Fiber-Optics Calculators  

When reviewing DPSK, DQPSK, interleaver, tunable filter, OPM and OCM specifications of fiber-optic devices, some calculations in relation to wavelength, frequency, power, etc.are repeatedly used. These calculations may include:

  • Conversion between frequency and wavelength
  • Determine channel frequency or wavelength
  • Determine channel plan
  • Conversion between power in mW and power in dBm
  • Conversion between relative power to a reference and power difference in dB
  • Conversion between transmission in percentage and insertion loss in dB

We provide these calculators for your convenience. If you feel these useful and need other calculation tools, please let us know by writing to info@optoplex.com.
