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, wave-
length 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 proce-
dures. 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.

1. Values are referenced without connector loss.
2. Temperature Sensitivity Coefficient ~0.002dB/°C at the range of -5 to 75°C
3. Operating temperature range changes to -5 to 75°C in P2, P3 package and all package with connectors
4. The mechanical tolerance should be +/- 0.2 mm on all package dimensions unless otherwise custom specified.
