Optical variable attenuators

OVA-100/200/210 optical variable attenuators feature wavelength ranges at 1330 and 1550 nm, and 0 to 35-dB attenuation. Return loss is greater than 70 dB, and the polarization-maintaining dispersion is less than 0.003 picoseconds. The attenuators are for optical communications, including erbium-doped fiber amplifiers and wavelength-division multiplexers; cable TV, and research and development applications.
