Product Info


This fiber modulator is a high switching speed module. It operates as a lossless optical isolation switch, a full-range variable optical attenuator (VOA), or an optical shutter.

Key Features :

  • Lossless device
  • High dynamic range : >48 dB
  • Very low noise and stable signals
  • High speed : down to 500 ps rise/fall time
  • User design pulse shape (SOM-Shape only)
  • High extinction ratio : >50 dB
  • No wavelength evolution along the pulse duration

Applications of this fiber modulator include laser seeding, LIDAR testing, etc.

The GUI software lets the user have total control of all module functions. It includes several libraries for software integration (LabVIEW VIs, DLLs, Hexa etc.)

This fiber modulator works alone or in series with other products in our range like :

Fiber optic modulators comparison
SOM are SOA-based fiber modulators devices which have many advantages compared with other fiber modulation technologies

 

See our detailed Tutorials on :

  • High speed fiber modulation : Fiber modulation basics
  • Fiber lasers : Fiber laser basics

SOM is an alternative to Acousto Optics Modulators (for example G&H) or Electro Optics Modulators (for example iXBlue).
