The NS Ultra-Fast Series fiber optical switch is based on a patented electro-optical configuration, featuring low optical loss and wide temperature operation with built-in compensation. The NS fiber optical switch meets the most demanding switching requirements of continuous operations over 25 years and non-mechanical ultra-high reliability (passed Telcordia and space qualifications).

The NS Series switch is mounted on a specially designed electronic driver using a 5V TTL control signal through SMA input and a 25V power supply (wall pluggable).
