1. Reference Conditions:
• Power level 10 µW
(-20 dBm), continuous wave (CW)
• Parallel beam, 3 mm spot diameter on the
center of the detector
• Ambient temperature 23 °C ±5 °C

over one year, add ±0.6% over two years)
• Spectral width of source ≤ 10 nm (FWHM)
• Wavelength setting at power sensor cor-
responding to source wavelength ±0.4 nm
2. Operating Conditions:
• Parallel beam, 3 mm spot diameter on the
center of the detector or connectorized fiber
with NA ≤ 0.2 (straight connector, options
C01/C02 also with angled connector ≤ 8°)
• For NA > 0.2 add 1%
• Averaging time 1 s
• Within one year after calibration,
add 0.3% for second year
• Zeroing required
3. All states of polarization at constant wave-
length (1550 nm ±30 nm) and constant
power, straight connector, T = 23 °C ±5 °C.
For angled connector (8°) add ±0.01 dB typ.

fixed state of polarization
• Temperature 23 °C ±5 °C
• Linewidth of source ≥ 100 MHz

• In case of decreasing power, allow
time for stabilization of the reading
(about 5 s per dB change)
