Optical Modulators
The Nano-speed Broadband Variable Fiber Optical Attenuator (NSBA) provides electrical control of optical power using a patent-pending configuration activated by a voltage signal. Its solid-state optical crystal design eliminates mechanical movement and organic materials, ensuring ultra-high reliability and fast response times. The NSBA supports a wide wavelength range and is packaged with a driver that includes an SMA 0-5V control input and a 12V power supply input. It is bidirectional, with two configurations: normally-transparent, where light passes through without applied voltage, or normally-opaque, where light is blocked without voltage. The wavelength range and attenuation levels depend on the number of electro-optic crystal stages, while response speed is influenced by attenuation level and driver power. Small attenuation levels can achieve response speeds up to MHz.

Technical FAQ
Fiber Type: SMF-28, Hi1060, HI780, PM1550, SM600, SM800, PM850, PM780, PM630, PM980, Special · Fiber Cover: Bare fiber, 900um tube, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Center Wavelength: 1060nm, 2000nm, 1310nm, 1550nm, 1625nm, 850nm, 780nm, 650nm, 550nm, 450nm, Special. Check the Optical Modulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
