Product Data 954P-P WDM AMPLIFIER PUMP COUPLER
Description
Pump and signal wavelengths are combined in an output fiber of a 2 by 2 port coupler, using fiber with a cut off below 980 such that both signal and pump are guided in the fundamental mode. The device is set for maximum coupling at 1550 nm from primary to secondary fiber. There is little coupling at the shorter wavelength, which has a smaller mode field diameter, therefore the pump light remains in the secondary fiber. All ports are equivalent and can be used as inputs or outputs.
