Calibration of fiberoptic equipment at The National Laboratory
The National Laboratory for Photometry and Radiometry offers calibration of fiberoptic equipment.
Purpose
The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competens and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.
A calibration performed at a national laboratory fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large.
Method
The scope of the national laboratory includes:
- Responsivity of fiber optic detectors or power meters (850 nm, 1300 nm, 1550 nm)
- Wavelength of fiber optical sources (600 nm - 1550 nm)
- Wavelength of optical spectrum analysers (600 nm - 1550 nm)
Calibration of power meters are performed in comparison with a reference radiometer. Calibration of wavelength is performed using absorption lines in a gas cell.
We also offer accredited calibration of:
- Length scale for OTDR
- Loss deviation for OTDR
- Pulse characteristics for OTDR
The OTDR calibrations are not performed as part of the national laboratory but have separate accreditations.
We are available for consultation with regard to fiber optic measurements and can also help with validation of equipment or measurement methods.
Deliveries
The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory or as an accredited calibration.
