The OptiX OSN 9800 U series includes the OptiX OSN 9800 U64, OptiX OSN 9800 U32, and central cluster chassis (CCC). This next-generation large-capacity OTN product series is intended for beyond 200G/400G. It has the industry's highest integration, provides a maximum of five 200G coherent line optical ports in a single slot, and supports future evolution to over 1T. The cross-connect capacity of a single U64/U32 subrack reaches 64T/32T, which can be expanded to more than 200T using clusters, saving equipment room space and improving energy efficiency. The OptiX OSN 9800 U series supports a variety of services, such as Ethernet, OTN, SDH, storage, and video services, and integrates ROADM, 10 Tbit/s universal switching, IEEE 1588v2, synchronous Ethernet, ASON, TSDN, and various management and protection functions. It is the optimal 100G/400G OTN platform in the industry and provides carriers with OTN/WDM transmission solutions featuring ultra broadband, flexible grooming, elasticity, and intelligence.
