The optical amplifier is a key device in today's high-capacity and long-distance optical communications networks, and evaluation of the optical amplifier noise figure (NF) and gain demands measuring instruments with excellent performance and accuracy.

The ME7890B covers both bands of C-Band and L-Band.  The ME7890B supports this need with fast and high-accuracy of the NF and gain of optical amplifier using the optical pulse probe method.

MF9619C is an optical modulator that is part of this system.
