IT 113 Cabling Exercise 1
The Bottom Line
The Identify the key industry standards necessary to specify, install, and test network cabling.
Master it
What industry standards body and standards series numbers do you need to reference for Ethernet applications and cabling?
Answer:
The IEEE maintains the industry standard for Ethernet protocols (or application). This is part of the 802.3 series of standard and includes applications such as 1000Base-T, 1000Base-SX, 10GBase-T, and 10GBase-SR.
A completely updated version of this standard was released as ANSI/TIA/EIA-568-B in May 2001 that you also need to reference for Ethernet applications and cabling.
Understand the different types of unshielded twisted-pair (UTP) cabling.
Master it
What are the different types of Category 6 cable and what should be recommended for this network?
Answer:
Category 6, and Category 6A or Augmented Category 6 (recognized cable type in ANSI/TIA-568-C). Category 6A should be recommended for this network. Because, its intended use is for 10 Gigabit Ethernet.
Understand the different types of shielded twisted-pair cabling.
Master it
What cable would you recommend to offer the best shielding performance?
Answer:
The best possible cable would be fiber since EMI has no effect on fiber optics and can easily do 10GBase-T. Otherwise, I would use Category 6A that is STP because it would help protect against EMI and can operate at 10GBase-T networking.
Determine the uses of plenum and riser-rated cabling.
Master it
What type of cable would you use for:
a) The horizontal spaces?
b) The vertical links?
Answer:
The plenum is the space between the false ceiling and the structural ceiling, when that space is used for air circulation, heating ventilation, and air-conditioning (HVAC). Typically, the plenum is used for returning air to the HVAC equipment.
The riser is a vertical shaft used to route cable between two floors.
The National Electrical Code permits plenum cable to be used in the riser, but it does not allow riser cable
