WDM Optical Fiber Filter Nov 10, 2009

They are specifically designed to multiplex or demultiplex C and L band optical signals in dual-band erbium doped fiber amplifier systems.

1550/1590nm filter wavelength division multiplexing (WDMs) are specifically designed by the fiber optic supplier to multiplex or demultiplex C- and L-band optical signals in dual-band erbium doped fiber amplifier systems.Assembled using advanced filter technology by the fiber optic manufacturer, these stable and reliable filter fiber optic product have high channel isolation, low insertion loss, low temperature dependent loss, and low polarization dependent loss.it suit to use in high channel count systems and extended band systems.
