Multi Channel FWDM Filter WDM Steel Tube Communication Equipment
FTTX Filter WDM modules are extensively used in EDFA, Raman amplifiers, WDM networks, and fiber optics instrumentation. Based on Thin Film Filter (TFF) technology, these devices combine or separate light at different wavelengths across a wide range. They expand the capacity of single fibers to enable bidirectional communication, making them ideal for optical network upgrades, expansions, and introducing comprehensive new services.
We provide customized filter-based wavelength division multiplexing (WDM) devices tailored to specific wavelength bands for specialized applications. In GEPON systems operating at 1310/1490nm, CATV signals are delivered over the same fiber using 1550nm, with FWDM serving as the mixing point.
