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' 6 CH LWDM 1100 Mux Demux 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 and matching with 1.1 mm pitch LD or PD, which is integrated inside the transmitting end or receiving end of transceivers to combine 800GHz spacing 6 channels from lasers or to separate 800GHz spacing 6 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.
