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 :
- Laser driver
- Low noise laser diode driver
- Pulsed laser diode driver
- High speed laser diode driver
- 976 nm laser diode
- 980 nm laser diode
- 1064 nm laser diode
- SOA pulsed driver
- Pulse delay generator
- Pulse picker
