RMH6000 Preamplifiers
RMH6000 Optical preamplifiers provide low noise amplification prior to the receiver.
High Power Wideband Preamplifier
The RMH6000-R15F and RMH6000-R17F high power preamplifiers are intended for use in multi-wavelength application typically where distributed Raman amplification or a ROPA is employed at the receiving end of the span.
They provide enhanced effective receiver sensitivity with near quantum limited noise figures.

Low-Noise Wideband Preamplifier
The RMH6000-R35W preamplifier provides flattened gain over the C-band. It has a high gain of 35 dB for multi-wavelength preamplification for very small optical signals.
The R35W-C models include the optical components required to extract and split the incoming 1574-nm Fiber Integrity Monitor (FIM) OSC signal to provide dual OSC outputs for delivery to the Rx port of each of the redundant OSU PIUs.
