Fiber Optical Phase Modulator/Switch - NanoSpeed™

SKU: NSPM

The NS Series fiber optical phase modulator/switch is a device based on a patented electro-optical configuration, featuring low optical loss and wide temperature operation with built-in compensation. The device is a bidirectional two-port equipment in which the input and output ports are interchangeable. The device dynamically controls the optical phase of the transmitting light, meeting the most demanding requirements of continuous operations over 25 years and non-mechanical ultra-high reliability (passed Telcordia and space qualifications). The switch is intrinsically bidirectional and selectable for polarization-independent or polarization-maintain by the fiber type.
For high-frequency resonance configuration, the device has an integrated circuit inside that only requires a 5V AC input signal matching the resonance frequency. For lower frequency, this device can be mounted on specially designed electronic drivers of both analog and digital switching drivers using a 5V analog or TTL control signal and a 12V power supply (wall pluggable), respectively.
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 at any arbitrary time, 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.
