The 1536/1554 nm 3-Port Bandpass Filter-Based Wavelength Division Multiplexers are high-performance optical components designed for separating and combining optical signals in fiber-optic communication systems. Based on thin-film interference filter technology, they provide low insertion loss, high channel isolation, low polarization-dependent loss, and excellent temperature stability. Featuring a compact design and an epoxy-free optical path, they ensure reliable wavelength management for EDFA systems and red/blue band separation applications.
