Configuration and ordering notes
Selected when both polarization extinction (≥18-20 dB) and high CW/pulse optical power handling (up to 20W / 10 kW peak) are needed in a rugged aluminum enclosure.
Selection Guidance: Compare TFF vs FBT multiplexing and ASE suppression in our WDM & Optical Filters for EDFA Guide ↗ or PM WDM Selection Guide ↗.
Key Applications
Test instruments; Coherent communication systems; Erbium-doped fiber amplifiers; Fiber sensing.
