<p>The present invention provides byte-interleaving systems and methods for Optical Transport Unit N (OTUN) (i.e. Optical Transport Unit 4 (OTU4)) and 100Gb/s (100G) optical transport enabling multi-level optical transmission. The byte-interleaving systems and methods of the present invention support the multiplexing of sub-rate clients, such as 10Gb/s (10G) clients, 40Gb/s (40G) clients, etc., into two 50Gb/s (50G) logical flows, for example, that can be forward error correction (FEC) encoded and carried on a single wavelength to provide useful, efficient, and cost-effective 100G optical transport today. Signaling format support allows these two 50G logical flows to be forward compatible with an evolving OTU4 and 100G signaling format without waiting for optical and electronic technology advancement. Signaling format support also allows an evolving standard 100G logical flow (i.e. OTU4, 100Gb/s Ethernet (100GbE), etc.) to be carried as 2x50G logical flows, 4x25G logical flows, or other lower rate formats on a single wavelength.</p> |
