Optical Power Leveler KI5010-APC (1270~1330 nm, APC)
A combined power meter, variable optical attenuator and set-point controller provides automatic power levelling in one single-direction or bi-directional fiber transmission line. It would typically be used instead of a fixed attenuator.
Fitted to a 35 mm DIN rail, and provided with a 12 - 48V power supply, this is an easy, reliable and unique solution to control transmission problems caused by varying receiver power levels, and is typically useful to solve optical power management issues in SDN or "white box" type installations.
No telemetry link is required. Please enquire for alternative optical configurations and specifications.
