Single Window Fixed In-line Attenuators (1310, S, C, L, and C+L band) SWFA Series Features Wavelength Independent Low Insertion Loss and PDL High Power Handling Guaranteed Reliability Applications Flatness Adjustment Power Management Testing Instruments Single Window Fixed In-line Attenuators (1310, S, C, L, and C+L band) The Oplink fused single window wideband Fixed In-line Attenuators provide accurate attenuation over wide bandwidth with high performance and high reliability. These attenuators have excellent temperature stability, very good wavelength flatness, very low polarization sensitivity and are available with various attenuation 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 industry standard procedures. Reliability is guaranteed through stringent tests to fully meet Telcordia GR-1221 requirements. Oplink can provide customized designs to meet specialized feature applications. Also,Oplink offers modular assemblies that integrate other components to form a full functionmodule or subsystem.
