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.

SWDM: The Lowest Total Cost Solution for 40G/100G in the Enterprise Data Center
Large- and medium-sized enterprises have been widely deploying 10G Ethernet for several years. Their data center infrastructure has been primarily architected around duplex OM3 and OM4 multimode fiber (MMF), since most of the switch port interfaces are multimode 10GBASE-SR using the SFP+ transceiver form factor.
