Technical Specifications
January 2007
Specification: describes a guaranteed product performance that is valid under the specified conditions. Specifications are
based on a coverage factor of 2 (unless otherwise stated), corresponding to a level of confidence of >95%.
Typical value: a characteristic, describes the product performance that is usually met but not guaranteed.
Generally, specifications are valid after warm-up, after zeroing, in auto-range mode (if not differently stated) and at the
stated operating conditions and measurement settings.

over one year, add ± 0.6 % over two years)

correspond to source wavele ngth ± 0.4 nm
• Humidity 50 % ± 10 %

Operating Conditions:
• Parallel beam, ∅ 3mm , center of sphere
input, or connectorized fiber with NA ≤0.2
(straight connector)
• For NA > 0.2: add 1%
• Within o ne year after c alibration, add
± 0.3% for second year

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.
