Additional kit for multiplexing

Wavelength division multiplexing involves multiplying transmission channels by increasing the number of wavelengths carried in the same fiber. This complementary set (requires the main Optical Transmission kit for bench ref. 202 945) allows for the transmission of 2 channels (at 650 and 405 nm) and studying their reception: either by selective suppression with colored filters, or by dispersion with a grating. It allows for measuring: - The laser wavelength using the grating pitch - Crosstalk/rejection from one channel to the other

Composition:
▪ 1 adjustable blue laser (ref.204598)
