digital, and Ethernetrequire different pair multiples.Although twisted pair is often associated with home use, a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive thancoaxial cable.The wire you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of hole arrangements or pinouts, depending on the kinds of wire the installation expects will be plugged in (for example, digital, analog, or LAN) . (That's why you may sometimes find when you carry your notebook computer to another location that the wall jack connections won't match your plug.)
Can twisted pair cable used for LAN connections?
twisted pair cable can used as LAN connections....for example CAT5 and CAT6 both twisted pairs.
Why is a twisted pair cable is not used for LAN connectivity?
Twisted pair is less sensitive to noise and crosstalk as the two wires in the pair are so close together that they generally both pick up the disturbance identically, then the receiving circuit cancels this common mode disturbance out. Twisted pair is also much less expensive than fully shielded cables like coax.
Which type of transmission medium consists of a number of individually insulated copper wires?
The type of transmission medium that consists of a number of individually insulated copper wires is called twisted pair cable. This type of cable is commonly used in Ethernet networks for data transmission due to its affordability and ability to reduce electromagnetic interference.
What cable generally contains eight wires with either four or eight wires being used to transmit data?
Any category twisted pair cable uses 8 wires for transmitting and receiving data. However, only 4 of the 8 wires are actually used for data transmission.
Why two wires are used in twisted pair cable?
You may need a "return" for the signal. If you do not the other wire is twisted in various configurations along the length to reduce crosstalk and signal leakage. It is easier to balance capacitive loads,
When the signal from one pair of wires interferes with the signal on another pair of wires its called?
When the signal from one pair of wires interferes with the signal on another pair of wires, it is called "crosstalk." This phenomenon occurs when the electromagnetic fields produced by the signals in one wire pair induce unwanted signals in another wire pair, leading to degradation of the original signal quality. Crosstalk can be particularly problematic in telecommunications and data transmission systems. Measures such as shielding and twisted pair construction are often used to minimize crosstalk.
What Cable consists of color-coded pairs of insulated copper wires of each with a diameter of 0.4 to 0.8 mm?
This is a description of twisted pair cable, which is commonly used in network and telephone wiring. The color-coding helps to identify the pairs and reduce crosstalk. The copper wires are insulated to prevent short-circuits and maintain signal integrity.
