Future Optics MWDM z-block is a passive optical subassembly (POSA) based on our free-space-optics wavelength division multiplexing (WDM) platform to deliver optical mux / demux functionality directly inside standard or customized small-form-factor transceivers. Our unique filter based ROSA block and TOSA block are designed to seamlessly integrate with your specific input and output interface.Future Optics Z-block subassemblies are available for various channel center wavelength MWDM4 transceivers and with custom beam pitch designs.
Future Optics 1271.5nm-1341.5nm MWDM Z-BLOCK mux / demux is a very compact TFF optical sub-assembly device acting as an optical engine to combine or to separate channels for high-speed transceivers in data centers and optical communication networks.
Based on thin film filter technology and optical path Zig-Zag design of micro-optics, taking advantage of high precision assembly, this product features small form, ultra-low loss, high channel isolation and exceptional stability in comparison with AWG WDM mux demux device based on silicon chip technology.
The very high parallelism pitch tolerance of Future Optics’MWDM Z-blocks enables a rapid alignment process during coupling and assembly.
Future Optics provide all kinds of MWDM Z-BLOCK mux demux devices with various channel numbers, beam pitches and angle of incidence for customers to choose.
