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
networks.
mechanisms that shutdown the amplifier in the following cases:
1. Fiber

These modules extend the single span reach by at least 50 km

amplifiers also improve the Optical-Signal-to-Noise-Ratio (OSNR)
2. High reflection power which may be caused
in amplified long-haul networks because they do not introduce

3. Pump high temperature that may be caused
by an internal problem

As an example: If we need to transmit 10Gbps signals over a 200
km distance crossing the sea or a desert, without the possibility to
place a signal regeneration device in the middle, the only way to This unique and comprehensive safety mechanism of the EM1600-
OAR module is extremely important due to the Raman amplifier’s
