The Multi-Pump WDM from Gould Electronic Inc.'s Fiber Optics Div. is a narrow-spaced wavelength division multiplexer that can be used to combine multiple wavelengths into a single fiber in fiber amplifiers. It has been optimized for multiple wavelengths in the 1480-nm region with 20-, 10-, 7- or 5-nm spacing. Manufactured using a fused biconical taper process, it features 0.25-dB insertion loss, 15-dB isolation, 0.2-dB polarization-dependent loss and ±0.25-nm passband.
