  • Method and apparatus for transporting a client layer signal over an optical transport network (OTN)
    Patent number: 7742502
    Abstract: In order to facilitate the transport of 1 Gbit/s Ethernet signals over an Optical Transport Network using the Optical Transport Hierarchy as specified by ITU-T G.709, a new OTH entity referred to as Optical Channel Data Unit-0 (ODU0, 101) with a capacity of approximately 1.22 Gbit/s is defined. This new entity fits perfectly into the existing OTH multiplexing structure, allowing the transport of two times a 1 Gbit/s Ethernet client layer signal within the capacity of one ODU1 (110), while being individually switchable. A 1 Gbit/s Ethernet signal (102) can be mapped into the ODU0 payload (103) using the Transparent Generic Framing Procedure (GFP-T) encapsulation technique as specified in Rec. G.7041.
