    A pump wavelength-division multiplexer (WDM) for fiber amplifiers provides two, three, or four channels in the 980-nm window.

    A pump wavelength-division multiplexer (WDM) for fiber amplifiers provides two, three, or four channels in the 980-nm window. The WDM module is based on the company’s cascaded fiber technology. The product’s beginning wavelength is user-selected, with channel spacing of 3.2 nm. The device can increase the pump power more than twice.
