Dense Wavelength Division Multiplexing (DWDM) is an optical technology that allows transmitting across a fiber many wavelengths, which can be added and dropped by means of passive optical components. The performance of a complex DWDM network data transmission system that will find an application in the NEMO underwater neutrino telescope. The tests cover the qualification of a complete multipoint DWDM network consisting of transponders, fibers, passive optical filters, and an optical amplifier. The behavior of the network is evaluated in the final arrangement by means of Bit Error Ratio (BER) and optical signal-to-noise ratio measurements at 800 Mb/s rate.
