9. 100G technology overview

10. 100G transmission technology
10G transmission mainly uses NRZ modulation and Direct detection
OOK-NRZ (On Off Keying – None Return to Zero) modulation format
40G transmission: different type of modulation used by different vendors
No real 40G standardization
Direct or coherent detection technology available
100G: Standardization of the line interface
This standardization has caused the technology to mature faster than 40G and therefore will result in a higher adoption rate
Same technology used by all players on the terrestrial 100G market today
DP or PM-QPSK modulation Format and Coherent receiver
Optical design similar for all competitors
Performance differentiation at DSP level
Page 10

11. 100G transmission technology
Routers are rapidly moving toward 100G interconnect to accommodate the increase in IP traffic
Native 100G client interfaces standardized and available
Numerous component vendors have introduced 100G technology to the market in the last 3-6 months causing the economics to improve quickly

12. 100G Competition Status
Field trial over Long haul routes achieved on operators live networks since 2 to 3 years
Few 100G channels added on live 10G and 40G networks
First network deployment announced beginning of last year (2011 H1)
Few Metro Networks already running at 100G
1rst commercial route for 100G traffic: Paris-Frankfurt
Massive 100G network deployment since 2011 H2 and 2012 H1
Transponders (native 100G client ports) and Muxponder (aggregation of 10G client ports in a 100G line available in all 100G players portfolio
Page 12

13. 100G benefits in WDM networks

14. 100G Network design rules
Utilizes the same hardware as 10G and 40G (filters, amps, etc.)
Compatible with all MUX/DMUXs, ROADMs, OADMs, already installed in your network
Works with both 50GHz and 100GHz channel plans
Utilizes standard ITU Grid
Required OSNR around 14 dB
Compatible with the large majority of 10G and 40G installed systems
Transmission over to kilometers
± ps/nm of Chromatic dispersion tolerance
Much more tolerant than the 10G or 40G optical interfaces
10G tolerance around 2000 ps/nm max
PMD tolerance > 30ps (100ps of DGD)
Much more tolerant than the 10G or 40G interfaces
10G tolerance around 10 to 12 ps
Page 14

15. 100G deployment: green field
Green field deployment: new WDM network based on 100G only
High capacity backbone network
Capacity per fiber pair increases by a factor 10 compared to 10G design
Granularity to lower bit rate client ports using Muxponder
Client ports can be 100G, using transponders
Client can also be 40G, 10G or lower by using Muxponder
Infrastructure Cost reduction on network infrastructure due to dispersion compensation removal

Eliminate the need for equipment upgrades to existing 10G systems
Avoid:
Cost of new filters, amps, DCM, etc.
Cost of field tech’s deployment, planning, etc.
Downtime, customer satisfaction / SLA issues
And with a smaller form factor… Eliminate space & power issues
1 RU: Rack chassis even in very tight spaces
230W (4.8A): Run power cables to existing fuse panels
No new power cables to BDP

21. 100G Issues and workaround

22. Ekinops Proprietary information
100G potential issue
Issue with Most 100G solutions
Only available in large form factors not suitable for applications with limited space
Footprint can also be an issue in co-location environments
But: Some low footprint solution are available for limited space
Cost: 100G Muxponder designed for Long haul today remain more expensive the 10 X 10G TRP
But:
a)The cost savings on Infrastructure deployment can reduce the Price Gap for green field deployment
b) 100G standardization with all component suppliers working on the same technology, will lead to efficient price reduction on 100G market

25. 100G Optical Evolution Wave Bounding /SuperChannel
400Gb/s -1Tb/s
100G use 50Gb/s DSP and 25GHz Optical receiver (available today)
1000G (1T) will require 500Gb/s DSP and 250GHz optical receiver
Such type of DSP will not be available before the next decade
Wavebonding: the information is distributed over several subcarriers spaced as closely to form a SuperChannel (example 10 x :500GHz)
10 x 100G = 500GHz
Page 25

26. 100G Optical Evolution Flex Grid
Spectrum efficiency optimization
No need to keep 50GHz between sub carriers 37,5GHz is enough for DP-DPSK
10 x 100G = 500GHz
10 x 100G = 375GHz
Page 26

27. 100G Optical Evolution Flex Grid
Each Sub-Carrier transporting a lower Bit Rate, compatible with current 100G components
Flex-Spectrum DWDM filtering is adopted enabling Multi-carrier add and drop.
Current ROADMs are already compatible with flexgrid
