Short description
This contribution shows the interrogation of 4000 serial fiber-Bragg gratings (FBGs) by means of a hybrid code-division multiplex (CDM) - wavelength-division multiplex (WDM) scheme. A strain measurement shows no influence of a strained WDM-section to another non-strained WDM-section. Polarization effects are diminished by the implementation of a semi-conductor optical amplifier.
