General Optics
SWDM, CWDM, LWDM Z-BLOCKs
Speed up the assembly of mux/demux components for high-speed optical transceivers with these monolithic Z-blocks that enable a more rapid alignment process.
Coherent Z-block subassemblies deliver a very low insertion loss solution for efficient wavelength multiplexing and demultiplexing in 100G, 400G, 800G systems, and their very high parallelism and pitch tolerances simplify coupling and assembly.
