Polarization Maintaining MVOA PM Variable Optical Attenuator 1310 1550 980 1060nm High Precision Low Loss For Optical Test Lab And Power Calibration
The Polarization Maintaining MVOA is a polarization-maintaining variable optical attenuator (PM MVOA) specially designed for polarization-sensitive systems. It enables continuous and precise control of optical power through accurate attenuation adjustment. The product covers the 1310nm / 1550nm communication bands and the 980nm / 1060nm laser bands, with a typical attenuation range of 0.6 to 50/60 dB, a low intrinsic insertion loss as low as 0.6 dB, while maintaining a high extinction ratio of ≥20 dB (typical 22 dB) and a return loss of ≥50 dB. The device features a highly reliable mechanical structure and polarization-maintaining fiber, making it ideal for fine power control in optical passive device test platforms, laboratory optical paths, and optical communication system test links.

Main body size 26 * 18 * 8 mm (L*W*H), compact metal package, easy to integrate within modules or chassis.
Optical fibers extend from both sides of the module body, with mounting holes on the top surface for convenient screw fixing on trays or optical boards.
Mechanical drawings show an overall length (including stress relief structures) of approximately 98 mm, main body height of 8 mm, width of 18 mm, and small thickness, suitable for high-density layouts.
Standard single-core polarization-maintaining fiber pigtail, length and jacket can be configured according to selection information (250 μm bare fiber / 0.9 mm / 2.0 mm / 3.0 mm).
