PM Polarization Maintaining Variable Optical Attenuator 1 Channel 1310nm 1480nm 1550nm 980nm 1064nm 780nm 850nm

This PM VOA is a single-channel Variable Optical Attenuator designed specifically for Polarization-Maintaining (PM) fiber systems. It supports multiple common wavelength bands, including 1310/1480/1550nm, 980/1064nm, and 780/850nm. Utilizing PM Panda Fiber, the product delivers excellent polarization-maintaining performance and stable attenuation control capabilities, making it suitable for applications such as optical power adjustment, link balancing, signal calibration, and system protection. Its maximum insertion loss is remarkably low—ranging from 0.5dB, 0.6dB, to 0.7dB depending on the specific configuration—while offering a maximum attenuation range of up to 60dB and a return loss of up to 55dB. This allows for highly flexible optical power management while simultaneously ensuring polarization stability. The product supports either 250μm bare fiber or 900μm blue loose-tube cabling, with a standard fiber length of 100cm. Connector options include FC/APC, FC/UPC, or custom configurations. Featuring a compact structure, it is ideally suited for integration into experimental platforms, telecommunications equipment, and OEM modules.
