Single Window Fixed In-line Attenuators
(1310, S, C, L and C+L Band)
SWFA Series
Product Description
The Oplink fused single window wideband Fixed In-line Attenuators provide ac-
curate attenuation over wide bandwidth with high performance and high reliabil-
ity. These attenuators have excellent temperature stability, very good wavelength
flatness, very low polarization sensitivity and are available with various attenua-
tion ratios, wavelength ranges, and connector options. All devices are shown to
be able to handle high optical power up to 4W and are tested according to indus-
try standard procedures. Reliability is guaranteed through stringent tests to fully
meet Telcordia GR-1221 requirements.
