Which of the following cable should not be used for structured cabling installation : UTP, STP, Fiber-optic, Coax.
Coax.
What enables you to use multiple NIC in a computer to achieve a much faster network speed?
Bonding.
How many pairs of wires are in a Cat 5e cable?
4.
A _____ organizes and protects the horizontal cabling in the telecommunication room.
Patch panel.
Which of the following would never be seen in an equipment rack : Patch panel, UPS, PC, all of the above may be seen in a equipment rack.
All of the above may be seen in a equipment rack.
What are patch cable used for?
To connect the patch panel to the switch and to connect the DVO to the client’s PC.
What two devices enable you to pick a single cable out of a stack of cable?
Tone generator and tone probe.
Rack mounted equipement has a height measured in what unit?
U (1.75 inches).
What are the two type of copper that you’ll find in UTP?
Solid core and stranded core. The solid core has a better conductivity but is less resilient, it should be used in stuctrured wiring. Stranded core has poor conductivity but better resilience, it should be used a patch panel and to connect clients to their DVO.
What is an IDF?
An IDF (Intermediate Distribution Frame) is a network distribution frame that serves as an interconnection point between the main distribution frame (MDF) and various network devices, such as switches, within a building or campus. The IDF is strategically located to reduce cable lengths and simplify network connectivity.
IDFs are commonly found in large buildings or organizations with extensive networking needs. They house network equipment, patch panels, and sometimes network switches. The cabling infrastructure from different parts of the building is terminated at the IDF, providing a centralized and organized location for managing network connections.
The use of IDFs in a network design helps improve network performance, ease of maintenance, and scalability by distributing network connectivity more efficiently throughout a facility.
What is the most common type of patch panel used today?
110 block.
What is a demarc?
It’s the logical and physical location were the user’s responsability starts and the ISP’s responsability stops.
What device usually sits at a demarc?
Network Interface Unit (NIU), Network Interface Box (NIB), Network Interface Device (NID).
What is a CPE?
CPE (Customer Premises Equipment) refers to network devices and equipment located at the customer’s premises that connect to a service provider’s network. CPE is used to establish communication and provide access to services, such as internet connectivity, within a customer’s home, office, or business.
Common examples of CPE include routers, modems, switches, and access points. In the context of telecommunications, a CPE device can also include equipment like telephones, fax machines, or set-top boxes for television services.
CPE plays a crucial role in bridging the customer’s network with the service provider’s infrastructure, enabling the delivery of various communication services. It acts as the interface between the customer’s devices and the wider network, facilitating data, voice, or video transmission based on the specific services provided by the telecommunications or internet service provider.
What’s the name of the main patch panel in the MDF. The one that connects to the IDFs.
It is the vertical cross connect.
