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.
