Backbone cabling consists of the backbone cables, intermediate and main cross-connects, mechanical terminations, and patch cords or jumpers used for backbone-to-backbone cross-connection.
Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Backbone cabling consists of the transmission media, main and intermediate cross-connects and terminations at these locations.
One may also ask, which type of cable is used for creating backbone channel? The 62.5-micron fiber cable used for the backbone is immune to electrical interference.
Also to know, what does backbone cabling consist of quizlet?
Backbone cabling consists of: the backbone cables, intermediate cross-connect (IC [building distributor(BD)]), main cross-connect (MC [campus distributor (CD)]), mechanical terminations, and patch cords or jumpers used for backbone-to-backbone cross-connection.
What is structured cabling Why is it important?
Structured cabling standards help organizations install wiring in a way that prevents these messy tangles by keeping the whole wiring infrastructure organized. Structured cabling solutions enable just that, making updates easy to implement with minimal risk to the infrastructure.
Who owns the backbone of the Internet?
Because of the enormous overlap between long-distance telephone networks and backbone networks, the largest long-distance voice carriers such as AT&T Inc., MCI (acquired in 2006 by Verizon), Sprint, and CenturyLink also own some of the largest Internet backbone networks.
What are cabling standards?
The TIA/EIA structured cabling standards define how to design, build, and manage a cabling system that is structured, meaning that the system is designed in blocks that have very specific performance characteristics. The blocks are integrated in a hierarchical manner to create a unified communication system.
What is cable infrastructure?
A structured cabling system is a complete system of cabling and associated hardware, which provides a comprehensive telecommunications infrastructure. This infrastructure serves a wide range of uses, such as to provide telephone service or transmit data through a computer network.
What do you mean by Ethernet?
Ethernet is a way of connecting computers together in a local area network or LAN. It has been the most widely used method of linking computers together in LANs since the 1990s. The basic idea of its design is that multiple computers have access to it and can send data at any time.
What is a network cable used for?
Network cables are used to connect and transfer data and information between computers, routers, switches and storage area networks . These cables are essentially the carrier or media through which data flows.
What are three characteristics of UTP cabling?
The following summarizes the features of UTP cable: Speed and throughput—10 to 1000 Mbps. Average cost per node—Least expensive. Media and connector size—Small. Maximum cable length—100 m (short)
What is cabling structure of LAN?
Telecom rooms on each floor are then connected together by backbone cabling (also called vertical cabling for floor to floor connections). These backbone cablings typically are done from floor to floor to floor. What Is Structured Cabling For Computer LAN Networks? • Network Time Synchronization & Accurate Time Server • All About Wireless Routers » More on Networking
How many types of network cables are there?
To connect two or more computers or networking devices in a network, network cables are used. There are three types of network cables; coaxial, twisted-pair, and fiber-optic.
What is the maximum allowable distance for horizontal wiring?
Under TIA/EIA-568-B, maximum allowable horizontal cable distance varies between 70m and 90m for twisted-pair cable types, depending upon patch cord length and gauge.
What occurs when a collision happens on a network?
A collision occurs on your network when something happens to the data sent from the physical network medium that prevents it from reaching its destination. Mainly, it encounters another signal from another host on the network that yields a resulting useless signal on the network when the signals combine.
What is the maximum length you can run horizontal station cable?
What is the minimum amount of voltage required to damage an electrical component?
Static electricity can damage electronic equipment without the technician’s knowledge. The average person requires a static discharge of 3,000 volts before he or she feels it. An electronic component can be damaged with as little as 30 volts.
What is a defining characteristic of a bus topology based network?
What is a defining characteristic of a bus topology based network? a. Devices are connected to two adjacent devices, and communication priority is granted by a token. b. Devices are connected directly to a centralized networking device, known as a network switch.
At what layer of the OSI model does a network switch normally operate?
data link layer
