The document discusses trends and challenges in optical communications and networking. It notes that while fiber capacity experiments have reached 100 terabits per second, the theoretical fiber limit is around 200 terabits per second due to nonlinear effects. It also discusses limitations of CMOS processors and the need for future communication technologies to meet demands for increased capacity, reduced cost per bit, higher energy efficiency, and smaller sizes to enable applications such as medical diagnosis and the Internet of Things. Integrated photonics, electronics, advanced optical subsystems, transmission and reception techniques, and agile optical networks are promising technologies for addressing these challenges that the WTON workshop aims to discuss.

Workshop on Trends in Optical
Communications and
Networking

Vice President of Research & Development

2. OPTICAL COMMUNICATIONS APPLICATIONS
• Today advanced communication Technologies
applications for the society
• Industries, Bussiness/banks, Transportation, Household
and Global knowledge;
• Optical communication research is fruit of combined
efforts in diverse disciplines:
• Physics, photonics, electronics, algorithms and
networks;

3. HIGH CAPACITY COMMUNICATIONS LIMITATIONS
• Fiber capacity crunch
• Today we have noticed 100 Tb/s single mode fiber hero
experiments;
• Theoretical limit are around 200 Tb/s (mainly due
nonlinear effects);
• CMOS ASICs limitations
• Processor frequency does not obey moore law since
year 2000 (Core i7 runs at 3.5GHz)
• CMOS process today is 14nm, and the limitation is about
0.5 nm (two atoms layer);

4. TOMORROW DEMAND NEEDS AND
TECHNOLOGIES
• Tomorrow advanced communication Technologies
applications for the society
• Medical diagnosis and treatment, traffic safety and
Internet of Things;
• New solutions have to meet not just capacity
demand, but all economical perspective
• More capacity, reduced cost/bit, increased energy
efficiency, smaller sizes;

5. HOT COMMUNICATION TECHNOLOGIES
• To attend the high capacity demand, several
Technologies are promissing for the future of
information technology
• Integrated photonics (InP, Silicon photonics);
• Integrated electronics (ASIC design);
• Advanced optical subsystems;
• Advanced Transmission/Reception;
• Agile optical networks;
• WTON main goal is to discuss such technologies R&D&I
