Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Before Milliwatts (mW)

Required number input.

After Milliwatts (mW)

Required number input.

Additional optical bend loss from through-power measurements before and after introducing a bend. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Bend Loss Decibels (dB)

The resulting bend loss decibels returned as a number.

• Fiber loss and dispersion depend on wavelength, fiber type, launch conditions, connectors, splices, bends, temperature, bandwidth, and nonlinear effects. A link budget needs explicit transmitter, receiver, aging, and engineering margins.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Antenna Radiation Efficiency

  Calculate radiation efficiency as radiated power divided by accepted power ×100. Mismatch loss before power is accepted at the antenna port is not included.

• Fiber Attenuation dB

  Compute the total attenuation of an optical fiber link from its loss coefficient and length.

• Fiber Attenuation Coefficient

  Average fiber attenuation in decibels per kilometer from launched and received optical power over known length.
