Multimode attenuation standards compliance
For LED sources and LTS

The following standards may apply to evaluation of multimode attenuation:

• ANSI/TIA/EIA-526-14-A: Optical power loss measurements of installed multimode fiber cable plant, 1998.
• IEC-61280-4-1 Ed 1.0 (draft): Fiber optic communication subsystem basic test procedures - part 4.1: Procedures for cable plant and links - multimode cable plant attenuation measurement.
• ISO/IEC 14763-3: Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling.

These standards typically define:

• Use LED sources with specific Modal Power Distribution, Center Wavelength and Spectral Width characteristics.
• Tests may require one or both 850 / 1300 nm wavelengths.
• Use a two-way or bi-directional measurement procedure.
• Use of test cords (eg 1 - 3 test cord methods) and reference planes.

Kingfisher multimode instruments comply with the requirements as follows:

• Kingfisher LED sources have a near EMD Modal Power Distribution, so they provide consistent results which agree with long standing multimode measurement practice as defined in many well recognised FOTP documents.
• All Kingfisher LED sources, Loss Test Sets and Two-Way testers are compliant with traceable certification to multimode standards for: Coupled Power Ratio, Center Wavelength and Spectral Width. Applies to 50/125 cables, such as OM3 fiber types
