100G标准相关 以及 思科所做的开发和2008年业界第一的演示 (及40G和IPoDWDM)100G, 思科, cisco, 40G, IPoDWDM
100Gig E in the IEEE  802.3ba Objectives
• Support full-duplex operation only
• Preserve the 802.3 / Ethernet frame format utilizing the 802.3 MAC
• Preserve minimum and maximum FrameSizeofcurrent 802.3 standard
• Support a BER better than or equal to 10-12at the MAC/PLS service interface
• Provide appropriate support for OTN
• Support a MAC data rate of 40 Gb/s

• Provide Physical Layer specifications which support: 40 Gb/s
–at least 100m on OM3 MMF
–at least 10m over a copper cable assembly
–at least 1m over a backplane

• Support a MAC data rate of 100 Gb/s
• Provide Physical Layer specifications which support:
–at least 40km on SMF
–at least 10km on SMF (likely to become 2-4km)
–at least 100m on OM3 MMF
–at least 10m over a copper cable assembly

100GE and the ITU
1.ITU agreed to optimize new OTU4 rate for 100GE transport
2.Industry appears to have learnt its lesson from 10GE (i.e. LAN/WAN PHY)
Ideally want one mapping, one FEC and one modulation scheme !!!
some resistance from traditional transport vendors

3.Transmission requirements are the same as 40G:
Must work over existing, installed DWDM common equipment;
Support 50GHz DWDM channel spacing;
Full band tunable lasers on 50GHz ITU grid
Optical reach of ≥1,500km;
Chromatic dispersion tolerance of >±800ps/nm;
Polarization Mode Dispersion tolerance of > 10ps (mean DGD);
Must be “plug and play”and installable by existing field technicians

4.40G was the first commercial application for advanced modulation:
100G will build on similar approaches

Cisco 在100G上的开发
1.Leading standardization effort within OIF (eco-system)
Strong supplier base and supply continuity (multiple vendor soln)
Compatibility among system vendors
Share development costs and reduce risks

2.Structure/architecture of the solution
Separate cards for client and trunk
Regenerator uses 2 trunk cards

3.Target Data rates / standards supported
OTU4 trunk as per ITU-T G.709 standard
Multiplexing of 10x10G (10GE, OC192, FC-1200, OTU2)
Multiplexing of 2x40G (OC768, 40GE, OTU3) plus 2x10G (10GE, OC192, FC-1200, OTU2)
100GE Native

Cisco 100GbE 的演示 时间2008年六月
1.Cisco demonstrated world’s first operational 100GbE MAC and router interface
2.Demo included DWDM transmission over production network in Comcast’s network
3.100GbE MAC was based on Cisco’s MLD architecture which is baseline for IEEE 802.3ba
    implemented in FPGA
    very robust architecture
