The NSSI (NSS5) series of NanoSpeed™ electro-optical switches uniquely features low optical loss and high on-off extinction of 50dB, low optical loss, fast response, and high optical power handling. This is achieved using compensating electro-optical control technology that significantly reduces drift to achieve a high on/off ratio at high speed. It cascades several switches on a PCB board with a cover. Control is 5V TTL via an SMA signal input port, and power is 12V DC (a wall pluggable is accompanied inside the shipping box). We meet the most demanding reliability requirements for undersea, space, and continuous switching with a longevity of over 25 years. Our switch is intrinsically bidirectional and selectable for polarization-independent or polarization-maintain by the fiber type. No optical signal loss occurs during the switching in which optical power is transferred continuously from one port to another (see graph at the end).
The Low-Drift series of NanoSpeed™ devices is intended to be operated at a repetition rate >1Hz.
The NS series switches respond to a control signal with any arbitrary timing with frequency from DC up to MHz. The switch is usually mounted on a tuned driver before shipping. The electrical power consumption is related to the repetition rate at which the switch is operated.
The device may have some drift over time when operated at a zero switching rate.
The dual-stage configuration increases the extinction ratio or cross-talk value.
