Popis
BS EN 60793-1-41:2010
This standard BS EN 60793-1-41:2010 Optical fibres is classified in these ICS categories:
- 33.180.10 Fibres and cables
- Method A - Time domain (pulse distortion) measurement
- Method B - Frequency-domain measurement
- Method C - Overfilled launch modal bandwidth calculated from differential mode delay (OMBc).
The main change with respect to the previous edition is the addition of a third method for determining modal bandwidth based on DMD data and to improve measurement procedures for A4 fibres. This standard should be read in conjunction with IEC 60793-1-1 and IEC 60793-1-2, which cover generic specifications.
