Future Optics provide the industry’s advanced telecom mux demux solutions for 200 GHz/100 GHz dense wavelength division multiplexing (DWDM) device with extra low IL, extra compact size and extremely accurate central wavelength, by leveraging proprietary thin-film filter and mini-collimators fixing process, and state-of-the-art optical path length control technique. Custom wavelengths and channel configurations are available upon request.
Future Optics' 20 CH Ultra-Compact Dense Wavelength Division Multiplexer (20 CH UC-DWDM) Mux Demux device is a new version of high desity DWDM mux demux device with ultra compact footprint dimension of 35*27*6.5mm and extremely low insert loss of 2.5dB .
Based on thin film filter and Free-Space technology, taking advantage of patented design of multi-layers optical structure and metal laser welding micro-optics packaging process, Future Optics'20 channels UC-DWDM mux demux devices are of wide channel bandwidth, high precision center wavelength, wide operating temperature range and flexible channel configuration.
Future Optics’ miniature style housing DWDM is the smallest in its class, a new 20 CH UC-DWDM device measures 35mm long by 27mm wide by 5.95 mm thick. This makes it ideal for closely spaced board mounting or for direct use in 0.25inch high splice trays, where space is at a premium.
