Description of the technology

The service includes extensive measurements of the customer's fiber optical line, which allows judging on the efficiency of the transmission system, eliminate existing or potential problems, and improving its performance. Certified and up-to-date high-end scientific equipment is used for the provision of services:

  1. Power Meter: EXFO EPM-50 (Canada)
  2. Chromatic Dispersion (CD) and Polarization Modal Dispersion (PMD) meters:
    • EXFO single-sided CD / PMD analyzer FTB-5700 (Canada)
    • EXFO PMD Analyzer FTB-5500 (Canada)
    • EXFO CD Analyzer FTB-5800 (Canada)
  3. Optical-time domain reflectometer: EXFO FTB-7500 (Canada)
