High Speed Fiber Optical Polarization Switch

SKU: NSPS

The NanoSpeed™ Series polarization switch can quickly switch the incoming SOP between two orthogonal polarization states (SOPs). This is achieved using our patented non-mechanical configurations with solid-state all-crystal designs, which eliminate the need for mechanical movement and organic materials and are activated via an electrical control signal. The NS fiber optic switch is a fast switch device featuring very low loss, fast response, ultra-high reliability, and high optical power handling. The input is PM fiber. The output could be either PM or SM fiber. For PM fiber, the polarization is aligned with the slow axis. The switch is intrinsically bidirectional and selectable for polarization-independent or polarization-maintaining by the fiber type.
Agiltron’s SWDR driver is highly recommended for this polarization switch, by which the switch can be driven by a 5V TTL signal through the SMA input and a 12V power supply (wall-pluggable).
The rise/fall time is intrinsically related to the crystal properties, and the repetition rate is associated with the driver. There are poor frequency response sections due to the device resonances. The NS devices are shipped mounted on a tuned driver.
The NS series switches respond to a control signal with any arbitrary timing with a 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 dual-stage configuration increases the extinction ratio or cross-talk value.
