1. Reference Conditions:
• Power level 10 μW (-20 dBm),
continuous wave (CW)
• Averaging time 1 s
• Parallel beam, 3 mm, 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 sensor must
correspond to source wavelength ±0.4 nm
• Humidity 50% ±10%
2. Operating Conditions:
• Parallel beam, Ø3 mm, 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
• Zeroing required
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. Does not include noise; zeroing required
6. Averaging time 1 s, T = 23 °C ±5 °C, ΔT ±1 °C,
observation time 300 s, wavelength range
970 nm to 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 maximal
operating temperature is limited to 35 °C
8. Wavelength must not be equal to any
water absorption line
Safety Note:
For optical power higher than
34 dBm the attached heat sink
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 81628B Optical Head can handle
optical power up to 40 dBm, however,
operation above 38 dBm is at the
operators own risk.
Agilent Technologies Deutschland
GmbH will not be liable for any
damages caused by an operation
above 38 dBm.
