Unshielded twisted-pair (UTP) is a type of twisted cable that has two or four pairs of wires. This type of cable relies solely on the cancellation effect produced by the twisted wire pairs that limits signal degradation caused by electromagnetic interface (EMI) and radio frequency interference (RFI).
What are two characteristics of fiber optic cable? What are two characteristics of fiber-optic cable? (Choose two.)
- It is not affected by EMI or RFI.
- Each pair of cables is wrapped in metallic foil.
- It combines the technique of cancellation, shielding, and twisting to protect data.
- It typically contains 4 pairs of fiber-optic wires.
Similarly, Why are twisted pair cable twisted? Twisted pairs are made up of two insulated copper wires that are twisted together. The twisting is done to help cancel exterior electromagnetic interference. Crosstalk interference can come from other pairs within a cable. Each type of twisted pair cable has bandwidth and data rate specifications.
How many pairs of cable are in a twisted pair cable?
Four pairs of ‘wires’ are there in ‘twisted pair cable’ (Ethernet). Ethernet Port is used to connect ‘Ethernet cable’ to a ‘computer’ or a laptop.
How many pairs are in a twisted pair cable?
Unshielded twisted pair (UTP) cables are found in many Ethernet networks and telephone systems. For indoor telephone applications, UTP is often grouped into sets of 25 pairs according to a standard 25-pair color code originally developed by AT&T Corporation.
What is the purpose of cladding in fiber-optic cables?
Cladding: The function of the cladding is to provide a lower refractive index at the core interface in order to cause reflection within the core so that light waves are transmitted through the fiber.
What are characteristic features of satellite Internet connections? 25 Cards in this Set
| Which of the following answers refers to an international standard for high-speed data communications over fiber-optic media? | SONET |
|---|---|
| What are the characteristic features of satellite Internet connections? | Signal latency Interference (weather dependent) Low connection speed |
What makes fiber preferable to copper cabling for interconnecting buildings? Answers Explanation & Hints:
Optical fiber cable transmits data over longer distances and at higher bandwidths than any other networking media. Unlike copper wires, fiber-optic cable can transmit signals with less attenuation and is completely immune to EMI and RFI.
How many types of UTP cables are there?
There are five types of UTP cables — identified with the prefix CAT, as in category — each supporting a different amount of bandwidth. Alternatives to UTP cable include coaxial cable and fiber optic cable.
Are there different types of coax cables? There are three types of coaxial cables: RG59, RG6, and RG11. While RG6 is the most widely used coaxial cable, RG11 and the lower end RG59 are also useful for specific connections. Here are the basics on each type: RG59 is the low end of coaxial cable options.
What is the difference between coaxial cable and twisted pair?
The Major Differences Between Coaxial Cable and Twisted Pair
Coaxial cables support greater cable lengths. Twisted pair cables are thinner and less expensive. Coaxial cables are better shielded from crosstalk. Twisted pair cables provide high transmission rates.
What is the type of modulation used by twisted pair cable? « Line coding is the type of modulation used by twisted pair cable computer networks » Explanation: Line coding is a process carried out by a transmitter that transform data, in the form of binary digits, into a baseband digital signal that will describe the data on a transmission line.
Which of the following connector types is used for coax cable?
The most common type of connector used with coaxial cables is the Bayone-Neill-Concelman (BNC) connector (See fig. 4).
What are the different types of fibre optic cables?
There are three types of fiber optic cable commonly used: single mode, multimode and plastic optical fiber (POF).
What are the 2 types of fiber optic cable and what are their functions and how they it works? There are two primary types of fibre – multimode and singlemode. Multimode fibre can carry multiple light rays (modes) at the same time by having varying optical properties at the core; essentially light travelling the shortest path (down the middle) travels the slowest.
Which is denser core or cladding?
In an optical fibre, the core is always less dense than the cladding.
Which are types of Internet connections choose three answers?
The most common types of internet connections include:
- DSL (digital subscriber line)
- cable broadband.
- fibre optic broadband.
- wireless or Wi-Fi broadband.
- satellite and mobile broadband.
- dedicated leased line.
Which of the following is the most common type of DSL Internet access? There are many forms of DSL. The most common forms of DSL are asymmetric DSL (ADSL) and symmetric DSL (SDSL).
Which one is a broadband wireless technology?
Emerging broadband wireless technologies (Fig. 6.1) include Worldwide Interoperability for Microwave Access (WiMAX/IEEE 802.16), Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), High Speed Packet Access (HSPA), HSPA+, Cloud Radio Access Networks (C-RAN), etc.
What two factors could interfere with the communication carried over UTP cables? In addition to the cable length, what two factors could interfere with the communication carried over UTP cables? (Choose two.)
- crosstalk.
- bandwidth.
- size of the network.
- signal modulation technique.
- electromagnetic interference. Answers Explanation & Hints: Copper media is widely used in network communications.
What are three characteristics of UTP cabling?
What are three characteristics of UTP cabling? (Choose three.)
- susceptible to EMI and RFI.
- commonly used for Internet connectivity by a cable TV provider.
- easiest type of networking cable to install.
- commonly used between buildings.
- uses light to transmit data.
- most commonly used networking cable.
What is cable type? The following sections discuss the types of cables used in networks and other related topics. Unshielded Twisted Pair (UTP) Cable. Shielded Twisted Pair (STP) Cable. Coaxial Cable. Fiber Optic Cable.
What are the two distinct types of UTP communication media?
There are two types of twisted pair cables used for most in-building situations today – Category 3 UTP (CAT 3) and Category 5 UTP (CAT 5).
What is the difference between Cat3 and Cat5 cable? Found in both the office and the home, the two cables have different physical characteristics. A Cat5 cable generally features a thicker cable diameter and an RJ45 connector. A Cat3 cable is typically thinner and features a smaller RJ11 or RJ24 connector.
