ATN-A11-20 - Corning Cable Systems

Corning Cable Systems offers In -Line, Flat Wavelength

Optical Attenuators that are easily inserted between the

connector and adapter in an “in -line” configuration and

are compatible with SC, ST® Compatible, FC, MU, LC

and angled SC and FC connectors.A fundamental ele-

ment of these Corning Cable Systems attenuators is the

zirconia ferrule containing a specially selected attenuat-

ing fiber. This special fiber minimizes the effect of modal

interference and gives the component a flat spectral re-

sponse. It is extremely stable over the wavelength range

of 1260 to 1360 nm and 1430 to 1580 nm.These in -line,

flat wavelength attenuators are available in Ultra PC (≤ -

55 dB) and Angled PC (≤ -65 dB) finish to meet the most

demanding network reflectance requirements.
