Power Monitor-Attenuators (PMAs)

Power Monitor-Attenuators (PMAs) - Series 400

EigenLight's Series 400 Power Monitor-Attenuators (PMAs) combine the power control capability of a variable attenuator with the measurement capability of an inline power monitor. With a single compact device you can now vary power levels and simultaneously see the absolute optical power being delivered to your lightwave system or fiber optic test set.

Series 400 PMAs are optically passive, featuring low insertion loss, low polarization-dependent loss, and high return loss. Use these devices in place of conventional attenuators for in-line control and monitoring in the field, factory or laboratory.


FEATURES
