Click 'Spec Sheet' for available configurations/part#


The NS Series fiber optical phase 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.
