Fiber Optical 90º Polarization Modulator/Switch – NanoSpeed™
60ns rise/fall, 500MHz, low loss, bidirectional, 850nm to 1620nm, 0 to 70 °C
The NS Series fiber optical polarization modulator/switch is based on a patented electro-optical configuration, featuring low optical loss and wide temperature operation with built-in compensation. The device dynamically controls the optical phase of the transmitting light, meeting the most demanding requirements of continuous operations over 25 years and non-mechanical ultra-high reliability (passed Telcordia and space qualifications) The device is bidirectional in which the input and output ports are interchangeable.
This device is mounted on a specially designed electronic driver using a 5V TTL control signal through SMA input and a 12V power supply (wall pluggable). The maximum phase change can be adjusted by a pot on the board
