Question # 41

A building has six floors plus a basement. Each floor is 929 sq m (10,000 sq ft) and has approximately 50 CATV outlets respectively. There is a single hardline trunk cable installed from the basement headend passing through the telecommunications room (TR) on each floor. In order to maintain the LEAST signal loss passing through each telecommunications room (TR) to the next telecommunications room (TR), what device should you specify for use within each telecommunications room (TR)?

A.

Splitter

B.

Directional coupler

C.

Multiport tap

D.

Combiner

B.

Insertion loss (attenuation), return loss, and continuity

C.

Insertion loss (attenuation), return loss, and length

D.

Insertion loss (attenuation), continuity, and wiremap/strand identification

E.

Continuity, wiremap/strand identification, and propagation delay/delay skew

Question # 47

You are reviewing a building backbone design with a vertically aligned telecommunications room (TR). In the spec you note in a footnote with details that the slots at one end of the telecommunications room (TR) must be flush with the floor and the sleeves provide at the end of the telecommunications room (TR) must also be flush. In your meeting with the electrical engineering firm that has provided the spec, you make the comment that according to best practices, the MINIMUM that slots and sleeves must extend above the finished floor are:

A.

25 mm (1 in) for slots and 51 mm (2 in)

B.

25 mm (1 in) for slots and 25 mm (1 in)

C.

51 mm (2 in) for slots and 25 mm (1 in)

D.

51 mm (2 in) for slots and 51 mm (2 in)

E.

64 mm (2 1/2 in) for slots and 64 mm (2 1/2 in)

Question # 48

You have been asked to project manage a fiber cable backbone installation. In the course of the installation, you notice the fiber cable with a 25 mm (1 in) outside diameter is being installed into a small TR, and the cable is being installed into a tight corner. Based on your knowledge of minimum bend radius requirements for fiber cable, you must ensure that the MINIMUM cable bend radius of _______________ is provided when the cable installation is completed.

A.

254 mm (10 in)

B.

305 mm (12 in)

C.

381 mm (15 in)

D.

457 mm (18 in)

E.

610 mm (24 in)
