When associated with a Vector Network Analyser, they make a high performance and easy to use piece of test equipment for the characterisation of photoreceivers or any high speed optoelectronic device.
The Photline ModBox-VNA series incorporates a low noise laser source and a modulation stage based on a high bandwidth LiNbO3 modulator with an automatic bias control circuit.
Other models in the ModBox range provide reference transmitters for telecommunication, analogue (RFoF), and pulsed applications.
The main markets for these fibre optical modulators are:
- optical communications
- sensor technology and instruments
- defence
- research
The range of standard products includes a comprehensive line of intensity and phase modulators for wavelength ranges of approximately 1000, 1300, and 1550nm. These devices work at frequencies up to 40GHz. Electronic RF drivers, bias controllers, and customised solutions are also available.
