| Single Mode Wavelength Division Multiplexers --WDM-980/1550, 980/1590 |
¡¡The fiber amplifier
WDM enables the combination of pump and signal in C-band 980nm pumped
Erbium Doped fiber Amplifiers (EDFA). The uniquely low insertion loss
of this component, across the whole C-band, enables manufacturers
to achieve the lowest noise figure in their amplifiers. Similarly
low loss in the 980nm window maximizes the pump power reaching the
Erbium fiber. Applications include EDFAs for dense WDM systems, pre
and post amplifiers and optical noise sources. 980/1550nm WDMs are
manufactured using optical fiber with numerical aperture intermediate
between that of signal and gain fiber to enable mode-field matching
and bend-insensitive single mode operation at both wavelengths. |
