NanoSpeed™ Fiber Optical Polarization Switch Low Drift

SKU: NSPS

The NanoSpeed™ Series polarization switch swiftly changes the incoming State of Polarization (SOP) between two orthogonal SOPs. The version uniquely features low optical loss and low drift, fast response, and high optical power handling. This is achieved using drift-compensating electro-optical control technology. The unit is integrated with a driver and packaged in a metal box. The switch uses a 5V TTL signal via an SMA input and a 12V power supply that is wall-pluggable. The switch’s rise and fall times are inherently linked to the properties of the crystal, while the repetition rate is determined by the driver. Some frequency response issues may occur due to device resonances.

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 intrinsically bidirectional. 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 are intended to be operated at a repetition rate >1Hz. The NS series switches respond to a control signal with any arbitrary timing. 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.
