| Abstract: | Measurement results showing that the cabling loss of P2O5-doped MCVD graded-index multimode fibre increases for wavelengths longer than 1.3 ?m have been obtained. This letter investigates the cause for this loss increase. It also has been found that the loss increase is caused by P-OH bond absorption near the core-cladding boundary, where OH ions are diffused from the fused-quartz tube. |
