Pump dense wdm

The pump dense wavelength-division multiplexer provides two-, three-, or four-pump channels in the 980- or 1060-nm window for multiple-wavelength pumping of erbium-doped, erbium ytterbium co-doped, and praseodymium-doped fiber amplifiers. The device accommodates total pump power in excess of 1W. Standard wavelength spacing is 2.0 nm, and custom spacing is available.
