0-30dB Single-Channel Standard MEMS Variable Optical Attenuator with WDL and PDL Control

The FT-3953 from F-tone Networks is a single-channel standard MEMS variable optical attenuator with low wavelength dependent loss and polarization dependent loss for power control applications. Based on a micro-electro-mechanical mechanism with simple direct voltage drive, it comes in normally-open or normally-closed configurations with an optional integrated tap. It covers 1310, 1490 and 1550 nm windows with 30 dB attenuation range and 0.8 dB insertion loss. At 10 dB attenuation, PDL stays within 0.15 dB, WDL within 0.2 dB and temperature dependent loss within 0.4 dB. Return loss is 45 dB and response time is 5 ms. The device operates from -5 to 75 degrees C and is compliant with Telcordia GR-1209 and GR-1221 reliability standards.
