7 Optical Fiber: Industry and Performance Optical Fiber ( Millions of km) Long-haul Access Submarine Regional/Metro Premises/Other Results of Bubble work Focus on Access and Low Cost Systems Return to the Capacity Quest! Access driven traffic LH in emerging markets In addition: BR X Reach (km-tb/s) Tb/s in a single fiber achieved in Gb/s and coherent systems becoming commercially available

8 Taking the Risk of Over Simplification Instead of going through some complex systems update, let s try to over simplify things and focus on actual fiber impact 8

9 What is the Best System The more capable or the one that best matches the network requirements? COST COST/BIT CAPACITY CAPACITY COST Optimized for Lower Capacity cost capacity COST/BIT COST/BIT CAPACITY CAPACITY CAPACITY COST æ Optimized for Higher Capacity COST/BIT CAPACITY CAPACITY 9

10 Fiber Impact on Cost/Bit COST/BIT Ref.: SMF-28e + Reference Configuration Reference Fiber Not Interested in higher cost options How can fiber optimization reduce overall cost? CAPACITY Let s start looking at extreme capacity demand networks 10

The New Requirements 10 db Source: Infonetics Research Inc. 2010 1. 100G and beyond 2. Advanced DSP 3.

11 The New Requirements 10 db Source: Infonetics Research Inc G and beyond 2. Advanced DSP 3. DQPSK and PM-QPSK 4. Coherent Systems 5. But 10G will still be there for a long time OSNR 10 G 100 G 11

12 And How Advanced Fiber Technology Can Help A eff / n 2 OSNR out = S P Pch NF N ph Spans Fiber Independent Fiber Effective Area Fiber Attenuation Att. Aeff, F1 n2, F 2 Fiber FOM(dB) 10log( ) ( AttF1 AttF 2) A n eff, F 2 2, F1 L Bergano, OFC 2009, SubOptic

Impact of Attenuation & A eff on the Fiber FOM Example for 100km spans 150 140 130 120 110 100 90 80 70 60 Aeff( um2) 0.23 0.226 0.222 0.218 0.214 0.21 0.206 0.

13 Impact of Attenuation & A eff on the Fiber FOM Example for 100km spans Aeff( um2) Attenuation (db/km)

14 Again, If we over simplify : 0.02 db/km att improv. is equivalent to 50 µm 2 larger Aeff Aeff( um2) Attenuation (db/km)

However These Two Parameters May Have Significantly Different Impact on OSP Management 150 140 0.23 0.226 0.222 0.218 0.214 Standards Independent 0.21 0.206 0.202 0.198 0.194 0.19 0.186 0.

15 However These Two Parameters May Have Significantly Different Impact on OSP Management Standards Independent Attenuation (db/km) Standards Dependent Aeff( um2)

16 If we over simplify : 0.02 db/km att improv. is equivalent to 50 µm 2 larger Aeff POSSIBLE, BUT SAME FOM and NON STD COMPLIANT SMF-28 ULL Aeff( um2) Attenuation (db/km)

If Standards or Installed Plant Compatibility is Not an Issue, them Optimize Both Aeff and Attenuation! Example: Vascade EX 2000 150 140 130 120 110 100 90 80 70 60 Aeff( um2) 0.23 0.226 0.

17 If Standards or Installed Plant Compatibility is Not an Issue, them Optimize Both Aeff and Attenuation! Example: Vascade EX Aeff( um2) Attenuation (db/km)

higher cost options How can fiber optimization reduce overall cost?

18 Fiber Impact on Cost/Bit COST/BIT Ref.: SMF-28e + Reference Configuration Reference Fiber Not Interested in higher cost options How can fiber optimization reduce overall cost? CAPACITY Let s start looking at extreme capacity demand networks Let s now look at moderatehigh cap. demand networks 18

19 Fundamentals Are the Same! So, start by keeping A eff as high as possible and Attenuation as low as possible A eff / n 2 OSNR out = S P Pch NF N ph Spans Fiber Independent Fiber Effective Area Fiber Attenuation Att. Aeff, F1 n2, F 2 Fiber FOM(dB) 10log( ) ( AttF1 AttF 2) A n eff, F 2 2, F1 L Bergano, OFC 2009, SubOptic

20 Focus Now is Simplification - Not Ultimate Capacity G.655 fiber can enable reduction of DCMs and use of singe-stage EDFAs G.652 fiber TX RX Dispersion Two stage EDFAs with mid-stage DCM Receiver Dispersion Tolerance G.655 fiber TX RX Dispersion DCMs eliminated, enabling the use of simpler lower cost single-stage EDFAs Receiver Dispersion Tolerance 20

21 Value of Lower Dispersion Fibers in Networks Based on Simpler and Cost Effective 10 G Solutions Lower dispersion of G.655 fibers Enables use of fewer DCMs Enables use of single-stage stage EDFAs Smaller Lower power consumption Lower opex (space & power) Lower system cost Lower CO 2 emissions 21
