High Speed Non-Drift 1×1 Fiber Optical Switch: 100ns, 75dB On/Off

SKU: NSN4

The NSSI series of NanoSpeed™ electro-optical switches delivers low optical loss, over 70 dB on/off extinction, little drift, fast response, and high optical power handling through drift-compensating control technology. Built by cascading multiple switches on a PCB with a protective cover, they operate via 5 V TTL control (SMA input) and a 12 V DC supply. Designed for exceptional reliability — including undersea, space, and continuous-duty applications with lifetimes exceeding 25 years — the intrinsically bidirectional switches are available in polarization-independent or polarization-maintaining fiber configurations and transfer optical power seamlessly between ports with no loss during switching. The Low-Drift series is optimized for repetition rates above 1 Hz, responds to arbitrarily timed control signals, and exhibits power consumption proportional to switching rate, with some drift occurring only when operated at zero switching rate.
