Polarization-Maintaining (PM) In-Line Variable Optical Attenuator

Polarization-Maintaining (PM) In-Line Variable Optical Attenuator

This Polarization-Maintaining (PM) In-Line Variable Optical Attenuator (VOA) offers low insertion loss, high attenuation range, and continuous adjustability with excellent reliability and stability. It operates at wavelengths of 1310 nm and 1550 nm, providing precise attenuation control from 0.6 dB to 60 dB.

Ideal for optical communications, fiber sensing, and EDFA power control applications, the attenuator ensures high return loss and polarization extinction ratio. Custom configurations including fiber type, connector type, and fiber length are available to meet specific system requirements.
