An installation crew is pulling an optical fiber cable into a riser. The cable has an outside diameter of 25 mm (1 in). As the cable is being pulled off the reel and through a pulley into the riser, you must verify that the minimum bend radius for the cable being pulled is observed. The pulley must be sized at a MINIMUM of:

  1. 254 mm (10 in)
  2. 381 mm (15 in)
  3. 508 mm (20 in)
  4. 635 mm (25 in)
  5. 762 mm (30 in)

Answer(s): B



The maximum vertical rise is the distance over which the cable is vertically self-supporting. This distance is a function of the weight of the cable and the:

  1. Sheath fire rating
  2. Number of strands of fiber in the cable
  3. Type of hangers used in the riser
  4. Type of fire stop used in the riser
  5. Cable maximum tensile rating

Answer(s): E



In the customer's environment, an ITS designer should avoid the need for optical fiber field splicing by:

  1. Installing oversized inner duct
  2. Using oversized cable trays
  3. Using pre-connectorized cables
  4. Installing a continuous length of cable
  5. Using multiple pull boxes

Answer(s): D



A campus backbone design linking two buildings requires that you install a high-fiber-count cable very quickly, using the conduit system provided. Cost is not so much an issue as urgency is to meet a service demand. Your first choice of fiber cable installation is to use:

  1. Multiple sheathed cables with field connectorization
  2. Multiple sheathed cables using pigtail connectorization
  3. Single high fiber count sheathed cable with field connectorization
  4. Single sheathed high-fiber-count cable with pigtail connectorization
  5. Single sheathed cable equipped with preconnectorized assemblies

Answer(s): E



One advantage of using preconnectorized jumpers and cables is:

  1. They are less costly than field connectorized connectors
  2. The cables are more rugged and can handle higher pull tensions
  3. They come with factory certified quality of terminations
  4. They require additional engineering time thereby providing a higher degree of reliability
  5. The technician does not need to be concerned with the water blocking components of the cable

Answer(s): C
