IEC Technical Specification 62129-3 Replaced

IEC TS 62129-3:2014, which is a technical specification, describes the calibration of optical frequency meters. It is applicable to instruments measuring the optical frequency emitted from sources that are typical for the fibre-optic communications industry. It is assumed that the optical radiation will be coupled to the optical frequency meter by a single-mode optical fibre. Keywords: calibration of optical frequency meters, single-mode optical fibre
