Future Optics‘ 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 LWDM transceivers and with custom beam pitch designs.
Future Optics' 8 CH LWDM Mux Demux Z-Block is a LWDM Block to act as a Mux Demux optical sub-assembly for Tosa or Rosa module, working at O-band from 1273.55 to 1309.14 nm, which is integrated inside the transmitting end or receiving end of transceivers to combine 800GHz spacing 8 channels from lasers or to separate 800GHz spacing 8 channels from fiber for PD.
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 the LWDM Z-blocks enables a rapid alignment process during coupling and assembly.
Future Optics provide all kinds of LWDM Z-BLOCK mux demux devices with various channel numbers, beam pitches and angle of incidence for customers to choose.
