EigenLight Power Monitor-Attenuator Model 410

The EigenLight 410 is a Power Monitor-Attenuator (PMA) from EigenLight’s Series 400. It integrates both a variable optical attenuator and an inline optical power monitor into one compact device.

Key Features:

• 40 dB variable attenuation

• Power measurement range: –50 dBm to +16 dBm

• Provides absolute or relative power readout, with dual LCD displays

• Auto power on/off, triggered by light (no manual switch needed)

• Highly optically passive, it exhibits:

  • Low insertion loss (< 1.4 dB measured)

  • Low polarization-dependent loss (< 0.2 dB)

  • Good directivity (> 20 dB)

• Optical interface: SC/APC

• Typical operating wavelength range: 1280 – 1580 nm; calibration at 1310 nm and 1550 nm
