Santec introduces new polarization maintaining variable attenuator

Product Name: Polarization Maintaining Optical Variable Attenuator
Model: OVA-100

Santec Holdings Corporation, a leading manufacturer of advanced optical components, tunable lasers, optical test equipment, and OCT systems, announces the product launch of the polarization maintaining (PM) OVA-100 optical variable attenuator. The OVA-100 enables precise optical power control featuring high accuracy and superior repeatability.
With a PER > 23 dB, the PM OVA-100 is invisible to your application. Featuring an attenuation range of 60 or 100 dB, covering a wide wavelength range from 1200 to 1700 nm and excellent ± 0.01 dB repeatability, the PM OVA-100 is built with Panda PM fiber.
The power monitoring option can be used to auto adjust the attenuation to achieve a constant power level. The small 2U benchtop form factor can have up to 4 channels and can be integrated into a rack system using a rack mount kit. For higher channel counts, up to 8 channels, a larger 3U rack mount enclosure is available.
The OVA-100 can be seamlessly integrated into different test setups using SCPI commands via USB or Ethernet. Additionally, it features a standard front panel touchscreen for convenient local control.


  • Easy Integration: SCPI command via USB and Ethernet

  • Excellent Repeatability: ±0.01 dB

  • High extinction ratio: higher than 23 dB of PER
