EM1600-OAR
Overview
These amplifiers are fully controlled by LambdaDriver^®
The LambdaDriver^® EM1600-OAR modules use an advanced management and provide power monitoring on the amplified
Raman technology for optical signal amplification, used in large optical signal as well as on the condition of the internal pumps.

EM1600-OAR incorporates parallel, independent eye-safety
mechanisms that shutdown the amplifier in the following cases:
These modules extend the single span reach by at least 50 km
