The PM5990 DIGI-G4 optical transport network (OTN) processor IC targets next-generation switching and packet-optical transport (POTP/P-OTN), WDM/ROADM, and hyperscale data center interconnect equipment. It is said to be the industry’s densest single-chip 4 x 100G OTN processor with 50% less power per port than the previous generation.
The IC increases 10G, 40G and 100G line card port densities by 4X with flexible client mapping of Ethernet, storage, IP/MPLS, and SONET/SDH. It includes a 100G gearbox for direct connect to CFP2, CFP4 and QSFP28 transceivers and multi-rate, sub-180ns latency OTN encryption. It can also dynamically provision, switch, and scale optical connections from 1 to 100 Gbit/s bandwidth without traffic interruption to enable bandwidth-on-demand services. Samples available now.
