Individual channels have a 30dB linear attenuation range with better than 0.1dB resolution, and operate using a 5V d.c. supply. A 45dB blocking function is also available. Insertion loss is 0.8dB, and the PDL is less than 0.2dB. These excellent optical properties, combined with small size and high optical input power threshold will enable these devices to be used in a wide range of applications. These include EDFA control, DWDM system transmitter or receiver signal level adjustment, and OADM level adjustment or channel blocking. The OVA is not affected by external vibrations or mechanical shocks, and is hermetically sealed to ensure long term reliability. Samples are currently available for testing with volume production starting in January.

Santec's
new MEMS based OVA component provides a compact, low cost, electronically
adjustable optical attenuator for WDM system integration. The unit
has been specifically designed to overcome technical and reliability
issues found in similar devices, whilst maintaining functional and
mechanical compatibility. It is available in 1, 4 and 8 channel
packages.
