  equipment housing
• Request specifications of line parameters
• Most important points for decision
• Monthly price
• DF length
• Optical parameters (attenuation, chromatic
  dispersion, PMD)

  (if price is relatively high, prefer shorter
  period, before end of the period re-procure)

  relevant standards (geometrical, optical,
  mechanical)

  measurement

  payment
