The NanoSpeedTM i-series fiber optic switches are fast switches uniquely featuring high on-off extinction of 50dB, very low optical loss, fast response, and high optical power handling. This is achieved using a patent-pending intelligent feedback electro-optical bias control technology, that maintains the optimum performance against environment variations. The NS fiber-optic switch meets the most demanding reliability requirements for undersea, space, and continuous switching with a longevity of over 25 years. The switch is bidirectional. The NS Series switch is controlled by 5V TTL signals with a specially designed electronic driver having performance optimized for various repetition rates. A wall pluggable DC power supply is accompanied by each device.
