100GHz DWDM Filter
100GHz DWDM Filter leverages dense wavelength division multiplexing technology, thin-film coatings, and a proprietary non-flux metal welding micro-optical packaging design to enable upstream and downstream optical signal transmission within the ITU wavelength range. The product employs mature multi-cavity dielectric filters for precise wavelength selection, ensuring excellent wavelength stability and high environmental robustness through sealed packaging. Key features include low insertion loss (≤1.1dB),), high isolation (adjacent ≥30 dB, non-adjacent ≥50dB),), and superior stability and reliability. Widely used in DWDM networks, optical amplifiers, and CATV fiber systems, it supports C-band and L-band ITU channels with 100GHz channel spacing, passband tolerance of ±12.5GHz,, polarization-dependent loss ≤0.2dB,, and polarization mode dispersion ≤0.2ps.. Operating temperature: -5°C to +70°C; storage temperature: -40°C to +85°C. Compatible with SMF-28e fiber, package dimensions: Φ5.5×34 mm.
