Intended for commissioning and lighting channels in dense wavelength-division multiplexing In fibre-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes multiple optical carrier signals on a single optical fibre by using different wavelengths (colours) of laser light to carry different signals. (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM.

FTB First Time Buyer (housing) 9310 Channel Selector enables non-intrusive, low-loss and high-isolation channel filtering. Typically used with the FTB-8000 SONET/SDH 2.5-Gbps or 10-Gbps tester, the high-precision instrument allows network operators to select and isolate-with insertion loss levels at 4 dB--any ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. DWDM channel in the C-band for bit-error-rate testing and protocol-layer analysis. The channel selector and SONET/SDH tester can also be combined with the FTB-5240B optical spectrum analyzer to provide a one-stop test solution.--EXFO
