OTN WAN mapping topics
100G OTN (OTU4/ODU4/OPU4) must support mapping of 100GbE
100GbE line rate of 103.125Gbps (results in OTU4 rate of ~112Gbps w/ FEC)
Full transparency required (donÕt repeat the mistakes made at 10GbE)
100G OTN must support muxing of ODU1/2/3 to new ODU4 layer
OTU4 line rate above 112Gbps is probably not realizable economically with current technology (means ODU4 support 3xODU3 or 4xODU3 is probably not realizable)
Ciena has proposed to ITU a ~112Gbps OTU4 line rate that supports transparent mappings of 100GbE and muxing of ODU1/2e/3e (allowing transparent mappings of 10GbE and 40GbE) and is moving forward with development of this rate
