  • Polarization-maintaining fiber optic attenuator

    Polarization-maintaining fiber optic attenuator

    The 780nm Polarization Maintaining In-Line Variable Optical Attenuator (PM In-Line VOA) is an optical device used to precisely adjust the power of 780nm optical signals while ensuring that the polarization state (Polarization Maintaining, PM) of the optical signal remains unchanged. We offer SM and PM electronic VOAs that provide control of the output power with FC/PC or FC/APC connectors. All input and output fibers are polarization maint ining to maintain the polarization state of the light. It is. eful tool for the optical components and systems test.


  • Sensitivity Measurement of Optical Attenuator

    Sensitivity Measurement of Optical Attenuator

    Sensitivity is the minimum average optical power in dBm to achieve a desired bit-error-rate (BER). Always compare back-to-back (transmitter directly to receiver) with maximum fiber length. This parameter directly impacts the range and performance of RF communication systems. Test setups often include signal generators, attenuators, and BER analyzers for. Sensitivity is defined as how weak an input signal can get before the BER exceeds a specific number as defined by MSA standards. 3 standard defines a series of procedures to test the correct operation of optical transceivers at the physical layer to ensure minimum required performance and interoperability (see Figure 1). Sensitivity is a critical specification as it determines how far away you can receive a communication signal or detect a target, or how much (expensive) transmitted power. Keysight optical attenuators provide precise control of optical signal power for accurate and repeatable optical component testing.
