LWDM filter
AOI 8 air type LWDM filter for compact LWDM

Future Optics provide a large range of standard and customized high quality 8.0 AOI air type LWDM thin film filters used in ultra-compact LWDM Mux Demux devices based on Free-Space Technology. Those compact and low insert loss LWDM modules are specially designed for the purpose to meet demand of new generation communication trend: smaller footprint, higher density and energy efficient, also they are widely used in LANWDM Z-BLOCK Demux.
