Answer 4

Duplex

Question 5

The TIA/EIA cabling standard sets out A to B patch cord to __________ orientations

Answer 5

port

Question 6

Fiber optic connector finishing type that uses a flat polish for the ferrule. Also known as ____________________

Answer 6

Physical contact (PC)

Question 7

Fiber optic connector finishing type that uses a flat polish for the ferrule. Also known as _____________________(UPC).

Answer 7

UltraPhysical contact (UPC)

Question 8

Fiber optic connector finishing type that uses an angled polish for the ferrule.

Answer 8

Angled Physical contact

Question 9

______________ cannot be mixed with PC or UPC. These connectors are usually deployed when the fiber is being used to carry analog signaling, as in Cable Access TV (CATV) networks.

Answer 9

Angled Physical Contact (APC)

Question 10

The space where user equipment is located and connected to the network, usually via a wall port

Answer 10

Work-Area

Question 11

Connects user work areas to the nearest horizontal cross-connect. A cross-connect can also be referred to as a distribution frame

Answer 11

Horizontal Cabling

Question 12

_______________ is so-called because it typically consists of the cabling for a single floor and so is made up of cables run horizontally through wall ducts or ceiling spaces.

Answer 12

Horizontal cabling

Question 13

Connects horizontal cross-connects (HCCs) to the main cross-connect (optionally via intermediate cross-connects). These can also be described as vertical cross-connects, because backbone cabling is more likely to run up and down between floors.

Answer 13

Backbone Cabling

Question 14

Houses horizontal cross-connects. Essentially, this is a termination point for the horizontal cabling along with a connection to backbone cabling.

Answer 14

Telecommunications Room

Question 15

Special types of equipment rooms marking the point at which external cabling (outside plant) is joined to internal (premises) cabling

Answer 15

Entrance Facilities / Demarc
