DIN EN 62129-2:2012-03

This part of IEC 62129 is applicable to instruments measuring the vacuum wavelength or optical frequency emitted from sources that are typical for the fibre-optic communications industry. These sources include Distributed Feedback (DFB) laser diodes, External Cavity lasers and single longitudinal mode fibre-type sources. It is assumed that the optical radiation will be coupled to the wavelength meter by a single-mode optical fibre. This standard describes the calibration of wavelength meters to be performed by calibration laboratories or by wavelength meter manufacturers. This document is part of the IEC 62129 standard series on the calibration of wavelength/optical frequency measurement instruments. Calibration of optical spectrum analyzers is described in IEC 62129. The standard refers to ISO/IEC guides 98 and 99 and is directed at manufacturers and users.
