DIN EN IEC 60793-1-44 VDE 0888-244:2024-06

Optical fibres

Part 1-44: Measurement methods and test procedures – Cut-off wavelength

(IEC 60793-1-44:2023); German version EN IEC 60793-1-44:2023
Class/Status: Standard, valid
Released: 2024-06
VDE Art. No.: 0800966

This part of IEC 60793 establishes uniform requirements for measuring the cut-off wavelength of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes.
This standard gives methods for measuring the cut-off wavelength for uncabled or cabled single mode telecom fibre. These procedures apply to all category B and C fibre types (see Normative references).
