Functional description: Laying SMF cable with the property Cable Status - Designed and predefined number of buffer tubes and fibers.
 


SMF Cable c x v command enables the laying of SMF cable with predefined properties.
By laying in this way, you’ll get the cable with the following properties:


Properties


Optical Cable:

  • Cable type - Custom
  • Fiber type - Single-mode
  • Coating type - (default coating type, defined in the system settings)
  • Reinforcement type - (default reinforcement type, defined in the system settings)
  • Number of buffer tubes  - (c - depends on the used command)
  • Number of fibers - (v - depends on the used command)
  • Waveband  -  (default waveband, defined in the system settings)
  • Attenuation (db/km) - (default attenuation, defined in the system settings)
  • Chromatic dispersion (ps/nm·km) - (default chromatic dispersion, defined in the system settings)
  • Cable status - Designed
  • Pathway type - Underground
  • Year built - (current year is offered)

Structural features:

  • With fibers in tubes - (yes/no - defined in the system settings)
  • Slotted core cable - (yes/no - defined in the system settings)
  • Filled cable - (yes/no - defined in the system settings)
  • With aramid fibers - (yes/no - defined in the system settings)
  • Without metal elements - (yes/no - defined in the system settings)

FO cable length:

  • Trench length (m) - length obtained from the drawing
  • Sinuosity (%) - (default sinuosity, defined in the system settings)
  • Sinuosity  (m) - automatically calculated on the basis of the previous item
  • Slack loop length (m) - the sum of all cable's slack loop lengths
  • Length  (m) - length calculated based on the previous items related to length (displayed on the cable label, if the fixed length is not entered)
  • Fixed length - 0.0 (as-built length)(entered by the user based on the on-site data and displayed on the cable label, if entered)
  • Optical length - 0.0 (entered by the user based on the on-site data (OTDR measures))

TCG Global Properties:

  • TCG Object Identifier - (identification number)
  • Note - (write an arbitrary note that refers to the selected FO cable)
  • Owner - (infrastructure owner)
  • User - (infrastructure user)

These properties can be changed through the Properties window (Figure 1).


Procedure of laying cables

The laying procedure is the same for all cables.
The only difference is in the properties assigned to the cable after drawing.
The procedure is described on Laying FO Cable page.

Laying FO cables is possible only between the nodal elements of fiber optic network:

  • Splice Point (Optics)
  • Optical Distribution Frame (ODR)
  • OTB (Optical Termination Box)
  • Patch Panel
  • IPAN
  • FO router
  • FO splitter
  • ...
Clarification:

If during the cable laying, to the program’s request to select the nodal element you click on an element that doesn’t belong to FO network (e.g. manhole or copper DT), the program will simply ignore it until you select one of the abovementioned FO elements.
