SKU: NSRM
The NS Series fiber optic modulator features fast amplitude modulation about 20 Mhz, low driving voltage and low optical loss. This is achieved using a patented electro-optical configuration and operating at a fixed frequency with a built-in high Q resonant circuit. Unlike other modulators, we use special electro-optical crystals of high stability that increase power handling and reduce drift/darkening. The NS fiber optic switch meet the most demanding switching requirements of continuous operations over 25 years and non-mechanical ultra-high reliability.
Our resonant EO phase modulators can be driven by a standard laboratory function generator with a Half-Wave Drive Voltage of only 15 V at 633 nm.
Custom versions are also available, with user-specified resonant frequencies from 0.1 to 100 MHz.

[1] Measured without connectors. For other wavelengths, please contact us.
[2] Cross talk is measured at 100kHz, which may be degraded at the higher repeat rate.
[3] It is defined as the rising or fall time between 10% and 90% of optical intensities.
[4] Defined at 1310nm/1550nm. For the shorter wavelength, the handling power may be reduced, please contact us for more information.
High power version available by incorporating fiber core enlargement (expensive).
