Pump light source laser for Raman amplifiers
Furthermore, high optical output operation can also be supported as the FOL1439 series has a maximum optical output up to 600mW (Tcase = 70°C) and the FRL1440 has a maximum optical output up to 620mW (Tcase = 70°C).
As it is expected that there will be requirements for even higher output and lower power consumption characteristics in the future, Furukawa Electric will continue to aim for even higher performance enhancements based on the technology in these products.
