F-tone's Raman amplifier module is an intelligent pump unit for distributed Raman amplification. The Raman amplifier module can accommodate two or three pumps (multiple wavelengths) for C or L-band amplification, and includes full and comprehensive electronic control. The dual and triple-pump models have a maximum output power of 700 mW and 1 W, respectively. Using patent pending technology, the Raman pump unit can operate in full automatic gain control (AGC) mode, thus allowing the Raman gain to be set with an accuracy of +/-0.7 dB.
Features
Supports both co- and counter-propagating configurations
