In reviewing specifications of fiber-optic devices, some calculations 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

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.

Conversion Between Frequency and Wavelength

Determine Channel Frequency or Wavelength

Note: The channel spacing can be positive or negative, depending on ascending or descending direction of wavelength

Conversion Between Power in mW and Power in dBm

Note: The following tools can be used to convert between relative power to a reference and power difference in the unit of dB.
