Filter WDM P1260~1360nm/R1460~1620nm
Filter Wavelength Division Multiplexing (FWDM) is a device for optical wavelength management. It utilizes proven ultra-low-loss thin-film filter (TFF) technology and proprietary design of non-flux metal bonding micro optics packaging. It features small size, high reliability, high extensibility, high channel isolation, epoxy free optical path, simultaneous transmission of multi-wavelength. FWDM has gained prevalence in multi-wavelength digital transport architectures because it enables the use of very low cost uncooled distributed feedback (DFB) laser transmitters. All products meet GR-1209-CORE, GR-1221-CORE requirements.
