8 CH DWDM MUX DEMUX ABS Box for High Density Wavelength Division Multiplexing Applications 1. Low Insertion Loss Design (≤2.4dB) for Enhanced Signal Transmission The 8-channel DWDM MUX/DEMUX adopts advanced thin-film filter (TFF) and arrayed waveguide grating (AWG) technologies, achieving a total insertion loss of ≤2.4dB per channel, a 30% improvement over conventional designs. Optimized optical coupling and anti-reflection coatings ensure ≥25dB channel isolation, effectively
