Variable Optical Attenuators
The Nano-Speed Premium Variable Fiber Optical Attenuator (NPOA) provides fast electrical control of optical power. It utilizes special electro-optic crystals that feature lower driving voltage, faster response, and broader wavelength coverage compared to the standard NSOA. This is achieved through a patented configuration activated by a voltage electrical control signal. The solid-state optical crystal design eliminates mechanical movement and organic materials, ensuring high reliability and fast response with minimal mechanical footprint. The NPOA Series Variable Optical Attenuators are designed to meet the most demanding operational requirements, offering ultra-high reliability and fast response times, as well as vibration insensitivity. Our also provides customized electronic designs to meet special control requirements and applications.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
High Speed Premium Variable Fiber Optical Attenuator 350-2400nm, 35dB: Optical power control depends on preserving the optical budget through the complete path. The 1550nm, 780nm, 850nm, 1310nm, 1060nm wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28, HI1060, HI780, PM850, PM1550, PM980) must match the connected components.

Technical FAQ
Fiber Type: SMF-28, HI1060, HI780, PM850, PM1550, PM980 · Fiber Cover: 900um Tube, Benchtop. 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.
Wavelength: 1550nm, 780nm, 850nm, 1310nm, 1060nm. Check the Variable Optical Attenuators 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.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
