Agilent 81628B
1 Reference Conditions:
• Power level 10
µW (-20 dBm), continuous wave (CW)
• Parallel beam, 3 mm spot diameter on the center of sphere input
• Ambient temperature 23 °C ± 5 °C
• On day of calibration (add
± 0.3% for aging over one year; add ± 0.6% over two years)
• Spectral width of source < 10 nm (FWHM)
• Wavelength setting at power meter must correspond to source wavelength ± 0.4 nm
• Humidity 50% ± 10%
2 Operating conditions:
• Parallel beam, 3mm spot diameter on the center of sphere input or connectorized fiber
with NA
≤ 0.2 (straight connector)
• For NA > 0.2, add 1%
• Within one year after calibration, add 0.3% for second year
• Operating temperature range as specified; humidity: <80% and non-condensing
3 All states of polarization at constant wavelength (1550 nm ± 30 nm) and constant power.
4 Conditions:
Wavelength 1550 nm ± 30 nm, fixed state of polarization, constant power, Temperature
23°C ± 5°C,
Measurement time
≤ 3 min.
5 At constant temperature (
∆T = ± 1°C), zeroing required.
6 Averaging time 1s, T = 23°C ± 5°C, observation time 300 s. Wavelength range 970 - 1630 nm.
Thermal drift at 38 dBm, exposure time 30 min:
Recovery time 10 min:
≤ 30 nW
30 min: ≤10 nW
7 For optical power > 30 dBm the maximum operating temperature is limited to 35 °C
8 Wavelength must not be equal to any water absorption line.
*Attention
Safety Note:
For optical power higher than 34 dBm the attached heatsink MUST be used!
For continuous optical power or average optical power higher than 38 dBm the
connector adapters will get warmer than permitted according to the safety standard
IEC 61010-1.
The Agilent 81628B Optical Head can handle power up to 40dBm, however, operation
above 38 dBm is at the operators own risk. Agilent Technologies Deutschland GmbH
will not be liable for any damage caused by operation above 38 dBm.
