Abstract
The present invention provides byte-interleaving systems and methods for Optical Transport Unit N (OTUN) (i.e. Optical Transport Unit 4 (OTU4)) and 100 Gb/s (100 G) 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 10 Gb/s (10 G) clients, 40 Gb/s (40 G) clients, etc., into two 50 Gb/s (50 G) 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 100 G optical transport today. Signaling format support allows these two 50 G logical flows to be forward compatible with an evolving OTU4 and 100 G signaling format without waiting for optical and electronic technology advancement. Signaling format support also allows an evolving standard 100 G logical flow (i.e. OTU4, 100 Gb/s Ethernet (100 GbE), etc.) to be carried as 2×50 G logical flows, 4×25 G logical flows, or other lower rate formats on a single wavelength.
